Yellow fever is a hemorrhagic condition. Therefore, it can lead to a high fever, bleeding, and cell death in the liver and kidneys. If enough liver cells die, liver damage occurs, leading to jaundice. This is a condition in which skin takes on a yellowish color. In addition, the Yellow fever virus is an RNA virus that belongs to the gun flavivirus. Transmitting to people primarily through the bite of infected Aedes species mosquitoes. Yellow fever virus has three transmission cycles. They include:

Jungle cycles – this involves the transmission of viruses between non-human primates. Furthermore, the transmission of viruses is by mosquitoes from monkeys to humans.

Intermediate cycle- this exists that involves the transmission of the virus from mosquitoes to humans living in jungle border areas.

Urban cycles- involves the transmission of the virus between human and urban mosquitoes, primarily Aedes aegypt.





Aching muscles.




Loss of appetite.


A flavivirus causes it. Therefore, these mosquitoes thrive in and near human habitations. This is where they breed in even the cleanest water. However, most cases of the illness occur in sub-Saharan.


No antiviral medications have helped treat it. As a result, treatment consists primarily of supportive care in a hospital. However, rest, drink fluids, and use painkillers to reduce fever and relieve aching. Therefore, avoid certain medications such as aspirin, which may increase the risk of bleeding. People with severe symptoms of the infection should be hospitalized for close observation.

Yellow fever diagnosis.

laboratory diagnosis of yellow fever is generally done by testing serum. This is to detect virus-specific IgM and neutralize antibodies. However, the confirmation is done after the doctor detects the signs and symptoms and carries out a blood test. In addition, a blood test is necessary because other diseases have similar signs and symptoms. A blood test may reveal slide-in white blood cells. Furthermore, the results may take several days.

Vaccination of yellow fever.

The yellow fever vaccines protect against yellow fever for at least 10 years. However, administering should be done before visiting a region for the first time. Travelers need to have the vaccination. This is to increase their protection and spread the disease to others.
