- Aedes aegypti and Aedes albopictus can spread Zika virus, dengue fever and chikungunya diseases. While many people who are infected with Zika or chikungunya will not become sick or develop symptoms, some will. Zika virus has been found to be especially harmful to a developing fetus and can cause severe birth defects.
- People who are infected with the virus that causes dengue fever can develop symptoms up to two weeks after being bitten by an infected mosquito. Symptoms often end in about one week. Sometimes symptoms can be severe and include intense stomach pain, repeated vomiting, bleeding from the nose/gums. Sometimes death can occur.
