Yellow fever is spread by the bite of an infected mosquito. The mosquitoes that spread yellow fever are of the Aedes and Haemogogus species, which are found in tropical and subtropical regions of Africa and South America. The virus is primarily transmitted to humans through the bite of an infected mosquito, but it can also be transmitted from person to person via blood or bodily fluids.

Monkeys can carry yellow fever. They are known to be a natural host for the virus, and can act as reservoirs for the disease, meaning that they can carry and spread the virus without showing symptoms themselves. Humans can also contract yellow fever from non-human primates through contact with infected blood or tissues, or from being bitten by a mosquito that has previously bitten an infected monkey.

However, the most common way that yellow fever is transmitted to humans is through the bite of an infected mosquito, not through contact with monkeys or other primates.

Why hasn't yellow fever been eradicated?

Yellow fever has not been eradicated for several reasons:

1. The virus has a complex transmission cycle involving both mosquitoes and primates, making it difficult to completely eliminate. We can't vaccinate all of the monkeys in every African or South American jungle.
2. There is no specific treatment for yellow fever, and the only way to prevent infection is through mosquito control and vaccination.
3. Yellow fever vaccine is not widely available in many countries, particularly in Africa and South America where the disease is most prevalent.
4. In addition, many people in affected areas do not have access to or cannot afford the vaccine.
5. The vaccine also has a short shelf-life and the cost of maintaining a cold-chain distribution is often a barrier for many of these countries.
6. Climate change and population displacement have led to increased expansion of the mosquito vectors to new areas, making the virus more widespread and difficult to control.

Due to these reasons, elimination of yellow fever may be a complex and challenging task, however, large-scale vaccination campaigns and vector control can significantly reduce the transmission of the disease and protect people from yellow fever.

Is there a yellow fever vaccine?

Yes, there is a yellow fever vaccine. The yellow fever vaccine is a live attenuated virus vaccine. The yellow fever vaccine is highly effective and provides long-lasting immunity. The World Health Organization recommends a single dose of the yellow fever vaccine for most people aged 9 months or older who are traveling to or living in yellow fever-endemic areas.

The vaccine is administered as a single subcutaneous injection and it provides protection within one week. The protection lasts for at least 10 years and likely for life.

The Yellow fever vaccine is safe for most people, but certain individuals such as very young infants, pregnant or breastfeeding women, people with weakened immune systems, people with a history of severe allergic reaction to any component of the vaccine or people with certain medical conditions such as thymus disorder or thymectomy. It is important to talk to your doctor if you have any concerns about getting the vaccine.
