How does COVID-19 compare to the flu?
Flu and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus (called SARS-CoV-2) and seasonal flu (most often just called “flu”) is caused by infection with one of many influenza viruses that spread annually among people.

How long can you be contagious after you test positive for COVID-19?
Even though a person is less likely to transmit the virus later in the course of illness, it’s still possible.

An outbreak is called an epidemic when there is a sudden increase in cases. As COVID-19 began spreading in Wuhan, China, it became an epidemic. Because the disease then spread across several countries and affected a large number of people, it was classified as a pandemic.
What temperature kills the virus that causes COVID-19?
In order to kill COVID‐19, heat virus‐containing objects for: 3 minutes at temperature above 75°C (160°F). 5 minutes for temperatures above 65°C (149°F). 20 minutes for temperatures above 60°C (140°F).
Are there different types of coronaviruses other than COVID-19?

What is a pandemic?
A pandemic is when a disease affects the global population. Pandemics are usually caused by new infectious agents (bacteria or viruses) that spread quickly. A pandemic is a type of epidemic, however a pandemic involves the number of people and the geographical area that the disease affects.
