9 Zhong Nanshan's Latest Points on COVID-19 New Coronary Pneumonia
According to the latest WHO data, there have been more than
3.4 million confirmed cases of new coronary pneumonia worldwide. The epidemic
prevention and control situation is still grim. How should more than 1.4
million overseas students in China protect themselves? How to minimize the
impact of the epidemic on academics?
On the evening of May 4, the Ministry of Foreign Affairs and the National Health and Welfare Commission jointly invited Zhong Nanshan, an academician of the Chinese Academy of Engineering, to answer questions for foreign students in the United States, Russia and other areas where epidemics are most common. More than an hour of connection, a lot of information!
1. Do not approve of group immunization, because many people have to be sacrificed
In the live broadcast connection, Zhong Nanshan said that he did not approve of "group immunization" because it would cost many people to achieve "group immunization". Zhong Nanshan said that there are reports in Europe that 20% of people have antibodies and 25% in some countries, but it is far from the so-called group immunity. To achieve group immunity, generally 60% -70% of people have this possibility after infection, and it is still far from being achieved.
Therefore, Zhong Nanshan said that he did not approve of this method because too many people were sacrificed. "We have many ways. We can prevent and protect, and we will buy time and make vaccines."
2. The infectivity of the new coronavirus is not expected
Zhong Nanshan introduced that the infectivity of the new coronavirus is unexpected. From the perspective of infectivity index, the general flu is 1, SARS is close to 2, the Middle East respiratory syndrome is 1.5, and the new coronary pneumonia is 3.
3. At present, there is no evidence that mosquito bites can transmit new coronavirus
Academician Zhong Nanshan said that in general, the survival
rate and activity rate of the virus in a high temperature environment are
relatively poor.
When summer comes, the virus activity will decline, and the
high temperature is not good for the virus activity. However, the ultraviolet
rays in nature are not strong enough to be sterilized, and it is impossible to
rely solely on high temperature to block the spread of the virus.
He mentioned that mosquito bites can infect many diseases, such as malaria and dengue fever, which are more common in Africa. But so far, there is no evidence that the new coronavirus can spread through mosquitoes.
4. Strong winds and blizzards will not accelerate the spread of the virus
Zhong Nanshan said that the virus must be attached to something to spread, the most prominent is spread through droplets. In the event of snowfall or strong winds, the spread of the virus will not only accelerate but also slow down. The wind virus is quickly diluted, and will not spread if it does not reach a certain concentration in the air.
5. There is evidence to prove that Lianhua Qingwen is effective
Zhong Nanshan reminds foreign students that if they have a fever, they should drink plenty of water and eat some medicines taken in the past, such as Baifuling, ibuprofen, and Lianhua Qingwen.
He specifically mentioned that just after an experiment was
done, there is sufficient evidence to prove that Lianhua Qingwen has a certain
effect. In vitro experiments found that Lianhua Qingwen Capsule has some
inhibitory effects on the virus.
Although it is very weak, the benefit is that
it has a good repair effect on cell damage and inflammation caused by the
virus.
More than 80% of the patients are ordinary new crown patients. Lianhua Qingwen Capsule is more suitable for ordinary new crown pneumonia patients.
6. Is there any sequelae in the new coronary pneumonia?
Zhong Nanshan said that according to his observation, the
patient recovered well after being discharged from the hospital. As long as
there is no underlying disease, the recovery will be very fast.
Even if there
are some basic diseases, according to his observation, it is still better than
SARS. Zhong Nanshan said that in SARS 17 years ago, some patients still had
pulmonary fibrosis half a year to a year later.
The lung fibrosis of patients
with new coronary pneumonia is not too heavy and looks reversible.
"We have performed lung function tests on more than 100 patients and have not returned to normal levels, but it does not seem to be too damaging and will gradually recover, so the sequelae are not great.
7. What should we pay attention to in the lives of international students?
Zhong Nanshan suggestes:
i. Wear a mask for protection. Don't let people follow the cloud, and don't go into the countryside to follow the customs. In the past, many people had a different view of wearing masks in China. Now, some countries that were very opposed to wearing masks have started wearing masks. It was our correct approach that drove them.
ii. Many people live together, and pay attention to disinfection and hand washing when sharing public spaces such as toilets and kitchens.
8. Zhong Nanshan recalled his experience of studying abroad 41 years ago and talked about how to relieve stress
An international student asked that the pressure on foreign
students under the epidemic was generally very high. Zhong Nanshan recalled 41
his experience of studying in the UK and taught everyone how to relieve stress.
Zhong Nanshan said that he felt the same way at the time. He was lonely and
depressed. He also had heavy academic work and great pressure.
With the
outbreak of the global epidemic now, he particularly understands the feelings
of international students.
He encouraged young overseas students to take this
epidemic as a test of their own psychology, not only for physical protection,
but also for psychological protection.
Persevere in your studies and temper your willpower.
9. If you want to return to China, how to protect it?
Zhong Nanshan suggested:
i. If it is possible to do a nucleic acid test before
returning home, make sure that you are on the plane in the best condition.
The virus has an incubation period of three to seven days, up to a dozen hours on the plane, during which time it is unlikely that the infection will occur and symptoms will appear soon.
ii. Pay attention to protection, wear masks, and wash your hands.
iii. Come back for the test, even if it is positive, you don't have to panic, take a good rest and cooperate with the treatment.
