No Special Effect Medicine for COVID-19-Coronavirus in Current Time
At the
46th epidemic prevention and control news briefing held in Guangzhou today
(March 18), Zhong Nanshan, leader of the high-level expert group of the
National Health and Health Commission and an academician of the Chinese Academy
of Engineering, said that it is impossible to rely on collective immunization
to respond to the new coronary pneumonia epidemic. There is no evidence that a
new coronavirus infection can be immunized.
At the
same time, he believes that the source and the epidemic are not the same thing.
The outbreak of New Coronary Pneumonia occurred in Wuhan, which does not mean
that the source was Wuhan.
The epidemic occurred in China, and the source may
not necessarily be in China. "It's a scientific question. Before I figure
it out, it's irresponsible to make conclusions casually."
In
addition, Zhong Nanshan also expressed his views on the virus characteristics,
drug treatment, and prevention and control of outbreaks in foreign countries.
On collective immunity against COVID19
Can't rely
on collective immunization to solve problems, it seems.
Zhong
Nanshan believes that the problem cannot be solved by collective immunization.
Collective immunization should infect 70% of the population once, but there is
no evidence that any coronavirus will never get any more after a single
infection.
Therefore, producing effective vaccines is a very important task and
requires international cooperation.
Talk about drug treatment for COVID 19
There are
currently no specific drugs, and a summary of the use of chloroquine will be
published next week
He said
that until now, there is still no specific treatment for this virus. Once the
new coronary pneumonia has developed into a critical illness, treatment will be
very difficult. "We found some disease characteristics, but there is no
good solution."
Belgium Experiment in 2004 showed Chloroquine can kill coronaviruses
Zhong
Nanshan revealed that chloroquine is currently being tested to treat new
coronary pneumonia. "An experiment in Belgium in 2004 showed that
chloroquine can effectively kill coronaviruses. And chloroquine is an old drug
and very safe."
He said
that a summary of the use of chloroquine will be published next week.
"Currently, chloroquine has an average negative effect on the virus of
about 4 days, which is faster than ordinary drugs. But we need to summarize it
further because we have no comparative control or comparative
experiments."
"At
the same time, we are also conducting trials of redoxivir.
In addition, Chinese
medicine has a certain effect on reducing symptoms and accelerating recovery.
The results in the laboratory have been published, and the clinical effect is
currently being summarized." Zhong Nanshan said, overall.
In general,
although there is no specific method, there are already some methods to speed
up the recovery of the disease and prevent the development of critical illness.
On COVID 19 virus characteristics
Different mortality
rates due to different intervention methods in different countries
Zhong
Nanshan said that the new coronavirus is a brand-new virus that we have not
faced. It is more infectious than SARS and MERS, and has a very high mortality
rate compared to influenza. Worldwide, the mortality rate ranges from 7 percent
to a few percent, which is affected by different interventions by various
countries.
In terms
of transmission route, the new coronavirus is mainly transmitted through the
respiratory tract, but not only from the respiratory tract to the respiratory
tract, but also through pollutants and inhalation from pollutants, including
feces.
On the prevention and control of epidemic situation world wide
Controlling
from the source is the oldest and most effective.
Zhong
Nanshan pointed out that the outbreak will bring many problems, such as the
shortage of medical resources in Italy. "Controlling all infectious
diseases from the source is the oldest and most effective. All countries have
to do this, which is my opinion."
Europe is
now at the beginning of the first epidemic. Zhong Nanshan suggested that
prevention and control should be more active.
Don’t wait until the patient has
symptoms, and isolate the people in close contact as soon as possible to avoid
further expansion of the epidemic.
"My
point of view is that a confirmed case is found in one place, and close
contacts should be quarantined even if there are no symptoms.
Don't let him
spread it to others. Family members and contacts of people with symptoms should
go to check, don't wait, wait for the epidemic.
It's more difficult to get
bigger and bigger. "Zhong Nanshan said that if a country does not do
strong intervention, the new crown epidemic will not disappear. All countries
must act.
On China's National Defense Control Experience
Contain
areas with high incidence of epidemics, joint prevention and joint control in
other areas
Zhong
Nanshan said that the source and the epidemic situation are not the same thing.
"The epidemic
of New Coronary Pneumonia occurred in Wuhan, which does not mean that the
source is in Wuhan.
This is a scientific problem. Before we figure it out, it
is irresponsible to draw conclusions. The epidemic occurred in China, and the
source is not necessarily in China.
China has made a lot of progress. In
particular, there will be an answer to the virus's family and virus evolution
in the future (through research). "
Zhong
Nanshan said that China has learned how to prevent and control through practice,
that is, to take strong intervention.
"Highly infectious outbreaks are
exponential outbreaks, with an RO (transmission index) close to 3, which is
higher than diseases such as influenza.
In this case, the pressure in the
central area of the outbreak is reduced, allowing the spread of the disease
to slow down and let the central area not So passive is a very important
measure. "
He said
that China's experience lies in controlling upstream, enclosing areas where
epidemic outbreaks are common, and other areas doing joint defense and joint
control. At present, these measures have proved effective.
"The
core of joint defense and joint control lies in 'early protection'. Japan and South
Korea have done a good job, such as attending less meetings, staying at home,
and wearing more masks.
'Early discovery', seeing doctors if they are
uncomfortable.
'Early diagnosis', I come back from Wuhan Shortly afterwards,
CDC decentralized nucleic acid detection to the hospital, which is very useful
for early detection and early diagnosis. In some countries, the time is longer,
as long as 3 or 4 weeks. The world is not waiting for others; Isolation.
"Zhong Nanshan said.
Talking about COVID 19 vaccine development
China is
stepping up vaccine development in five directions.
Zhong
Nanshan said the epidemic situation is the most fundamental problem.
China's
current vaccine development has five directions:
One is a whole virus vaccine,
such as the 2009 H1N1 vaccine.
Second is a nucleic acid vaccine, the United States
is initially conducting safety tests on humans, and China is conducting the
first phase of clinical trials.
Also, third is carrier vaccine.
Then also, fourth is protein vaccine in
genetic engineering.
Also, fifth is influenza as a carrier vaccine.
He said
that the research and development of China's five vaccines are very tight.
"Guangdong is currently developing nucleic acid vaccines, doing animal
experiments, and also using adenovirus as a carrier vaccine. It is working day
and night, hoping to make great progress in two or three months."
