On June 12, Guangzhou Municipal Government held a press conference to inform the latest situation of epidemic prevention and control and other work. At the meeting, the Guangzhou Center for Disease Control and Prevention announced a major discovery that deserves everyone's vigilance.
Nearly 60% of the cases are treated as colds
Yang Zhicong, director of Guangzhou Municipal Center for Disease Control and Prevention, specifically reminded at the press conference that the municipal disease control has made a major discovery of this epidemic in a large number of epidemiological investigations reports:
Nearly 60% of the confirmed cases completely ignore the occurrence of the epidemic around them when they have symptoms such as fever, dry cough, dizziness, fatigue, sore throat, , loss of smell (taste), diarrhea, etc.
thought they just had common cold , so they took their own cold medicine. The nucleic acid test was not conducted in time at the nearest fever clinic, which delayed the optimal treatment time and early treatment time.
There are many elderly patients, and 80% of patients will have fever
According to the traceability of 39 epidemiological investigation teams in Guangzhou, it was found that the confirmed patients and asymptomatic infected persons of have a highly homologous virus genome sequence and are the same transmission chain. So, what are the overall characteristics of this round of epidemic in Guangzhou?
Experts from the medical treatment group of the Guangdong working group of the Comprehensive Group of the State Council’s Joint Prevention and Control Mechanism said that there are more elderly patients in this epidemic. Among them, more than 40% of patients over 60 years old are currently 9 patients over 80 years old in the ward, with the highest age of 95 years old.
"The viral load in the patient is relatively high, and the nucleic acid is relatively slow to turn negative, but the condition progresses relatively quickly. Some patients turn into severe illness after 3-4 days of onset." said Zhang Zhongde, .
patients have obvious symptoms. In other places, the main symptoms are that there are not many patients with fever, but there are not so high. About 80% of the patients here have fever, and it is very high. The load of the virus is very high, and the load of the virus is slow.
The new strain has a high pathogenic rate, and it only takes 3-7 days to turn into severe illness
During the epidemic in Guangzhou, what is the difference between the proportion of severe patients and the previous epidemics in other cities?
Guan Xiangdong, an expert from the medical treatment group of the Guangdong Working Group of the Comprehensive Group of the State Council’s Joint Prevention and Control Mechanism, said that compared with patients who have experienced local clustered epidemics since the Wuhan epidemic and more than 20 subsequent local clustered epidemics, the proportion of patients entering severe and critical this time is relatively high, with this batch of patients being about 10% to 12%.
In the past, some were 2% to 3%, some were 5% to 8%, and some were 8% to 10%. This batch is relatively high, and it is possible that this batch of epidemic strains has a relatively strong pathogenicity rate.
Guanxiangdong believes that the epidemic in Guangzhou has four characteristics in clinical manifestations.
First, the virus has a short incubation period, and most of them are affected within one week after infection.
Second, the proportion of patients who turn to severe and critical after onset of the disease is higher than before, reaching 10%-12%, and more than 12% of patients need oxygen therapy.
and the time to be converted to heavy or critical is advanced. In the past, it took 6-10 days, but most of this time only have 3-7 days.
Third, the patient's CT value is very low. The lower the CT value, the higher the viral load in the body.
Fourth, because of the high viral load, the time it takes for patients to turn negative for nucleic acid is also extended. In the past, cases of continuous negative nucleic acids could be found in about 10 days.
This time, the Guangzhou epidemic began to appear from late May to June 10, and the first batch of 4 infected people were discharged from the hospital.
A characteristic of the family cluster epidemic in Guangzhou is that the elderly and children are infected more often. During this epidemic, most of the severe patients are 70-90-year-olds, which also makes the treatment more difficult.
Expert's words:
At present, the epidemic abroad is still at a high level, and local confirmed cases of new coronavirus pneumonia have appeared in many places in China. These once again remind us that epidemic prevention and control cannot be relaxed!
Especially, ordinary people cannot distinguish between new coronary pneumonia and common cold, and do not make a rough diagnosis at home. Once you find that the condition suspected of a common cold has worsened, especially if you have fever, don’t hesitate and seek medical treatment immediately on the premise of taking good protection!
