1)what are the sources of coronavirus ?
2)how do experts believe that coronavirus is transmitted?
Answers
Answer:
Explanation:
a)The source of the coronavirus is believed to be a "wet market" in Wuhan which sold both dead and live animals including fish and birds. Such markets pose a heightened risk of viruses jumping from animals to humans because hygiene standards are difficult to maintain if live animals are being kept and butchered on site. Typically, they are also densely packed allowing disease to spread from species to species.the animal source of Covid-19 has not yet been identified, but the original host is thought to be bats. Bats were not sold at the Wuhan market but may have infected live chickens or other animals sold there. Bats are host to a wide range of zoonotic viruses including Ebola, HIV and rabies.
Answer:
A coronavirus is a virus that is found in animals and rarely can be transmitted from animals to humans and then spread person to person.
symptoms may include:
fever
cough
shortness of breath
Those with weakened immune systems may develop more serious symptoms, like pneumonia or bronchitis.
When people with COVID-19 breathe out or cough, they expel tiny droplets that contain the virus. These droplets can enter the mouth or nose of someone without the virus, causing an infection to occur. The most common way that this illness spreads is through close contact with someone who has the infection. Infection is likely if the person then touches their nose, eyes, or mouth.
the research is still ongoing. There may also be other ways that the new coronavirus can spread.
