Mosquitoes transmit some of the world’s most dangerous diseases, affecting over 700 million people annually and causing more than a million deaths. If you’re wondering what diseases you can get from mosquito bites, here are the most common mosquito-borne illnesses:
- Malaria – Kills over 600,000 people annually through Plasmodium parasites transmitted by mosquito bites
- Dengue Fever – Known as “breakbone fever,” affects up to 100 million yearly with severe flu-like symptoms
- Yellow Fever – Can cause liver disease and death if left untreated
- Zika Virus – Particularly dangerous during pregnancy, can cause serious birth defects
- West Nile Virus – Causes neurological illness in severe cases
- Chikungunya – Results in severe joint pain and high fever
Understanding these mosquito-transmitted diseases is crucial as climate change expands mosquitoes’ range and breeding seasons. Here’s what you need to know about each major mosquito-borne illness and how to prevent them.

Common Mosquito-Borne Diseases: Symptoms and Risks
There are a number of diseases and illnesses you can get from mosquitos. Here are some of the most common ones:
Malaria From Mosquitos
Malaria remains the deadliest disease spread by mosquitoes, with the World Health Organization reporting over 240 million cases annually. Found primarily in sub-Saharan Africa, malaria symptoms include high fever, chills, and flu-like illness. “Malaria’s persistence demonstrates the need for innovative control strategies,” says Dr. Maria Santos of the WHO’s Global Malaria Programme.
Dengue Fever From Mosquitos
Dengue fever, another serious mosquito-transmitted disease, affects up to 100 million people yearly. Scientists at the University of Queensland and North Carolina State University have discovered a promising prevention method using Wolbachia bacteria, which stops mosquitoes from carrying the dengue virus. This breakthrough could protect millions in regions where dengue fever is common.
Zika Virus From Mosquitos
Zika virus and West Nile virus can also spread through mosquito bites, each with unique risks. Zika poses particular dangers during pregnancy, while West Nile virus has become common in many areas, showing why mosquito control matters for public health.
How to Prevent Mosquito-Borne Diseases
Scientists and researchers have been spending decades developing methods to control mosquito populations and prevent illnesses spread by mosquitos. Current prevention strategies include:
Chemical Control:
- Insecticides for adult mosquitoes
- Larvicides to prevent breeding
- Growing challenges with resistance
Biological Control:
- Natural predators that eat mosquitoes
- Beneficial bacteria that reduce mosquito populations
- Environmental-friendly solutions
New scientific approaches show promise in preventing mosquito-transmitted illnesses. Genetic modification and bacterial control lead these innovations. “We’re seeing a shift toward integrated approaches that combine multiple control methods,” explains Dr. James Chen, vector control specialist at the CDC.
Field trials testing these new methods in Australia, Thailand, and Vietnam show encouraging results. Some communities report 75% fewer cases of mosquito-borne diseases after implementing new control strategies.
Impact on Public Health
Effective mosquito control saves lives and money. Communities with good prevention programs see fewer sick days and lower healthcare costs. The World Bank estimates that controlling mosquito-spread diseases could save developing economies over $4 billion annually.
Tourism-dependent regions benefit significantly from reducing mosquito-borne illnesses. “When we control mosquitoes effectively, we protect both public health and economic stability,” notes Dr. Sarah Johnson, health economist at the World Bank.
The Future of Mosquito-Borne Disease Prevention
As mosquito habitats expand due to climate change, preventing mosquito-transmitted diseases becomes more important. New technologies offer hope, but require continued investment and global cooperation. Success stories like the Wolbachia method show we can make progress against these dangerous diseases.
Controlling mosquito-borne illnesses remains a critical public health challenge. Through ongoing research, proven prevention strategies, and new technologies, we can better protect people from diseases spread by mosquitoes. The health of millions depends on these efforts to control mosquito-transmitted diseases.
