Coronavirus updates LIVE: Trump blames China for ‘mass worldwide killing’, global cases pass 4.95 million

That’s problematic and differs with early reports that described Covid-19 manifesting as pneumonia, according to researchers in Japan.

“Most cases are milder and could have more transmission potential because patients might not seek medical attention,” said Takeshi Arashiro, a junior resident at the Asahi General Hospital in Chiba, just outside Tokyo.

Early reports described Covid-19 manifesting as pneumonia, “but most cases are milder and could have more transmission potential because patients might not seek medical attention,” said Arashiro, who is also a collaborating researcher with the Infectious Diseases Surveillance Center in the National Institute of Infectious Diseases in Tokyo.

The lower threshold for testing people for the coronavirus while the cruise ship was quarantined in Yokahama “created an opportunity to observe mild Covid-19 cases and monitor patient symptoms,” he said.

Understanding the disease pattern that coronavirus infection can cause is important for informing strategies for detecting and controlling it.

The high proportion of people who test positive for the virus and have only mild or no symptoms makes fever-screening travellers, for example, much less useful in detecting probable infections than was the case with the related coronavirus that caused severe acute respiratory syndrome 17 years ago.
