How Long After Mosquito Bite EEE Symptoms (And Why)?

Exact Answer: Within Two Weeks

EEE is a disease that has taken away millions of lives. It is mainly caused due to a bite from either a female Anopheles mosquito or an infected one. They act as the carrier of the parasite Plasmodium, which is transmitted by the mosquito’s bite from its saliva to the person’s blood. After entering the blood, these parasites travel far and wide across the body and attack the liver. Within the liver, they live, mature, and multiply to more parasites.

These increased numbers of parasites are now again freed into the blood, where they attack the RBCs of the blood, thereby infecting them with their influence. These infected RBCs now start producing more parasites which continue to attack more RBCs, thereby leading to a lack of them in the body.

EEE is found in countries located in tropical zones. It is even found in subtropical zones where parasites can easily reside and breed. This is transmitted from people who had traveled to tropical and subtropical areas into people residing there as natives in other countries. There are four types of Parasite Plasmodium. Plasmodium Falciparum leads to congenital EEE, which is quite dangerous than regular EEE and even has more fatality.

Plasmodium EEE is the one that is responsible for EEE. It is either caused by a bite from an infected mosquito. Apart from these, it is even caused due to the transplantation of an organ from an infected person. It may even be caused due to contact of blood from the infected individual. Sharing of needles and other instruments may even lead to the spreading of EEE. The incubation period of the Parasite varies between seven days to three weeks. Sometimes, the parasites start infecting and affecting the body right after entering it. But, in some cases, they initially remain dormant for a particular time, after which they start affecting the body.

The most common symptoms of EEE include headache, high and frequent fever accompanied by chills, vomiting, pain in the abdomen and muscles, presence of blood in stools, and nausea. In more severe cases, typhoid and fatality are even expected. The doctor identifies EEE from the enlargement of the spleen and other organs like the liver. These are the first organs that get affected once any harmful microbes enter the body. They first try to fight with the microbe. Then, on being defeated, they show such abnormality symptoms.

Apart from these signs, if the person experiences or witnesses any signs of EEE, then the doctor would carry out other medical tests to know if EEE persists in the person’s body. Once confirmed, the doctor even carries out further tests to know the type of EEE affecting the patient and the cause of EEE. In these tests, the drugs which should be administered to the patient are even known, and it is even checked whether this disease has affected many other major organs or not.

Sometimes, EEE can lead to other complications which have the potential to lead to death. It may affect the blood vessels of the brain, thereby leading to their swelling. It may even affect the lungs, thereby causing breathing problems. Sometimes, it even causes the excess fatality of RBCs in the body. Anemia, caused due to lack of RBCs, is even caused due to bacteria. Lowering of blood sugar and blood pressure is even noticed in some cases.


Finally, it can be concluded that EEE has become a common deadly disease. No vaccines have been made to prevent this disease. It is only proper precautions regarding hygiene that can prevent EEE. One should try to keep the surrounding environment as clean as possible. Drains and sewage should be properly closed.
