Marie Curie

Best known for her pioneering research in the field of radioactivity, the World famous Polish–French physicist and chemist Marie Skłodowska Curie died on 4th July 1934 of aplastic anemia,. She was born 7th Novemer in 1867 in Warsaw, Poland. Maria’s paternal grandfather, Józef Skłodowski, had been a respected teacher in Lublin, where he taught the young Bolesław Prus,who became a leading figure in Polish literature.Her father, Władysław Skłodowski, taught mathematics and physics, subjects that Maria was to pursue, and was also director of two Warsaw gymnasia for boys.After Russian authorities eliminated laboratory instruction from the Polish schools, he brought much of the laboratory equipment home, and instructed his children in its use.

The father was eventually fired by his Russian supervisors for pro-Polish sentiments, and forced to take lower-paying posts. the family also lost money on a bad investment, and eventually chose to supplement their income by lodging boys in the house. Maria’s mother Bronisława operated a prestigious Warsaw boarding school for girls; she resigned from the position after Maria was born.She died of tuberculosis in May 1878, when Maria was ten years old. Less than three years earlier, Maria’s oldest sibling, Zofia, had died of typhus contracted from a boarder.

When she was ten years old, Maria began attending the boarding school of J. Sikorska; next she attended a gymnasium for girls, from which she graduated on 12 June 1883 with a gold medal. After an illness she spent the following year in the countryside with relatives of her father, and the next year with her father in Warsaw, where she did some tutoring. Unable to enroll in a regular institution of higher education because she was a woman, she and her sister Bronisława became involved with the clandestine Flying University, a Polish patriotic institution of higher learning that admitted women students.

At a Warsaw laboratory, in 1890–91, Maria Skłodowska did her first scientific work and made an agreement with her sister, Bronisława, that she would give her financial assistance during Bronisława’s medical studies in Paris, in exchange for similar assistance two years later. Maria took a position as governess: first as a home tutor in Warsaw; then for two years as a governess in Szczuki with a landed family, the Żorawskis, who were relatives of her father and fell in love with their son, Kazimierz Żorawski, a future eminent mathematician.Who soon earned a doctorate and pursued an academic career as a mathematician, becoming a professor and rector of Kraków University. Sadly his parent rejected his relationship with Maria.

She lived inWarsaw until the age of 24, when she followed her older sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. She was also the first person honored with two Nobel Prizes—in both physics and chemistry, In 1903 she won the Nobel Prize in Physics which She shared with her husband Pierre Curie (and with Henri Becquerel), and In 1911 She became the sole winner of the 1911 Nobel Prize in Chemistry which she shared with Her daughter Irène Joliot-Curie and son-in-law, Frédéric Joliot-Curie, and is the only woman to date to win in two fields, and the only person to win in multiple sciences.

Among her many achievements are the theory of radioactivity (a term that she coined), She also developed techniques for isolating radioactive isotopes, and discovered two radioactive elements, polonium (Which was named after her native country) and radium. She was also the first female professor at the University of Paris and Under her direction, the world’s first studies were conducted into the treatment of neoplasms, using radioactive isotopes. In 1932, she founded a Radium Institute (now the Maria Skłodowska Curie Institute of Oncology) in her home town, Warsaw. The Institute was headed by her physician-sister Bronisława.

Unfortunately though Marie Curie died on 4th July 1934 of aplastic anemia,  Curie’s tragic death at the age of 67 was undoubtedly brought on by her lifelong exposure to radiation, however her pioneering research has led the way for many improvements in the fields of Science, Chemistry and Medicine and in 1995 she became the first woman to be entombed on her own merits in the Paris Panthéon.

National Sunglasses day

National Sunglasses Day takes place annually on 27 June. National Sunglasses Day was launched by the Vision Council on 27 June 2011 to educate people concerning the importance of protecting your eyes from too much Ultraviolet Exposure which can severely damage them. Ultraviolet (UV) designates a band of the electromagnetic spectrum with wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and contributes about 10% of the total output of the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.

Suntan and sunburn are familiar effects of over-exposure of the skin to UV, along with higher risk of skin cancer. Living things on dry land would be severely damaged by ultraviolet radiation from the Sun if most of it were not filtered out by the Earth’s atmosphere. More energetic, shorter-wavelength “extreme” UV below 121 nm ionizes air so strongly that it is absorbed before it reaches the ground. Ultraviolet is also responsible for the formation of bone-strengthening vitamin D in most land vertebrates, including humans (specifically, UVB). The UV spectrum thus has effects both beneficial and harmful to human health. The lower wavelength limit of human vision is conventionally taken as 400 nm, so ultraviolet rays are invisible to humans, although some people can perceive light at slightly shorter wavelengths than this (see below). Insects, birds, and some mammals can see near-UV (i.e. slightly lower wavelengths than humans can see).


Industrial Workers of the World Day

Industrial Workers of the World Day commemorates the founding of the Industrial Workers of the World (IWW), whose members are nicknamed the ‘Wobblies,’ in Chicago Illinois, on 27 June 1905. The Industrial Workers of the World was the first union in the U.S. open to women and men of all races. Some of the union’s better-known members were “Big Bill” Haywood, James Connolly, Eugene V. Debs, Daniel De Leon, Elizabeth Gurley Flynn, Thomas Hagerty, William Trautmann, Lucy Parsons, Frank Bohn, “Mother” Jones, Vincent Saint John, and Ralph Chaplin


National HIV TESTING day

National HIV Testing Day takes place annually on 27 June. The first National HIV Testing Day was initiated by HIV.gov ON the date of 27 June 1995.

National Post Traumatic Stress disorder awareness day

National PTSD Awareness Day takes place annually on the 27th of June to create awareness regarding PTSD (Post Traumatic Stress Disorder). It started in 2010. The PTSD Awareness Camp runs for the whole month of June, also known as PTSD Awareness Month.

Post traumatic stress disorder (PTSD) is a mental disorder that can develop after a person is exposed to a traumatic event, such as sexual assault, warfare, traffic collisions, or other threats on a person’s life. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in how a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event. Young children are less likely to show distress but instead may express their memories through play. A person with PTSD is at a higher risk for suicide and intentional self-harm. Most people who have experienced a traumatic event will not develop PTSD. People who experience interpersonal trauma (for example rape or child abuse) are more likely to develop PTSD, as compared to people who experience non-assault based trauma such as accidents and natural disasters. About half of people develop PTSD following rape. Children are less likely than adults to develop PTSD after trauma, especially if they are under ten years of age. Diagnosis is based on the presence of specific symptoms following traumatic events.

Prevention may be possible when therapy is targeted at those with early symptoms but is not effective when carried out among all people following trauma. The main treatments for people with PTSD are counselling and medication. A number of different types of therapy may be useful This may occur one-on-one or in a group. Antidepressants of the selective serotonin reuptake inhibitor type are the first-line medications for PTSD and result in benefit in about half of people. These benefits are less than those seen with therapy. It is unclear if using medications and therapy together has greater benefit. Other medications do not have enough evidence to support their use and in the case of benzodiazepines may worsen outcomes.

In the United States about 3.5% of adults have PTSD in a given year, and 9% of people develop it at some point in their life. In much of the rest of the world, rates during a given year are between 0.5% and 1%. Higher rates may occur in regions of armed conflict. It is more common in women than me. Symptoms of trauma-related mental disorders have been documented since at least the time of the ancient Greeks. During the World Wars study increased and it was known under various terms including “shell shock” and “combat neurosis”. The term “posttraumatic stress disorder” came into use in the 1970s in large part due to the diagnoses of U.S. military veterans of the Vietnam War. It was officially recognized by the American Psychiatric Association in 1980 in the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III)

There are organizations that helps patients with PTSD and to diagnose PTSD as soon as possible. War veterans or soldiers are at higher risk of PTSD. More than just War veterans or soldiers can get PTSD, and although June is full of back to back military related days, PTSD affects more people other than veterans.

Helen Keller

Helen Keller Day, is held yearly on 27 June to commemorate inspiring deaf-blind American author, political activist, and lecturer Helen Adams Keller, who was born June 27, 1880 and overcame her disability to make a huge impact on the quality of life of deafblind people the world over.

Helen Keller was born with the ability to see and hear. However At age 19 months she contracted an illness described by doctors as “an acute congestion of the stomach and the brain”, which might have been scarlet fever or meningitis. The illness left her both deaf and blind. At that time, she was able to communicate somewhat with Martha Washington, the six-year-old daughter of the family cook, who understood her signs; by the age of seven, Keller had more than 60 home signs to communicate with her family. In 1886, Keller’s mother, inspired by an account in Charles Dickens’ American Notes of the successful education of another deaf and blind woman, Laura Bridgman, dispatched young Helen, accompanied by her father, to seek out physician J. Julian Chisolm, an eye, ear, nose, and throat specialist in Baltimore, for advice. Chisholm referred the Kellers to Alexander Graham Bell, who was working with deaf children at the time.

Bell advised them to contact the Perkins Institute for the Blind, the school where Bridgman had been educated, which was then located in South Boston. Michael Anagnos, the school’s director, asked former student 20-year-old Anne Sullivan, herself visually impaired, to become Keller’s instructor. It was the beginning of a 49-year-long relationship during which Sullivan evolved into governess and then eventual compaion.Anne Sullivan arrived at Keller’s house in March 1887, and immediately began to teach Helen to communicate by spelling words into her hand, beginning with “d-o-l-l” for the doll that she had brought Keller as a present. Keller was frustrated, at first, because she did not understand that every object had a word uniquely identifying it. In fact, when Sullivan was trying to teach Keller the word for “mug”, Keller became so frustrated she broke the doll. Keller’s big breakthrough in communication came the next month, when she realized that the motions her teacher was making on the palm of her hand, while running cool water over her other hand, symbolized the idea of “water”; she then nearly exhausted Sullivan demanding the names of all the other familiar objects in her world. Due to a protruding left eye, Keller was usually photographed in profile. Both her eyes were replaced in adulthood with glass replicas for “medical and cosmetic reasons”.

In 1888, Keller attended the Perkins Institute for the Blind. In 1894, Helen Keller and Anne Sullivan moved to New York to attend the Wright-Humason School for the Deaf, and to learn from Sarah Fuller at the Horace Mann School for the Deaf. In 1896, they returned to Massachusetts and Keller entered The Cambridge School for Young Ladies before gaining admittance, in 1900, to Radcliffe College, where she lived in Briggs Hall, South House. Her admirer, Mark Twain, had introduced her to Standard Oil magnate Henry Huttleston Rogers, who, with his wife Abbie, paid for her education. In 1904, at the age of 24, Keller graduated from Radcliffe, becoming the first deaf blind person to earn a Bachelor of Arts degree. She maintained a correspondence with the Austrian philosopher andpedagogue Wilhelm Jerusalem, who was one of the first to discover her literary talent. Determined to communicate with others as conventionally as possible, Keller learned to speak, and spent much of her life giving speeches and lectures. She learned to “hear” people’s speech by reading their lips with her hands—her sense of touch had become extremely subtle. She became proficient at using Braille and reading sign language with her hands as well Shortly before World War I, with the assistance of the Zoellner Quartet she determined that by placing her fingertips on a resonant tabletop she could experience music played close by

Keller went on to become a world-famous speaker and author. She is remembered as anadvocate for people with disabilities, amid numerous other causes. She was a suffragist, apacifist, an opponent of Woodrow Wilson, a radical socialist and a birth control supporter. In 1915 she and George Kessler founded the Helen Keller International (HKI) organization. This organization is devoted to research in vision, health and nutrition. In 1920 she helped to found the American Civil Liberties Union (ACLU). Keller traveled to 40 some-odd countries with Sullivan, making several trips to Japan and becoming a favorite of the Japanese people. Keller met every U.S. President from Grover Cleveland to Lyndon B. Johnson and was friends with many famous figures, including Alexander Graham Bell, Charlie Chaplin and Mark Twain. Keller and Twain were both considered radicals at the beginning of the 20th century, and as a consequence, their political views have been forgotten or glossed over in popular perception. Keller was a member of the Socialist Party and actively campaigned and wrote in support of the working class from 1909 to 1921.

she supported Socialist Party candidate Eugene V. Debs in each of his campaigns for the presidency. Newspaper columnists who had praised her courage and intelligence before she expressed her socialist views now called attention to her disabilities. Keller joined the Industrial Workers of the World (known as the IWW or the Wobblies) in 1912, saying that parliamentary socialism was “sinking in the political bog”. She wrote for the IWW between 1916 and 1918. In Why I Became an IWW, Keller explained that her motivation for activism came in part from her concern about blindness and other disabilities:I was appointed on a commission to investigate the conditions of the blind. For the first time I, who had thought blindness a misfortune beyond human control, found that too much of it was traceable to wrong industrial conditions, often caused by the selfishness and greed of employers. And the social evil contributed its share. I found that poverty drove women to a life of shame that ended in blindness.The last sentence refers to prostitution and syphilis, the former a frequent cause of the latter, and the latter a leading cause of blindness. In the same interview, Keller also cited the 1912 strike of textile workers in Lawrence, Massachusetts for instigating her support of socialism.

Keller was a prolific author, and wrote a total of 12 published books and several articles. One of her earliest pieces of writing, at age 11, was The Frost King (1891). There were allegations that this story had been plagiarized from The Frost Fairies by Margaret Canby. An investigation into the matter revealed that Keller may have experienced a case ofcryptomnesia, which was that she had Canby’s story read to her but forgot about it, while the memory remained in her subconscious. At age 22, Keller published her autobiography, The Story of My Life (1903), with help from Sullivan and Sullivan’s husband, John Macy. It recounts the story of her life up to age 21 and was written during her time in college. Keller wrote The World I Live In in 1908, giving readers an insight into how she felt about the world. Keller was well-travelled and outspoken in her convictions. A member of the Socialist Party of America and the Industrial Workers of the World, she campaigned for women’s suffrage, labor rights, socialism, and other radical left causes. She also wrote Out of the Dark, a series of essays on socialism, which was published in 1913.

When Keller was young, Anne Sullivan introduced her to Phillips Brooks, who introduced her to Christianity, Keller famously saying: “I always knew He was there, but I didn’t know His name!” Her spiritual autobiography, My Religion, was published in 1927 and then in 1994 extensively revised and re-issued under the title Light in My Darkness. It advocates the teachings of Emanuel Swedenborg, the Christian revelator and theologian who gives a spiritual interpretation of the teachings of the Bible and who claims that the second comingof Jesus Christ has already taken place. Adherents use several names to describe themselves, including Second Advent Christian, Swedenborgian, and New Church. The story of how Keller’s teacher, Anne Sullivan, broke through the isolation imposed by a near complete lack of language, allowing the girl to blossom as she learned to communicate, has become widely known through the dramatic depictions of the play and film The Miracle Worker.

Sadly Keller suffered a series of strokes in 1961 and spent the last years of her life at her home. On September 14, 1964, President Lyndon B. Johnson awarded her the Presidential Medal of Freedom, one of the United States’ two highest civilian honors. In 1965 she was elected to the National Women’s Hall of Fame at the New York World’s Fair. Keller devoted much of her later life to raising funds for the American Foundation for the Blind. She died in her sleep on June 1, 1968, at her home, Arcan Ridge, located in Easton, Connecticut, a few weeks short of her eighty-eighth birthday. A service was held in her honor at the National Cathedral in Washington, D.C., and her ashes were placed there next to her constant companions, Anne Sullivan and Polly Thompson. She was inducted into the Alabama Women’s Hall of Fame in 1971 and Helen Keller Day was authorized in her honour at the federal level by presidential proclamation by President Jimmy Carter in 1980, her 100th birthday.

Nystagmus Awareness Day

Nystagmus Awareness Day takes place on 20 June. The event was created by the Nystagmus Network to increase awareness and educate people concerning the condition and treatment of Nystagmus. Nystagmus causes involuntary (or voluntary, in rare cases) eye movement, acquired in infancy or later in life, that may result in reduced or limited vision and may be symptomatic of problems with the visual pathway. Due to the involuntary movement of the eye, it has been called “dancing eyes”.

In a normal condition, while the head rotates about an axis, distant visual images are sustained by rotating eyes in the opposite direction on the respective axis. The semicircular canals in the vestibule of the ear sense angular acceleration. These send signals to the nuclei for eye movement in the brain. From here, a signal is relayed to the extraocular muscles to allow one’s gaze to fixate on one object as the head moves. Nystagmus occurs when the semicircular canals are being stimulated (e.g. by means of the caloric test, or by disease) while the head is not in motion. The direction of ocular movement is related to the semicircular canal that is being stimulated.

There are two key forms of nystagmus: pathological and physiological, with variations within each type. Nystagmus may be related to albinism and is also occasionally associated with vertigo. However it can also be caused by cataracts, glaucoma, congenital disorder, sleep deprivation, acquired or central nervous system disorders, toxicity, pharmaceutical drugs, alcohol, or rotational movement. Nystagmus was Previously considered untreatable, however in recent years several drugs have been identified for treatment of nystagmus.

World Sickle Cell Day

World Sickle Cell Day occours yearly on 19th June to raise awareness of InteSickle-cell disease (SCD), or sickle-cell anaemia (SCA) or drepanocytosis. Sickle Cell disease is a hereditary group of blood disorders typically inherited from a person’s parents. It is characterized by red blood cells that assume an abnormal, rigid, sickleshape. This so called “Sickling” of the red blood cells decreases the cells’ flexibility and results in a risk of various complications. The sickling occurs because of a mutation in the haemoglobin gene. Individuals with one copy of the defunct gene display both normal and abnormal haemoglobin. This is an example of codominance. In 1994, in the US, the average life expectancy of persons with this condition was estimated to be 42 years in males and 48 years in females. The average life expectancy in the developed world is 40 to 60 years However, thanks to better management of the disease, some patients can now live into their 70s or beyond.

The condition was first described in the medical literature by the American physician James B. Herrick in 1910. In 1949, the genetic transmission was determined by E. A. Beet and J. V. Neel. In 1954, the protective effect against malaria of sickle cell trait was described. Sickle-cell disease occurs more commonly among people whose ancestors lived in tropical and sub-tropical sub-saharan regions where malaria is or was common. Where malaria is common, carrying a single sickle-cell gene (sickle cell trait) confers a fitness. Specifically, humans with one of the two alleles of sickle-cell disease show less severe symptoms when infected with malaria.

Sickle-cell anaemia is a form of sickle-cell disease in which there is homozygosity for themutation that causes HbS. Sickle-cell anaemia is also referred to as “HbSS”, “SS disease”, “haemoglobin S” or permutations of those names. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances. In heterozygous people, that is, those who have only one sickle gene and one normal adult haemoglobin gene, the condition is referred to as “HbAS” or “sickle cell trait”. Other, rarer forms of sickle-cell disease arecompound heterozygous states in which the person has only one copy of the mutation that causes HbS and one copy of another abnormal haemoglobin allele. They include sickle-haemoglobin C disease (HbSC), sickle beta-plus-thalassaemia (HbS/β+) and sickle beta-zero-thalassaemia (HbS/β0). The term disease is applied because the inherited abnormality causes a pathological condition that can lead to death and severe complications. However Not all inherited variants of haemoglobin are detrimental, a concept known as genetic polymorphism.

Sickle cell disease occurs when a person inherits two abnormal copies of the haemoglobin gene, one from each parent. This gene occurs in chromosome 11. Several subtypes exist, depending on the exact mutation in each haemoglobin gene. An attack can be set off by temperature changes, stress, dehydration and high altitude. A person with a single abnormal copy does not usually have symptoms and is said to have sickle cell trait. Such people are also referred to as carriers. Diagnosis is by a blood test, and some countries test all babies at birth for the disease. Diagnosis is also possible during pregnancy.

Problems in sickle cell disease typically begin around 5 to 6 months of age. A number of health problems may develop, such as attacks of pain (“sickle cell crisis”), anemia, swelling in the hands and feet, bacterial infections and stroke. Long-term pain may develop as people get older. The care of people with sickle cell disease may include infection prevention with vaccination and antibiotics, high fluid intake, folic acid supplementation and pain medication. Other measures may include blood transfusion and the medication hydroxycarbamide (hydroxyurea). A small percentage of people can be cured by a transplant of bone marrow cells. .

As of 2015, about 4.4 million people have sickle cell disease, while an additional 43 million have sickle cell trait.About 80% of sickle cell disease cases are believed to occur in Sub-Saharan Africa. It also occurs relatively frequently in parts of India, the Arabian Peninsula and among people of African origin living in other parts of the world. In 2015, it resulted in about 114,800 deaths.

World Blood Doner Day

World Blood Doner day takes place annually on 14 June to celebrate the birth of Austrian Biologist, physician and Scientist Karl Landsteiner who was born on 14 June in 1868. Karl Landsteiner was the first person to distinguish the main blood groups in 1900, having developed the modern system of classification of blood groups from his identification of the presence of agglutinins in the blood, and identified the Rhesus factor with Alexander S. Wiener in 1937. These discoveries enabled physicians to safely transfuse blood without endangering the patient’s life. He also discovered the polio virus in 1909 With Constantin Levaditi and Erwin Popper. Following his revolutionary discoveries He received the Aronson Prize in 1926 and In 1930, he received the Nobel Prize in Physiology or Medicine. He was posthumously awarded the Lasker Award in 1946, and has been described as the father of transfusion medicine.

The aim of World Blood Doner Day is to raise awareness of the need for safe blood and blood products, and to thank blood donors for their voluntary, life-saving gifts of blood which helps save millions of lives every year. The transfusion of blood can help patients suffering from life-threatening conditions live longer and with higher quality of life, and supports complex medical and surgical procedures. It also has an essential, life-saving role in maternal and perinatal care. Access to safe and sufficient blood and blood products can help reduce rates of death and disability due to severe bleeding during delivery and after childbirth. In many countries, there is not an adequate supply of safe blood, and blood services face the challenge of making sufficient blood available, while also ensuring its quality and safety. An adequate supply can only be assured through regular donations by voluntary unpaid blood donors. The WHO’s goal is for all countries to obtain all their blood supplies from voluntary unpaid donors by 2020. It emphasizes thanking of blood donors who save lives every day through their blood donations and inspires more people all over the world to donate blood voluntarily and regularly with the slogan “Give freely, give often. Blood donation matters.” Many lives (including mine) have been saved thanks to blood transfusions.

Activities include special events, meetings, publication of relevant stories on media, scientific conferences, publication of articles on national, regional and international scientific journals, and other activities that would help in encouraging the title of this year’s World Blood Donor Day. The host country for World Blood Donor Day 2015 was China through its blood center in Shanghai, Shanghai Blood Centre, also the WHO Collaborating Center for Blood Transfusion Services. The focus of the WBDD 2014 campaign was “Safe blood for saving mothers”. The goal of the campaign was to increase awareness about why timely access to safe blood and blood products is essential for all countries, as part of a comprehensive approach to prevent maternal deaths. According to the World Health Organization, 800 women die every day from pregnancy and childbirth-related complications. Severe bleeding is the cause of 34% of maternal deaths in Africa, 31% in Asia and 21% in Latin America and the Caribbean. The global host for the WBDD 2014 event was Sri Lanka. Through its national blood transfusion service, Sri Lanka promotes voluntary unpaid donation to increase access to safe and sufficient blood and blood products.

The host country for World Blood Donor Day 2013 was France. Through its national blood service, the Etablissement Français du Sang (EFS), France has been promoting voluntary non-remunerated blood donation since the 1950s. The focus for the WBDD 2013 campaign – which marked the 10th anniversary of World Blood Donor Day – was blood donation as a gift that saves lives. The WHO encouraged all countries to highlight stories from people whose lives have been saved through blood donation, as a way of motivating regular blood donors to continue giving blood and people in good health who have never given blood, particularly young people, to begin doing so. The 2012 campaign focused on the idea that any person can become a hero by giving blood. Blood cannot yet be manufactured artificially, so voluntary blood donation remains vital for healthcare worldwide. Many anonymous blood donors save lives every day through their blood donations.

World Blood Donor Day is one of eight official global public health campaigns marked by the World Health Organization (WHO), along with World Health Day, World Tuberculosis Day, World Immunization Week, World Malaria Day, World No Tobacco Day, World Hepatitis Day, and World AIDS Day.
