Why Mosquitoes Are More Dangerous Than Many People Realize
Mosquitoes are not just irritating insects. They are vectors, meaning they can transmit viruses, parasites, and pathogens between humans and animals.
When an infected mosquito bites a person, disease-causing organisms may enter the bloodstream.
Mosquitoes spread illnesses including:
-
West Nile virus
-
Dengue fever
-
Malaria
-
Zika virus
-
Chikungunya
-
Yellow fever
-
Japanese encephalitis
-
