According to Singapore’s “Joint Morning Post” reported on March 2, Singapore researchers in the local new coronary pneumonia patients found that the initial symptoms of the patient is mild, but it is the body’s largest amount of virus, as the symptoms develop the virus gradually decreased, which means that the amount of the virus in the patient and the severity of symptoms is not positively correlated.
The Director of the National Centre for Infectious Diseases in Singapore, Mr Leung Yu-xin, pointed out that patients who are infected with the new coronavirus usually develop mild symptoms such as cough and fever before worsening to pneumonia, but when the patient develops pneumonia, the amount of virus in the body has decreased significantly.
Chen Zhuquan, Chief Health Scientist of the Ministry of Health of Singapore, was the Director of Medicine of the Ministry of Health of Singapore during the Severe Acute Respiratory Syndrome (SARS) outbreak. He points out that this is the opposite of SARS, which produces more viruses in patients as the disease worsens. The new coronary pneumonia is more like influenza, with a higher level of virus in the body when the patient’s symptoms are mild.
Does a high level of viruses mean high infectiousness? ‘This will require more research to be determined, ‘ Mr. Liang said. The amount of viral genes detected by polymerase chain reactions, but it is impossible to distinguish between live and dead viruses, and only live viruses can replicate themselves and be contagious.
Regarding whether asymptomatic infections will spread the virus, Liang Haonan, infectious disease consultant at Mount Elizabeth Hospital in Singapore, believes that there are many viruses in the patient’s body, and if there are no symptoms such as cough, the virus will remain in the body in general.
Chen said the virus is mainly transmitted by droplets when coughing or sneezing, and that asymptomatic infections are not transmitted in the community unless they are spreading by sharing food with their families or making close physical contact.
Liang Yuxin also pointed out that it is now possible to find the link between most cases in the local area, if the spread of the new coronavirus mainly from asymptomatic infections, then it is difficult to find these links.
The researchers called on the public to wear masks and get timely visits, even if they experience mild symptoms.
