Mosquito Transmission
Mosquitoes thrive in the high temperatures and humidity of the Bolivian lowlands and it was that region which saw the highest numbers of infected civilians. There is currently no vaccine for dengue fever. Those infected experience flu-like symptoms such as severe headaches, fevers and joint pain. The infected are advised by medical experts to drink lots of fluids and obtain significant rest.

Symptoms for such a progression include hypothermia, vomiting, severe abdominal pain and confusion. The global average case-fatality ratio for dengue hemorrhagic fever is 5%.
