1st case of coronavirus reported in U.S.; what you need to know about the virus
The U.S. has its first case of a new virus that was found only last month in China. A U.S. citizen who recently returned from a trip to central China has been diagnosed with the new virus.
The man returned to the Seattle area in the middle of last week after traveling to the Wuhan area, where the outbreak began. The man is in his 30s and is in good condition at a hospital in Everett, outside Seattle. The virus has sparked an outbreak in Asia and stringent monitoring around the world. Late last week, U.S. health officials began screening passengers from central China at U.S. airports.
Here’s what you should know about the illnesses:
WHAT IS THE DISEASE?
Scientists have identified it as a new kind of coronavirus. There are many known types of coronaviruses. Some cause the common cold. Others found in bats, camels and other animals have evolved into more severe illnesses such as SARS (severe acute respiratory syndrome) or MERS (Middle East respiratory syndrome).
WHY IS IT CALLED A CORONAVIRUS?
Corona comes from Latin and refers to crowns or halos. Under a microscope, these viruses resemble crowns or halos.
WHEN WAS THE NEW VIRUS FOUND?
The outbreak started late last month in the city of Wuhan in central China, apparently at a food market.
HOW MANY PEOPLE HAVE IT AND HOW WIDESPREAD IS IT?
About 300 cases have been identified. There are about 260 cases in Wuhan, according to Chinese officials. Cases in other Chinese cities, including Beijing and Shanghai, total around 30. They were reported with the onset of an annual travel rush for the Lunar New Year holiday. Many Chinese travel abroad for the holiday and a few cases have been confirmed outside the mainland — in South Korea, Japan, Thailand, Taiwan and now the U.S. That travel rush is expected to spread the disease more widely.
WHAT ARE THE SYMPTOMS?
Common symptoms include a runny nose, headache, cough and fever. Shortness of breath, chills and body aches are associated with more dangerous kinds of coronavirus, according to the U.S. Centers for Disease Control and Prevention.
HOW ARE CORONAVIRUSES SPREAD?
Many coronaviruses can spread through coughing or sneezing, or by touching an infected person. Initially, authorities in China said there was no evidence of human-to-human transmission in the present outbreak. But an expert panel has concluded there have been at least a few cases of people catching it from others, raising the possibility it could spread more widely.
COULD IT BE AS BAD AS SARS?
So far, the virus appears less dangerous and infectious than SARS, which also started in China and killed about 800 people. As of Tuesday, six deaths had been reported, all in Wuhan. Viruses can mutate into more dangerous and contagious forms, and it’s too early to say what will happen with this one.
