Answers
Answer:
Hehe
Explanation:
Coronaviruses, like the new COVID-19 outbreak that began in China, cause mild to severe respiratory illness including death. COVID-19 has since spread worldwide. The best preventive measures include wearing a mask, staying six feet apart, washing hands often, avoiding sick people, keeping your hands away from your face and getting adequate rest and nutrition.

OVERVIEW
Microscopic Rendering of Coronavirus
Coronavirus disease 2019 (COVID-19) is a virus (more specifically, a coronavirus) identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China.
What is coronavirus?
Coronaviruses are a family of viruses that can cause respiratory illness in humans. They get their name, “corona,” from the many crown-like spikes on the surface of the virus. Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and the common cold are examples of coronaviruses that cause illness in humans.
The new strain of coronavirus, COVID-19, was first reported in Wuhan, China in December 2019. The virus has since spread to all continents (except Antarctica).

How many people are infected with COVID-19?
The number of people infected changes daily. Organizations that collect this information, including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), are gathering information and continuously learning more about this outbreak. As of this writing (04/1/2021), more than 129,000,000 people in the world have been infected. Over 2,800,000 people have died. Some 192 countries and territories on all continents (except Antarctica) have now reported cases of COVID-19. The U.S. has the highest number of cases, with more than 30,500,000 people infected and over 550,000 deaths. Brazil has more than 12,700,000 cases and 320,000 deaths; India has over 12,200,000 cases; France has over 4,700,000 cases; Russia and England have over 4,300,000 cases; Italy has more than 3,600,000, Turkey has over 3,300,000 cases, Spain has over 3,200,000 cases; Germany has more than 2,800,000 cases; Columbia has 2,400,000 cases; Poland and Argentina have over 2,300,000 and Mexico has over 2,200,000 cases.

How does the new coronavirus (COVID-19) spread from person to person?
COVID-19 is likely spread:
When the virus travels in respiratory droplets when an infected person coughs, sneezes, talks, sings or breathes near you (within six feet). This is thought to be the main way COVID-19 is spread.
When the virus travels in small respiratory droplets that linger in the air for minutes to hours from an infected person who is more than six feet away or has since left the space. This method of spread is more likely to occur in enclosed spaces with poor ventilation.
From close contact (touching, shaking hands) with an infected person.
By touching surfaces that the virus has landed on, then touching your eyes, mouth, or nose before washing your hands. (Not thought to spread easily by this method.)
COVID-19 enters your body through your mouth, nose or eyes (directly from the airborne droplets or from transfer of the virus from your hands to your face). The virus travels to the back of your nasal passages and mucous membrane in the back of your throat. It attaches to cells there, begins to multiply and moves into lung tissue. From there, the virus can spread to other body tissues.
Governments, health agencies, researchers and healthcare providers are all working together to develop policies and procedures to limit the spread of this virus both globally and from individual to individual.
