Mosquitoes transmit yellow fever, most often seen in tropical and subtropical regions. Most people with yellow fever recover within a week after developing symptoms such as a high temperature, headache, chills, and nausea.
However, in addition to liver and renal difficulties, some individuals report a return of symptoms. Jaundice causes the skin to become yellow, thus the name “yellow fever” when the liver begins to fail.
Many nations require passengers to vaccinate against yellow fever before entering their borders. Other governments strongly advise travelers to be vaccinated against yellow fever before visiting an area where it is prevalent.
As the frequency of yellow fever has increased over the last several years, various Asian nations have implemented vaccine requirements for tourists.
In sub-Saharan Africa, nine out of ten cases of yellow fever occur. Ethiopia, Sudan, South Sudan, Chad, Niger, Nigeria, Cameroon, and the Central African Republic are the countries with the highest incidence of yellow fever and where vaccination is highly recommended.
Togo, Liberia, and Cote d’Ivoire are the countries with the lowest incidence of yellow fever and where vaccination is not recommended. Eritrea, Djibouti, Somalia, Tanzania, and Zambia are among African nations where yellow fever is prevalent but not as severe.
Many portions of South America are also affected by yellow fever.
Yellow fever vaccinations are strongly advised for travel to Panama (which is technically in North America but serves as a land bridge between North and South America), Venezuela, Colombia, Trinidad, Guyana, Ecuador, Suriname, French Guiana, Peru, Bolivia, Paraguay, Brazil, and Uruguay, all of which have a high risk of contracting the disease.
Approximately 30,000 people are killed by yellow fever each year. However, this figure is likely underreported due to the prevalence of the disease in war zones and poor communities. Many factors contribute to the rise of cases.
One possible explanation is that instances that have occurred for some time now have been better reported, although there may be others.

Several factors contribute to the spread of the yellow fever virus, including global warming, urbanization, and population growth in places where yellow fever is prevalent.
There is no cure for yellow fever other than managing its symptoms. Preventative medicine, such as vaccination, is the best option.
