কিভাবে কোভিড-১৯, ফ্লু নাকি ডেঙ্গু? covid-19, flu, or dengue? #COVID-19 is caused by infection with the virus strain of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The flu is an infectious respiratory infection caused by influenza viruses that infect the nose, throat, and, occasionally, the lungs. It can cause mild to severe disease and, in extreme cases, death. The easiest approach to avoid flu is to obtain a flu vaccine every year. Dengue fever is a viral infection spread by mosquitos that is present in tropical and subtropical climates worldwide, mostly in urban and semi-urban regions. Dengue virus is the name given to the virus that causes dengue (DENV). There are four DENV serotypes, which means you might be infected four times.
