Those traveling from Wuhan showing signs of fever, coughing or difficulty in breathing should visit the nearest medical facility, the ministry said.
Drosten, one of the co-discoverers of SARS, said the two viruses are so closely related that laboratories that have control samples for SARS in stock can use it to diagnose the new virus, thereby shortening the time needed to Functioning test.
A few of the other individuals identified also refused to visit the market, the commission said.
But since cases have cropped up without any exposure to the food market, there is reason to believe it can be transferred between humans.
The woman who tested positive is in good health now, according to Dr. Suthat Chottanapund, a senior official of the disease control department from Thailand's health ministry.
"Investigations to establish whether the suspect case is linked to the Wuhan pneumonia cluster are ongoing", said MOH. She said she wanted to do some sightseeing after she is discharged, he said.
There may have been limited human-to-human transmission of a new coronavirus in China within families, and it is possible there could be a wider outbreak including Nepal, the World Health Organization (WHO) said.
So far, no transmission of the virus after the Wuhan human-to-human has been confirmed, but the Health Commission said the possibility "cannot be excluded".
The new found coronavirus can have various symptoms ranging from common cold to even major infections such as Middle East Respiratory Syndrome (MERS) or Severe Acute Respiratory Syndrome (SARS). No additional cases have been detected since January 3 in China.
The news came just ahead of the lunar new year, when many Chinese travel. Jeremy Farrar, a British-based infectious disease specialist and director of the Wellcome Trust global health charity, said news of a case in Japan was "extremely concerning".
