Recently, the Delta variant virus has been raging in many places. Even the mainland of China, which has always been very careful about epidemic prevention, has recently been "broken" by the variant virus and entered the community.
Following the outbreak of community transmission of the Delta variant in Guangzhou in May, community infections began in Nanjing in late last month.
However, the difference is that the Nanjing epidemic quickly spread to more than a dozen provinces and cities across the country, and it has not been completely "docked" yet.
And this Tuesday (3rd), the epidemic spread to Macau. Four people from a family with a history of travel to the Mainland were all diagnosed and it is estimated to have spread in the community. This is the first local transmission in Macau more than a year after clearing zero.
The breakthrough comes from relaxation of vigilance
The origin of the epidemic and its spread were caused by negligence.
According to the survey results, the mutant virus entered the community from Nanjing Lukou International Airport.
It is estimated that the poison has penetrated into the community because the cabin cleaners in charge of cleaning the cabin of the CA910 flight from Russia have irregular protection and elution, causing individual personnel to be infected and spreading among cleaners.
The outsourcing company to which the cleaner belongs did not strictly distinguish between the cleaners for international and domestic flights. As a result, other airport staff who were also responsible for the domestic garbage cleaning were also infected.
Unlike the Guangzhou epidemic in May, the Nanjing epidemic broke out at the airport and can quickly spread across provinces through domestic flights or other major transportation. Therefore, the epidemic quickly spread to many provinces and cities.
After the cabin cleaner was infected, other airport staff were recruited because of contact with the cleaner or the contaminated environment.

As for the latest outbreak in Macau, the couple in a family of four who were diagnosed had traveled to Guangdong, while their daughter had traveled to Shaanxi to study. The source should almost come from the mainland.
However, Macau also has more time for the virus to spread in the community due to human negligence.
The boy in the confirmed family visited the emergency department of Earls General Hospital from July 28th to 29th. It was suspected that someone was negligent and failed to test the boy immediately, which caused the delay to be diagnosed until August 3.
Within a few days, the family has come into contact with many other people, greatly increasing the degree of community transmission.
Responding to the epidemic early
From these examples, it can be seen that no matter how rigorous the epidemic prevention measures usually seem, as long as someone is lax, the epidemic prevention may be "broken" immediately.
Judging from the experience of the epidemic in the Mainland and Macau, early and strict control measures are crucial to controlling the epidemic. Once slackened, large-scale community infections may occur again.
On the same Tuesday (3rd), Hong Kong notified a 43-year-old construction worker of the initial diagnosis. Although the virus was low and the second review was negative, he was tested for antibodies, which clearly shows that Hong Kong still has a certain risk.
The government would rather take strict measures to deal with the risk of the epidemic first, and then relax after confirming that the risk has decreased, so as to avoid more serious consequences and even restart anti-epidemic measures such as lockdowns.

Another issue worth considering is that human negligence is difficult to completely avoid, and tactics that rely solely on external defense input cannot last forever.
Although this wave of epidemics in the Mainland has spread to many provinces and cities, the traceability work is better, and many cities have launched large-scale testing, and the epidemic is relatively under control.
Moreover, most of the confirmed patients have been vaccinated. Although the diagnosis cannot be completely prevented, the infected persons are mainly mild and asymptomatic, indicating that the vaccine's effect is still worthy of recognition.
This situation is significantly different from the outbreak of community infection in Taiwan from the end of April to the beginning of May.
Taiwan only attaches importance to external investigations, but its ability to control internal transmission is very weak. Detection capabilities, admissions and treatment capabilities, and even vaccination cannot keep up. As a result, the epidemic broke out. As a result, the entire Taiwan entered the third level of alert, and the death rate was once urgent. increase.
The epidemic is changeable, although it can be fully grasped.
Therefore, in addition to the "external defense import", Hong Kong must spend more time on the meticulous operation of vaccination and internal control of the epidemic in order to cope with the constantly updated status.

Increase the vaccination rate and control the epidemic. All walks of life should actively cooperate with female housekeepers to prevent the epidemic. Why is it difficult to prevent hotels?
Political leaders must understand that the responsible variant of the virus attacking communities to prevent spreading depends on vaccines
