Thai authorities on Monday confirmed that a visitor from Wuhan, China, has been infected with a new coronavirus, the Centers for Disease Control (CDC) said yesterday, adding that the possibility of human-to-human transmission can not yet be ruled out.
There is no specific treatment for the new virus, but anti-virals are being considered.
The Wuhan Municipal Health Commission did not say in the statement whether the couple represented a human-to-human case.
Some of the other people diagnosed also refused to visit the market, the committee said. They added that the man worked at a local wholesale seafood market related to most of the patients, but his wife has not visited the place. The woman is now recovering, and officials continue to investigate the case.
Also, state-run media Beijing News previously reported that two patients were confirmed to be a mother and son, with the latter a poultry shop vendor at the market. But because the wife did not exhibit symptoms until days after her husband, it's also possible that he infected her.
Wuhan's health commission said on Wednesday that most of the patients diagnosed with the virus were male, and many were middle-aged or elderly. The World Health Organization and Chinese authorities are taking steps to ensure the disease does not spread further.
In total, it infected more than 8000 people in 26 countries.
Recently, officials reported the first "exported" case of the virus in Thailand.
Authorities in Banteay Meanchey province have stepped up checks at the Poipet border with Aranyaprathet district of Sa Kaeo following reports that a Chinese tourist to Thailand had been confirmed to be infected with a new pneumonia-like disease.
Richard Brow, the agency's representative in Thailand, said anyone with a fever and cough who had spent time in Wuhan should get checked out by a health worker.
Hong Kong medical experts made the announcement after returning from Wuhan. There have since been no new cases or deaths, Wuhan health authorities said on Tuesday.
