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 their life.
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.
How does it spread?
Dengue viruses are spread to people through the bites of infected mosquitoes, mainly Aedes aegypti mosquitoes.
The virus that causes COVID-19 is thought to spread mainly through respiratory droplets produced when an infected person coughs, sneezes, or talks.
