The death toll from the COVID-19 outbreak rose again on Tuesday but Chinese and international health officials sought to calm global nerves, citing a study showing that most cases are mild and warning against excessive measures to contain the epidemic.
Nearly 1,900 people have died and more than 72,000 others infected by the virus in China, with hundreds more cases in 25 countries.
The situation remains dire at the epicentre, with the director of a hospital in the central city of Wuhan becoming the seventh medical worker to succumb to the illness. But Chinese officials released a study showing most patients have mild cases of the illness, and the World Health Organization officials said the mortality rate was relatively low.
The epidemic has triggered panic-buying in Singapore and Hong Kong, concerns about cruise-ship travel and the postponement of trade fairs, sports competitions and cultural events in China and abroad.
The outbreak is threatening to put a dent in the global economy, with China paralysed by vast quarantine measures and major firms such as iPhone-maker Apple and mining giant BHP warning it could damage bottom lines.
Several countries have banned travellers from China and major airlines have suspended flights.
Authorities have placed about 56 million people in hard-hit central Hubei and its capital Wuhan under an unprecedented lockdown. Other cities far from the epicentre have restricted the movements of residents, with a 14-day self-quarantine for people returning to Beijing.
President Xi Jinping, in a phone call with British Prime Minister Boris Johnson, said China’s measures were achieving “visible progress”, according to state media.
'Less deadly' than SARS
The official death toll in China hit 1,868 on Tuesday after another 98 people died — most in Hubei and Wuhan, where the virus emerged in December.
Liu Zhiming, the director of Wuchang Hospital in Wuhan, became its latest victim, sparking an outpouring of grief online.
Earlier this month, the death of Wuhan doctor Li Wenliang — who had been punished by authorities for sounding the alarm about the virus in late December — triggered anger and calls for political reforms on social media.
Officials figures, meanwhile, showed there were nearly 1,900 new COVID-19 cases. New infections have been falling in the rest of the country for the past two weeks.

WHO chief Tedros Adhanom Ghebreyesus cautioned that it was too early to tell if the decline would continue.
A study among 72,000 confirmed, suspected and clinically diagnosed cases showed that 81% of patients had only mild infections. Those most at risk were the elderly, and people with underlying medical conditions.
The study released by China’s Centre for Disease Control and Prevention also showed that the death rate stood at 2.3%, falling below one per cent for people in their 30s and 40s.
Zhong Nanshan, a prominent expert with China's National Health Commission, told reporters that 85% of patients can improve “if they have good life support, treatment conditions, and nutrients”.
The research was cited by WHO officials, who said the COVID-19 illness was “less deadly” than its cousins, such as the Severe Acute Respiratory Syndrome (SARS) or the Middle East Respiratory Syndrome (MERS).
But it is higher than the mortality rate for the seasonal flu, at around 0.1% in the United States.

Michael Ryan, head of WHO’s health emergencies programme, said the outbreak was “very serious” and could grow, but stressed that outside Hubei the epidemic was “affecting a very, very tiny, tiny proportion of people”. There have been some 900 cases around the world, with five deaths.
Cruise concerns
Another 88 people tested positive for the virus on the quarantined Diamond Princess cruise ship off Japan, raising the number of infections to 542.
The U.S. repatriated more than 300 American passengers on Monday and Britain became the latest country to offer its citizens a way off the ship after similar plans by Canada, Australia, Hong Kong and South Korea.
Attention was also turning to the Westerdam , a cruise ship in Cambodia, where many of the 2,200 people aboard passengers were allowed to disembark after all initially received a clean bill of health.

An 83-year-old American woman was later diagnosed with the virus in Malaysia, raising concerns that other passengers might have been infected before flying to other countries.
The WHO rejected the suggestion that all cruises should be halted after hundreds of passengers were infected on one vessel off Japan.
“Measures should be taken proportional to the situation. Blanket measures may not help,” Mr. Tedros said.
