Answer 1

History

Experts say SARS-CoV-2 originated in bats. That’s also how the coronaviruses behind Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) got started.

SARS-CoV-2 made the jump to humans at one of Wuhan’s open-air “wet markets.” They’re where customers buy fresh meat and fish, including animals that are killed on the spot.

Causes

Coronaviruses are common in certain species of animals, such as cattle and camels. Although the transmission of coronaviruses from animals to humans is rare, this new strain likely came from bats, though one study suggests pangolins may be the origin.

However, it remains unclear exactly how the virus first spread to humans.

Symptoms

Signs and symptoms of coronavirus disease 2019 (COVID-19) may appear two to 14 days after exposure. This time after exposure and before having symptoms is called the incubation period. Common signs and symptoms can include:

• Fever
• Cough
• Tiredness

Other symptoms can include:

• Shortness of breath or difficulty breathing
• Muscle aches
• Chills
• Sore throat
• Loss of taste or smell
• Headache
• Chest pain

Prevention

To prevent the spread of COVID-19:

1. Clean your hands often.
2. Use soap and water, or an alcohol-based hand rub.
3. Maintain a safe distance from anyone who is coughing or sneezing.
4. Don’t touch your eyes, nose or mouth.
5. Cover your nose and mouth with your bent elbow or a tissue when you cough or sneeze.
6. Stay home if you feel unwell.
7. If you have a fever, cough and difficulty breathing, seek medical attention. Call in advance.
8. Follow the directions of your local health authority.
