In how did you know had the yellow fever?

Yellow fever is a mosquito-borne viral infection that can cause fever, jaundice, and bleeding. The symptoms of yellow fever can vary from person to person, and some people may not experience any symptoms at all.

In most cases, yellow fever symptoms appear within 3 to 6 days after being bitten by an infected mosquito. The initial symptoms of yellow fever can include:

* Fever

* Chills

* Headache

* Muscle aches

* Back pain

* Nausea

* Vomiting

* Fatigue

* Loss of appetite

After a few days, some people may develop more severe symptoms, such as:

* Jaundice (yellowing of the skin and eyes)

* Bleeding from the nose, mouth, or gums

* Kidney failure

* Liver failure

* Shock

* Death

If you think you may have yellow fever, it is important to see a doctor right away. There is no specific treatment for yellow fever, but supportive care can help to improve symptoms and prevent complications.

Some people who have yellow fever may also develop a condition called "black vomit." This is a rare but serious complication that can occur when the liver is severely damaged. Black vomit is caused by bleeding in the stomach and intestines, and it can be fatal.

If you are traveling to an area where yellow fever is present, it is important to get vaccinated against the disease before you go. The yellow fever vaccine is very effective at preventing yellow fever, and it is the best way to protect yourself from this serious disease.
