Covid

COVID-19 is caused by a coronavirus called SARS-CoV-2.
It is caused by a virus and not a bacteria.

Coronaviruses are a big family of different viruses.
On December 12, 2019 A cluster of patients in Wuhan, Hubei Providence, China begin to experience shortness of breath and fever. This was the start of Covid-19
Illness caused by SARS-CoV-2 was termed COVID-19 by the World Health Organization, from the words "coronavirus disease 2019." This name was used to avoid stigmatizing the virus's origination location in terms of populations, geography, or any animal association.

How it spreads:
It is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet). It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes. This is not thought to be the main way the virus spreads, but we are still learning more about this virus.

The virus that causes COVID-19 is spreading very easily and sustainably between people. Information from the ongoing COVID-19 pandemic suggests that this virus is spreading more efficiently than influenza, but not as efficiently as measles, which is highly contagious.

Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick.
Incubation period:
On average, symptoms showed up in the newly infected person about 5 days after contact. Rarely, symptoms appeared as soon as 2 days after exposure. Most people with symptoms had them by day 12. And most of the other ill people were sick by day 14.
In rare cases, symptoms can show up after 14 days.
On March 11, 2020, the World Health Organization declared COVID-19 a global pandemic, its first such designation since declaring H1N1 influenza a pandemic in 2009.

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)
