Chinese health experts warn that the transmission of nCoV between people becomes aggravated by ineffective isolation.

Speaking at a press conference yesterday in Guangzhou City, Guangdong Province, Chung Nam Son, a prominent epidemiologist, a Chinese government's medical adviser, said despite his own efforts. In Wuhan, in response to the Covid-19 epidemic, there are two issues that remain unresolved: isolating patients from healthy people and separating corona-infected patients from ordinary flu patients.

Not only does this make human-to-human transmission possible, but the spread of ordinary flu viruses is also worsening with the increasing number of people with fever at Wuhan hospitals, said Professor Yang Chiem Thu, a specialist Biologist at Wuhan University.

Yang said many hospitals in Wuhan could not check the pathogens of patients with fever due to other viruses, causing the viruses to spread.

"The spread of flu from person to person has exacerbated the situation of nCoV infection in Wuhan," Yang said, explaining that screening for Covid-19 patients becomes more difficult.

The shortage of medical personnel in the early stages of the outbreak was also a cause for the rapid spread of the virus from person to person, according to an unnamed labor in Wuhan. He said many patients could only stay home before being confirmed to be infected with nCoV, increasing the risk of F2 infection.

Hubei is strengthening its quarantine measures after replacing some high-ranking officials who are criticized for being negligent and weak in dealing with Covid-19. The provincial government has banned people from leaving homes, blockade 24-hour residential communities, and control the identities of people who buy flu drugs at drug stores. Meanwhile, the Wuhan city government has deployed a force of volunteers to knock on the doors of homes to track down suspected nCoV infections and force testing.

However, experts warn that these measures cannot prevent people who are likely to be infected in the first place or prevent them from infecting others. Mr. Chung proposed the Wuhan government to focus on solving these two problems. Wuhan accounts for 80% of Covid-19 patients and 90% of deaths, he said, emphasizing that the city remains the key in the fight against the epidemic, as the number of cases outside Hubei Province is declining.

Yang also asked Wuhan hospitals to identify the pathogens of fever patients and separate them from nCoV-infected patients to minimize the risk of spread. The situation of human-to-human transmission makes Wuhan face many more challenges, with too many patients and high number of deaths.

This morning, China recorded 137 more deaths and 1,749 new infections, bringing the number of deaths in the mainland to 2004 and the number of cases up to 74,185. In particular, Wuhan City recorded 1,660 new infections and 116 deaths.

A Wuhan resident, Chen, said that inadequate screening of nCoV patients and the imposition of blockade too late led to the spread of the virus.

"Our community just organized a collective purchase of basic supplies today, after a complete blockade. A few days ago, I heard that people still went to the supermarket recently, leading to a large gathering of people." Ms. Chen said. "Local governments act too slowly, missing the best opportunity to contain the epidemic."

Qian Yuankun, the deputy secretary of the Hubei Party Committee, admitted at a press conference yesterday in Wuhan that the problems of messy treatment, late treatment and bed shortage in some parts of the province made the situation of Some patients are aggravated. He urged speeding up hospitalization and treatment for patients. Wuhan government said it would build 10 more field hospitals, providing 11,465 beds for nCoV patients.
