It can be transferred through any kind of mosquito. This disease is carried by primates. Yellow fever virus was carried through primates to everyone else. And many people lost their lives because of it. The vaccination to treat yellow fever virus was found a long time after the spread of the disease.
The disease was first found in the 16th century when America was discovered and slaves were transferred from South America to Europe. These slaves carried various kinds of germs because their residential locations were not safe and caused many diseases to spread. This is how yellow fever virus spread. It was in the 20th century that a proper vaccine to treat the dangerous virus was discovered.

Tips and comments
Since yellow fever is a viral disease, no causative cure is actually present. However hospitalization and intense care of the patient is required to treat the yellow fever virus. Patients are given anti viral medicines and are advised to take juices and fruits in order to strengthen their immune system because viral diseases can only be treated by the immune system and the various enzymes produced by the immune system. And if a patient is taking some medicines, then he should not stop because if he does then the virus would become immune and difficult to treat. However great care must be taken to protect one’s self from the disease because the disease has severe after affects which include hair loss, weakness, skin diseases, etc.
