how mosquitoes can spread q disease from an infected person to healthy person
Answers
The mosquito species Aedes aegypti and Aedes albopictus carry dengue, chikungunya and Zika virus. In addition, Aedes aegypti also transmits yellow fever.
Studies done in Gabon and India show that humans can be infected with chikungunya and dengue at the same time.
Entomological studies confirming coinfection in mosquitoes are rare. The Gabon study found one mosquito specimen that was positive for both viruses, meaning that it is possible that the bite of a single mosquito could infect a person with 2 viruses at the same time.
Coinfection poses a challenge for accurate diagnosis and treatment, particularly when symptoms such as fever and aches can be similar for many diseases.
