As we all know, new coronavirus research will use animals such as mice, which means that mice and other animals can carry the new coronavirus
.
Therefore, hamsters belonging to the same rodent species may also be infected with the new coronavirus
New coronavirus research will use animals such as mice, which means that mice and other animals can carry the new coronavirus
Recently, a staff member of a pet store in Hong Kong was infected with the new crown, and the preliminary evidence chain showed that it was infected by hamsters in the pet store
.
This chain of transmission has resulted in the infection of 3 people
Since this conclusion is too sensitive, more evidence is needed on the transition of the new coronavirus from animals to humans
.
It is understood that the hamsters in the pet store were imported from the Netherlands, and the virus infected by the employee was sequenced, which is consistent with the genome sequence of the hamsters imported from the Netherlands.
The possibility of mutual transmission between humans and hamsters cannot be ruled out
.
The Hong Kong case may be the first in the world as no laboratory has confirmed human-to-animal transmission of hamsters before
.
The clerk was infected with the Delta strain, and the source of the transmission is not yet clear
.
From this the current conclusion points to hamsters from the Netherlands
On December 19 last year, three new cases were confirmed in Hong Kong, when the infection status of one case was unknown
.
On December 19 last year, 3 new cases were confirmed in Hong Kong, when one case was unknown.
As of Monday, the total number of COVID-19 cases in Hong Kong stood at 13,048, with 213 related deaths
.
If the transmission chain from animals to people is confirmed this time, the pressure on Hong Kong's epidemic prevention and control will further increase
As a result, the infection incident has attracted the attention of the Hong Kong authorities, who believe that there is a possibility of hamster infection between humans and animals
.
Hong Kong's Agriculture, Fisheries and Conservation Department is handling small animals at the pet store in Causeway Bay, the warehouse in Tai Po, and other pet stores in Hong Kong that sell hamsters.
Customers are also required to hand in hamsters purchased before December 22
.
It is estimated that 2,000 small animals will be handled humanely
All pet shops in Hong Kong that can sell hamsters will be closed, and the quarantine requirements for imported pets will be tightened, and new coronavirus testing will be strictly carried out
.
Relevant departments in Hong Kong also issued a notice warning the public not to abandon hamsters at will, and hand them over to the Agriculture, Fisheries and Conservation Department for unified treatment; do not kiss hamsters, maintain good personal hygiene, and actively receive testing for any suspected symptoms or abnormalities
.
In fact, the risk of cross-species infection of the new coronavirus has always existed
.
It is reported that five pigeons tested positive after a woman arrived at the hotel from Pakistan in recent days
.
However , there have been many questions about whether the new coronavirus can directly infect people from animals
Whether pigeons and pigeons can directly infect people with the new coronavirus from animals, there have always been many doubts about whether the new coronavirus can directly infect people from animals.
Animals susceptible to COVID-19
Covid-19 susceptible animalsHowever, many animals have also become the target of the new crown virus attack.
In addition to cats such as cats and ligers, minks, deer, rabbits and other animals have been included in the new crown susceptible list

Cats such as ligers, minks, deer, rabbits and other animals have been included in the list of new crown susceptibility
In 2020, the Netherlands has culled minks on a large scale, because of the occurrence of positive samples detected by local farms, 66 of 97 subjects were positive, and it initially showed signs of virus mutation in minks
.
France, Spain, and Denmark have also carried out mink culling campaigns, resulting in huge economic losses and waste of resources
In 2021, an article by Gao Fu, academician of the Chinese Academy of Sciences and director of the Chinese Center for Disease Control and Prevention, Perspectives: COVID-19 Expands Its Territories from Humans to Animals pointed out that the animal host of the new crown has a tendency to expand
.
However, no clear chain of evidence has been found: the new coronavirus can directly infect people from animals
.
Therefore, the claim that this case in Hong Kong is from hamster to human needs more reliable evidence and analysis
.
