Dengue and COVID-19

Dengue viruses and the virus that causes COVID-19 can cause similar symptoms in the early stages.

Dengue

COVID-19

Dengue

Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4. For this reason, a person can be infected with a dengue virus multiple times in his or her lifetime.

COVID-19

Coronavirus disease 2019 or COVID-19 is a respiratory illness caused by a coronavirus called SARS-CoV-2. It is unclear if antibodies created from a COVID-19 infection can provide protection against getting infected again.
