Kuwait announced on Wednesday there were two new coronavirus cases in the country, with the infections occurring among people returning from Iran.
The new cases bring the total number to 11 in Kuwait, according to a statement by the health ministry.
The disease is believed to have originated in a market selling wildlife in the Chinese city of Wuhan late last year and has infected about 80,000 people and killed more than 2,700, the vast majority in China.
Adding to a growing sense that a rapid spread of the virus in more places is inevitable, a top World Health Organization (WHO) official urged that preparations be made now.
In the United States, the U.S. Centers for Disease Control and Prevention also urged Americans to prepare, saying that while the immediate risk there was low, the global situation suggested a pandemic was likely.
"It's not a question of if. It's a question of when and how many people will be infected," the CDC's principal deputy director, Anne Schuchat, said on Tuesday.
The United States has reported 57 cases of the virus.
Dr Bruce Aylward, head of a joint WHO-Chinese mission on the outbreak, told reporters on his return to Geneva that preparations should not wait.
"Think the virus is going to show up tomorrow. If you don't think that way, you're not going to be ready," he said.
Aylward said China's "extraordinary mobilisation" to handle the outbreak showed how an aggressive public health policy, including large quarantines, could curb its spread.
The head of the World Health Organization-led team in the central Chinese city of Wuhan probing the origins of COVID-19 said on Tuesday that cold chain transmission of the virus is a possibility and warrants further investigation.
Kuwait has suspended all flights from India until further notice, Bahrain has updated International arrival procedures for passengers from India. Germany is sharply restricting travel from India and Iran has banned all flights to and from India and Pakistan.
The group was driven to the Jinyintan Hospital, one of the city’s first to deal with patients in early 2020 suffering from a then-unknown virus, as the horrors of the virus emerged in the central Chinese city.
The mission, delayed by China and weighed down by political baggage, has a remit to explore how the virus jumped from animal to human. Experts say the Huanan market still plays a role in tracing the origins of the virus, since the first cluster of cases was identified there.
The fighting in Mindat, Chin state, underlines the growing chaos in Myanmar as the junta struggles to impose authority in the face of daily protests, strikes and sabotage attacks after overthrowing elected leader Aung San Suu Kyi.
Plans call for a rover to stay in the lander for a few days of diagnostic tests before rolling down a ramp to explore an area of Mars known as Utopia Planitia. It will join an American rover that arrived at the red planet in February.
Violent winds of more than 100 kilometres per hour (60 miles per hour) blasted the central city of Wuhan on Friday night. Six people died and more than 200 were injured, authorities said, adding that around 30 homes had collapsed.
