Can high temperature days "kill" virus?

From July 16th, Shanghai has officially "entered". It is expected that the "three volts" this year will last 40 days and will continue until August 24. It is really a "long standby".

Earlier, Shanghai has experienced 40 degrees of high temperature for many days. But can high temperature "kill" new crown virus? How should citizens do well?

Can the virus survive in seasonal changes?

Zhang Ziqiang, director of the Department of Infectious Department of Tongji Hospital affiliated to Tongji University, said that in the early stage of the new crown epidemic, the study of the virus showed that in general, the new crown virus took 56 ° C for 30 minutes. However, some studies have shown that for samples with high virus content, the above conditions may still be difficult to fully activate the virus.

"At present, the spread of the new crown virus does not show obvious seasonality. Obviously, the temperature in summer in summer is not enough to survive the new crown virus. In the past, people speculated that with the arrival of summer, the heat wave can prevent the spread of the new crown virus. This guess is currently looking at it. It is not established. In addition, from the perspective of the global new crown epidemic, climate and other climate factors have no significant impact on the spread of the new crown virus. "Zhang Ziqiang said that it is not realistic to expect the weather to heat up the new crown virus.

In the hot summer, cold chain foods are very popular, and the amount of cold chain fresh food distribution in meat, poultry, aquatic products, and fruits has increased dramatically. The high temperature "killing" new crown virus, but the low temperature environment is more conducive to the survival of the new crown virus.

Although compared with the dissection of the respiratory tract droplets, the transmission of air solution, and close contact, the possibility of infection with the new coronary virus infected by contacting cold chain food and express parcels cannot be ignored.

Citizens must not have relaxing psychology. We must increase their vigilance. When buying fresh food and receiving express delivery, especially "Haitao" goods, personal protection should be done to avoid possible potential risks.

Keep in mind the "new three -piece set" without relaxing

The temperature is not the decisive factor of "killing" the new coronary virus. It is still the focus of epidemic prevention. In daily life, citizens still need to adhere to the "three -piece set" and protect the "five more", especially wearing a mask and wash their hands.

However, in public, some citizens can still find problems such as exposed nose, mouth, and unprepared wear when we wear masks.

To this end, the citizens are particularly reminded that they should not loosen their vigilance and take the mask as a decoration. Don't "drop the chain" at a critical moment.

Wearing a mask is not cope. In particular, under the conditions of public transportation, closed places, personnel dense places, and shopping mall ordering, shopping, and receiving courier takeaway, we should wear a mask.

When wearing a mask, you should distinguish the positive and opposite, cover your nose, nose and chin. The nose clips must be compacted. Dirty, deformation, damage, and odor need to be replaced in time. The continuous wearing time does not exceed 8 hours.

However, the weather has been hot recently. For example, if the citizens have symptoms such as chest tightness and shortness of breath and difficulty breathing after wearing masks for a long time, they choose to be empty places nearby and take off the masks briefly to ensure personal physical condition.
