Chikungunya is a viral disease transmitted to humans through the bite of infected Aedes mosquitoes. These mosquitoes are also known to spread other diseases like dengue and Zika. House flies are not vectors of viral diseases like chikungunya. They typically act as mechanical carriers of bacteria and pathogens that cause diseases such as diarrhea. Cockroaches are primarily associated with spreading bacterial diseases and allergens through contaminated food and surfaces. The female Anopheles mosquito is the vector for malaria.
