Mosquito Disease Symptoms

From mildly annoying to deadly, the aftermath of mosquito bites stretch the gamut of the spectrum.

Not every mosquito has a vector-borne illness such as West Nile Virus, Zika, dengue or chikungunya. We know for a fact, however, that these are present: The Centers for Disease Control (CDC) reported that in 2017, West Nile Virus affected 47 states and the District of Columbia. Zika is a newcomer to the United States; it was first prevalent in Brazil and other South American countries. In 2017, there were 452 symptomatic Zika cases reported, according to the CDC.

The question is not "if" you will be bitten by a mosquito, it is "when" you will be bitten by a mosquito. What are the symptoms you need to look for? The most common symptoms of mosquito-borne illnesses are fatigue, fever and headache. If you experience these symptoms along with some of these other mosquito-borne illness characteristics, it's important to seek medical attention as soon as possible. This is particularly true if you have traveled outside the country to areas that are more "notorious" for their infected mosquito populations. These include tropical areas like Puerto Rico, Hawaii, Brazil and areas of the southern United States.

West Nile Virus (WNV)

Along with headache, fever and fatigue, West Nile Virus presents with back and body aches, stiff neck, vomiting and/or nausea. The most serious complication of WNV is meningitis, which is an inflammation of the brain that can be potentially fatal.


This recent North American illness had been common in Asia; it has recently spread to the Caribbean and the southern United States. It is characterized by acute joint pain, rash and swelling. The joint pain can last for days, weeks or months.


Although it is common to not display any symptoms or to experience very mild symptoms, the more severe Zika symptoms include rash, joint pain, conjunctivitis and muscle plain. A blood test must be used to confirm a Zika infection.

Dengue Fever

An individual infected with the dengue virus will likely have a stiff neck, will experience confusion, pain behind the eyes and bleeding gums. Also common is fever, fatigue, pain in the muscles, joints and bones.

If you suspect that you have any of these illnesses, it's important to seek medical help. The first line of defense against mosquito-borne illnesses is preventing mosquito bites.
