It was widely believed it was airborne, or “miasmatic” of the poorly drained and swampy lands which produced unhealthy conditions. The illness ranged from a fever with aches and pains to severe liver disease with bleeding and jaundice (yellow) skin. Mortality rates could be incredibly high, often reaching 50 percent.
Yellow fever (YF) is an African mosquito-borne infection of primates. It is caused by a virus of the Flavivirus genus of the Flaviviridae family. In its natural habitat, it is transmitted between monkeys by forest-dwelling primatophilic Aedes mosquitoes.
The "yellow" in the name refers to the jaundice that affects some patients. Symptoms of yellow fever include fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue. A small proportion of patients who contract the virus develop severe symptoms and approximately half of those die within 7 to 10 days.
Initial symptoms of yellow fever include sudden onset of fever, chills, severe headache, back pain, general body aches, nausea and vomiting, fatigue, and weakness. Most people improve after these initial symptoms.
Anyone can get yellow fever, but older people have a higher risk of severe infection. If a person is bitten by an infected mosquito, symptoms usually develop 3 to 6 days later.
Benjamin Franklin Bache (journalist), died at age 29 in the yellow fever epidemic of 1798 in Philadelphia, Pennsylvania, New Haven, Connecticut and New York City. Richard Bayley, physician, died in 1801 of yellow fever caught while inspecting a ship that had arrived in New York City from Ireland.
Finally, on November 11 1906, the last victim of yellow fever on the Panama Canal died. The yellow fever epidemic was over. After World War II, the world had DDT in its arsenal of mosquito control measures, and mosquito eradication became the primary method of controlling yellow fever.
Rare side effects
These are more common in those over 60 years of age. These include: Yellow fever vaccine associated neurological disease (YEL-AND) is a condition affecting the brain and nervous system, causing symptoms such as confusion and problems with movement and co-ordination.
Yellow fever virus is transmitted to people primarily through the bite of infected Aedes or Haemagogus species mosquitoes.
There is no medicine to treat or cure infection. To prevent getting sick from yellow fever, use insect repellent, wear long-sleeved shirts and long pants, and get vaccinated. There is a safe and effective yellow fever vaccine.
Yellow fever is prevented by a safe, effective and affordable vaccine. People who are one year of age or older must hold an international vaccination certificate if, within six days before arriving in (or returning to) Australia, they have stayed overnight or longer in a declared yellow fever infected country.
While infection of either disease can be fatal, death rates for malaria are significantly higher. Although malaria is treatable and yellow fever is not, malaria is thought to have affected 216 million people and killed almost half a million in 2016 alone.
Abstract. In 1793, during a yellow fever epidemic in Philadelphia, Benjamin Rush adopted a therapy that centered on rapid depletion through purgation and bleeding. His method, especially his reliance on copious bloodletting, was at first widely condemned, but many American practitioners eventually adopted it.
No specific treatment exists for yellow fever, which is one reason that preventative measures such as vaccination are so important. Supportive treatment is aimed at controlling the symptoms, and includes rest, fluids, and use of medicines to help relieve fever and aching.
Those infected would be given treatments of bloodletting in hopes that the disease would be drained from the body. Although, nothing seemed to work until the city started to clean up its street and improving sanitation methods. The city's efforts managed to erase the standing water areas.
Yellow fever is usually found in areas of South America and Africa. People who travel to these areas are at the greatest risk. Most people will not have symptoms. For those that do, symptoms usually start three to nine days after being bitten by an infected mosquito.
The majority of cases recorded in South America involve males 15 to 45 years old, but children in the 1 to 4 years age group also can be affected (Pan American Health Organization, 1983). In Africa, children and young adults up to 15 years of age are mainly affected by the severe form of the disease.
20% to 50% of infected persons who develop severe disease die. Yellow fever virus is transmitted to people primarily through the bite of infected Aedes or Haemagogus mosquitoes.
A single dose provides lifelong protection for most people. The vaccine is a live, weakened form of the virus given as a single shot. Vaccine is recommended for people aged 9 months or older and who are traveling to or living in areas at risk for yellow fever virus in Africa and South America.
More serious reactions happen rarely after yellow fever vaccine. These can include: Nervous system reactions such as inflammation of the brain (encephalitis) and/or spinal cord covering (meningitis), or Guillain-Barré Syndrome (GBS), among others. Life-threatening severe illness with organ dysfunction or failure.
In 1951, Max Theiler of the Rockefeller Foundation received the Nobel Prize in Physiology or Medicine for his discovery of an effective vaccine against yellow fever—a discovery first reported in the JEM 70 years ago. This was the first, and so far the only, Nobel Prize given for the development of a virus vaccine.
Direct spread of yellow fever from one person to another does not occur.
In 2014, the World Health Organization adopted the recommendation to remove the 10-year booster dose requirement from the IHR as of June 2016. Once this change is instituted, a completed International Certificate of Vaccination or Prophylaxis will be valid for the lifetime of the vaccine.
