The new figures from China’s Health Commission on Wednesday showed that 65 people died on Tuesday and that 3,887 more people had been infected. So far, 24,324 people have been infected.

Health experts say the death toll is likely to rise because of the large number of infections. The mortality rate of the coronavirus, about 2 percent so far, appears to be far lower than SARS, which has a mortality rate of about 10 percent.

Experts warn they still lack full data to say definitively how lethal the new coronavirus is. Many residents in Wuhan believe the death toll is much higher than the official tally because people with flulike symptoms are being turned away by overstretched hospitals. The health care system there is so overwhelmed that many cases are not diagnosed because of a shortage of testing kits.

The number of people recovering from the virus is also rising, suggesting that the treatment plan is working. On Tuesday, 262 people left the hospitals. The number of new suspected cases has dropped for two days in a row. Officials said they were tracking 3,971 new suspected cases, compared with 5,173 cases the day before.

On Tuesday, health officials released details of the deaths so far, saying that two-thirds of them were men. More than 80 percent were over 60 years old, and they typically had pre-existing health conditions such as cardiovascular diseases or diabetes.
