Since April 9, Harbin City, Heilongjiang Province has had 2 new confirmed local cases of COVID-19 and 23 new local asymptomatic infections.
Within two days, 2 people were diagnosed and 3 were asymptomatic infections.
The source of infection was a mystery for a while.
Among them, on April 9, there was a new locally confirmed case in Harbin. The patient Guo Mouming reported that he had no history of traveling to Wuhan and surrounding areas, or other communities with reported cases; it was impossible to determine whether he had close contact with people with fever, cough and other symptoms, confirmed cases, or mild cases.
In addition, Wang Mouling, his girlfriend who had close contact with the confirmed case Guo Mouming, Wang Mouling's daughter Cao, and Cao's boyfriend Li, were all diagnosed as asymptomatic COVID-19 infections on April 9.
The patient did not cooperate with the epidemic investigation. The police filed a case to find out the truth.
Because the confirmed patient Guo Mouming and the asymptomatic infected person Wang Mouling did not cooperate with the epidemic investigation, it brought great difficulties to trace the source of infection and identify close contacts. Harbin City The public security organs immediately intervened and launched an investigation. Now, according to a joint investigation by the Harbin Municipal Center for Disease Control and Prevention and the Public Security Investigation Agency, Wang Mouling’s daughter Cao may have been exposed to the environment contaminated by people entering Harbin from abroad and became ill, which in turn led to clusters of infections among family members.
Previously infected persons imported from abroad may be the source of infection
Cao and Han are upstairs and downstairs neighbors. Han arrived in Harbin from the United States on March 19 and was quarantined at home for observation. During this period, both parties lived here together. Han's nucleic acid test on March 31 was negative, and the antibody test IgM and IgG were both negative. The nucleic acid test on April 3 was negative, and he was released from home isolation. After Guo's illness was diagnosed, the Health and Medical Commission conducted a traceability analysis and found that Cao and Han were possibly infected. Therefore, the Health and Medical Commission conducted two antibody tests on Han again on April 10 and 11. Among the tests, all IgM were negative and all IgG were positive, indicating that the patient had been infected with COVID-19. After on-site simulation investigation and analysis, Han and Cao lived together in a potentially polluted environment and had the conditions for infection.
A total of 456 close contacts have been traced, and they have all been quarantined.
As of 3 p.m. on the 11th, 456 close contacts have been traced, including 155 people under centralized isolation and medical observation and 301 people under home isolation and medical observation. At the same time, measures such as closed control and disinfection have also been adopted for the involved residential community units and relevant activity venues.
Local cases have appeared continuously in Heilongjiang and Guangdong
Recently, our country has been facing greater pressure from overseas imports, and local epidemic prevention efforts cannot be relaxed. After having no new local cases in the province for 29 consecutive days, Heilongjiang found new local cases for two consecutive days on April 9 and 10. In addition, from April 7 to April 10, new local cases have appeared in Guangdong Province for four consecutive days.
Another cluster of cases appears. National Health Commission: Don’t get together, gather less!
html On April 11, Mi Feng, spokesperson of the National Health and Medical Commission, said that clusters of cases have appeared in some provinces. It is recommended not to gather in groups and gather as little as possible!
In addition, during extraordinary times, everyone has the responsibility to proactively report their own information. Over a period of time, there have been numerous incidents of underreporting that have led to tragedies. Concealing a report not only violates laws and regulations, but is also irresponsible for the health of yourself and your family and friends, so we must not take any chances.
