Ali Maow Maalin
Ali Maow Maalin (; also Mao Moallim and Mao' Mo'allim; 1954 – 22 July 2013) was a Somali hospital cook and health worker from Merca who is the last person known to have been infected with naturally occurring '' Variola minor'' smallpox. He was diagnosed with the disease in October 1977 and made a full recovery. Although he had many contacts, none of them developed the disease, and an aggressive containment campaign was successful in preventing an outbreak. Smallpox was declared to have been eradicated globally by the World Health Organization (WHO) two years later. Maalin was subsequently involved in the successful poliomyelitis eradication campaign in Somalia, and he died of malaria while carrying out polio vaccinations after the re-emergence of the poliovirus in 2013. Early life Ali Maow Maalin was born in 1954 in Merca. Maalin worked as a cook at the hospital in the port town of Merca in southern Somalia, as well as an occasional vaccinator for a WHO smallpox eradica ...

Smallpox
Smallpox was an infectious disease caused by Variola virus (often called Smallpox virus), which belongs to the genus '' Orthopoxvirus''. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person or rarely via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medications could poten ...

Donald Henderson
Donald Ainslie Henderson (September 7, 1928 – August 19, 2016) was an American physician, educator, and epidemiologist who directed a 10-year international effort (1967–1977) that eradicated smallpox throughout the world and launched international childhood vaccination programs. From 1977 to 1990, he was Dean of the Johns Hopkins School of Public Health. Later, he played a leading role in instigating national programs for public health preparedness and response following biological attacks and national disasters. At the time of his death, he was Professor and Dean Emeritus of the Johns Hopkins Bloomberg School of Public Health, and Professor of Medicine and Public Health at the University of Pittsburgh, as well as Distinguished Scholar at the UPMC Center for Health Security. Early life and education Henderson was born in Ohio. His father, David Henderson, was an engineer; his mother, Eleanor McMillan, was a nurse. His interest in medicine was inspired by a Canadian uncl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horn Of Africa
The Horn of Africa (HoA), also known as the Somali Peninsula, is a large peninsula and geopolitical region in East Africa.Robert Stock, ''Africa South of the Sahara, Second Edition: A Geographical Interpretation'', (The Guilford Press; 2004), p. 26 Located on the easternmost part of the African mainland, it is the fourth largest peninsula in the world. It is composed of Somaliland, Somalia, Djibouti, Ethiopia, and Eritrea. Although not common, broader definitions include parts or all of Kenya and Sudan.John I. Saeed, ''Somali'' – Volume 10 of London Oriental and African language library, (J. Benjamins: 1999), p. 250.Sandra Fullerton Joireman, ''Institutional Change in the Horn of Africa'', (Universal-Publishers: 1997), p.1: "The Horn of Africa encompasses the countries of Ethiopia, Eritrea, Djibouti, and Somalia. These countries share similar peoples, languages, and geographical endowments." It has been described as a region of geopolitical and strategic importance, since it ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Vaccination
Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's Adaptive immune system, adaptive immunity, they help prevent sickness from an infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. Herd immunity protects those who may be immunocompromised and cannot get a vaccine because even a weakened version would harm them. The effectiveness of vaccination has been widely studied and verified. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the Eradication of infectious diseases, worldwide eradication of smallpox and the elimination of diseases such as polio and tetanus from much of the world. According to the World Health Organization ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virus
A virus is a submicroscopic infectious agent that replicates only inside the living Cell (biology), cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 16,000 of the millions of List of virus species, virus species have been described in detail. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent viral particles, or ''virions'', consisting of (i) genetic material, i.e., long ...

Measles Vaccine
Measles vaccine protects against becoming infected with measles. Nearly all of those who do not develop immunity after a single dose develop it after a second dose. When the rate of vaccination within a population is greater than 92%, outbreaks of measles typically no longer occur; however, they may occur again if the rate of vaccination decreases. The vaccine's effectiveness lasts many years. It is unclear if it becomes less effective over time. The vaccine may also protect against measles if given within a couple of days after exposure to measles. The vaccine is generally safe, even for those infected by HIV. Most children do not experience any side effects; those that do occur are usually mild, such as fever, rash, pain at the site of injection, and joint stiffness; and are short-lived. Anaphylaxis has been documented in about 3.5–10 cases per million doses. Rates of Guillain–Barré syndrome, autism and inflammatory bowel disease do not appear to be increased by measles ...

Measles
Measles (probably from Middle Dutch or Middle High German ''masel(e)'', meaning "blemish, blood blister") is a highly contagious, Vaccine-preventable diseases, vaccine-preventable infectious disease caused by Measles morbillivirus, measles virus. Other names include ''morbilli'', ''rubeola'', ''9-day measles, red measles'', and ''English measles''. Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than , cough, Rhinitis, runny nose, and conjunctivitis, inflamed eyes. Small white spots known as Koplik's spots, Koplik spots may form inside the mouth two or three days after the start of symptoms. A red, flat rash which usually starts on the face and then spreads to the rest of the body typically begins three to five days after the start of symptoms. Common complications include diarrhea (in 8% of cases), Otitis media, middle ear infection (7%), and pneumonia (6%). These occur i ...

The Boston Globe
''The Boston Globe,'' also known locally as ''the Globe'', is an American daily newspaper founded and based in Boston, Massachusetts. The newspaper has won a total of 27 Pulitzer Prizes. ''The Boston Globe'' is the oldest and largest daily newspaper in Boston and tenth-largest newspaper by print circulation in the nation as of 2023. Founded in 1872, the paper was mainly controlled by Irish Catholic interests before being sold to Charles H. Taylor and his family. After being privately held until 1973, it was sold to ''The New York Times'' in 1993 for $1.1billion, making it one of the most expensive print purchases in United States history. The newspaper was purchased in 2013 by Boston Red Sox and Liverpool F.C. owner John W. Henry for $70million from The New York Times Company, having lost over 90% of its value in 20 years. The chief print rival of ''The Boston Globe'' is the '' Boston Herald'', whose circulation is smaller and is shrinking faster. The newspaper is "one ...

Poliomyelitis
Poliomyelitis ( ), commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to what the person had during the initial infection. Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal–oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral–oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed by ...
