On the evening of June 18, Professor Ceng Guang, the chief pre-school epidemiologist of China CDC, answered some important questions about the epidemic in a live broadcast.
Will there be another epidemic in the future or is it a high probability event?
At present, the epidemic situation in Beijing should be optimistic and cautious. Only when the last epidemic focus is found and controlled will it be a complete victory.
It may take three years to fully understand a virus, and then observe the onset cycle of the virus. It may take ten or even twenty years. Now we have had two outbreaks in a short period of six months. Another outbreak in the future is still a high-probability event. Normalized prevention and control will become a habit in the future and cannot be very optimistic and relaxed.
The chopping board, kitchen knife and door handle in the new place have been polluted.
In the treatment of meat products or seafood, there are no strict hygiene measures in the farmers market. This time it was found that the chopping board, kitchen knife, door handle, etc. in the new place had been contaminated, which provided conditions for the infection of the virus. In addition, the improper management of small restaurants has also led to insecurity. I hope the loopholes exposed this time can be corrected and strengthened in future management.
More than a dozen countries are interested in the vaccine phase III clinic to be carried out in epidemic areas.
China must be the first echelon in the research and development of vaccines worldwide. The results of the first and second phase of clinical trials of the vaccine are good and fully confirm the safety and effectiveness of the vaccine. Phase III clinical trials will be conducted immediately, but phase III clinical trials will be conducted in epidemic areas and are still being evaluated. More than a dozen countries are interested in it.
We haven't done the third phase yet. Do we need to produce a batch of vaccines? I think it is necessary to have a unified allocation, a unified argument, a proper reserve and use it when necessary. For the general public, it is still impossible to use the vaccine quickly, because the Phase III clinical trial will continue according to the rules, and large-scale application will not be possible until the test is completed and the safety and effectiveness of the vaccine are finally confirmed.
At present, there are fewer severe and critical patients in this epidemic situation.
When an epidemic occurs, reproduction will not be affected, unnecessary control will be minimized, and people are used to finding and solving problems in the dynamic. At present, there are fewer patients with severe and critical diseases in this epidemic, which has not caused a run on medical resources, and also indicates that it has been controlled at an early stage.
Now it is still necessary to focus on key areas such as nursing homes, geriatric wards of hospitals, detention houses, etc. We are full of confidence in the control of the epidemic, at the same time, we are cautious and obey the arrangement.
