Dengue fever and Yellow fever, two mosquito-borne diseases, are reportedly making a resurgence. Dengue fever, also known as 'breakbone fever', is a viral illness transmitted by the Aedes mosquito. Symptoms include high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. The New York Times reports that there is no specific treatment for dengue, but early detection and access to proper medical care can lower fatality rates below 1%.
On the other hand, Yellow fever, a disease that was a scourge in the 1800s, is also reportedly making a comeback. The New York Post, Newsmax, and SciTechDaily all report on the resurgence of this disease. Yellow fever is caused by a virus that is also spread by mosquitoes. Symptoms include fever, chills, loss of appetite, nausea, muscle pains particularly in the back, and headaches. Severe cases can cause yellow skin, hence the name, and can be fatal. Vaccination is the most important preventive measure against Yellow fever.
Infectious disease experts warn that the U.S. should brace for a resurgence of Yellow fever, as reported by SciTechDaily. The reasons for the resurgence of these diseases are not explicitly stated in the articles, but it is important to note that changes in climate, increased travel, and decreased immunity could potentially contribute to the increase in cases.
