Câu hỏi: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
At the end of 2019, a new type of coronavirus started spreading China. This type of coronavirus is often called 2019-nCov, novel coronavirus, or COVID-19. It is believed that the virus was transmitted from animals to humans. Some of the first cases were diagnosed in people who had visited a market selling live seafood and animals. Unfortunately, when viruses are transmitted from animals to people, it can take scientists a lot of time before they can develop a vaccine or medicines to cure it.
Some of the symptoms of the coronavirus are fever, cough, runny nose, sore throat, headache, and trouble breathing. These symptoms are very much like those people have with a cold or the flu. The virus appears to spread mainly from person to person. The transmission occurs when someone comes into contact with an infected person. For example, a cough, sneeze or handshake could cause transmission. The spread may also be caused by coming into contact with something an infected person has touched and then touching your mouth, nose or eyes.
There is no specific vaccine or medication to cure the disease, but generally, symptoms will go away on their own. However, experts recommend seeking medical care early if symptoms feel worse than a standard cold. Doctors can relieve symptoms by prescribing pain or fever medication. As far as antibiotics are concerned, they are useless to treat coronavirus.
