On October 24, public health experts reminded that this round of epidemic in Zhengzhou is highly concealed and spreading, with a wide spread, a fast spread, and a relatively weak toxicity.
What is the current virus in Henan Province? How is it different from before? htmlOn October 25, a reporter from Dahe Daily Yu Video interviewed You Aiguo, an infectious disease prevention and control expert of the Provincial Center for Disease Control and Prevention, and gave a detailed interpretation of the current virus characteristics and preventive measures in our province.
This round of epidemic, virus has 6 characteristics
You Aiguo introduced that The strain of this round of epidemic in Henan Province is the branch of Omickron strain BA.5.2. The virus mainly has the following 6 characteristics:
☞ spreads fast, has strong occultness, and is highly contagious. The BA.5.2 strain is one of the most popular strains with the strongest transmission power in my country, and its transmission ability has increased significantly compared with the previous strains.
☞ The latency and generation interval are short. The average incubation period of this epidemic in Zhengzhou is 2.8 days, and the average generation interval is 2.4 days. The shortening of the incubation period has led to the shortening of the case generation interval, bringing greater challenges and difficulties to epidemic prevention and control.
☞ virus resistance is enhanced. The increase in vitro survival time has further increased the ability to spread the epidemic and increased the possibility of "transmitting things to people".
☞ immune escape ability is enhanced. Due to the viral immune escape and the natural decline of immunity after vaccination, the vaccine's ability to protect individuals from infection has been severely reduced.
At present, most people in Henan Province have completed strengthening immunity at the end of last year and early this year. As time goes by, the protection rate will further decline, which has also caused more cases of infection in this round of epidemic.
☞ Most cases have lower nucleic acid Ct value, large viral load, and stronger infectiousness when the test is positive. Many cases have tested nucleic acid for for multiple times. Once positive is found, the Ct value of is low, and the virus has caused infection to the surrounding population.
☞ has mild clinical symptoms and strong occultness, which brings difficulties to early detection of the epidemic. Most of the infected people are asymptomatic who have no clinical manifestations, but are contagious.
Seven aspects should be paid attention to in daily protection
What preventive measures should the public take in response to the characteristics of this virus? You Aiguo said that we should pay attention to the following seven issues.
☞ Maintain good personal and environmental hygiene, wash hands frequently, wear masks, cover your mouth and nose with tissues when sneezing or coughing, and keep your home and workplace well ventilated.
☞ Ensure adequate rest and sleep, avoid excessive fatigue, balanced nutrition, and moderate exercise.
☞ minimize unnecessary outings, do not gather, and maintain social distance.
☞ html If you have been to medium- and high-risk areas within 37 days or have a history of contact with confirmed patients or asymptomatic infections, you should actively report to the community and implement centralized isolation measures.
☞ cooperates with the local and community to implement regional nucleic acid testing, conduct nucleic acid testing in accordance with the frequency requirements of nucleic acid testing, and strive to achieve early detection.
☞ Get vaccinated early. If has not completed the full vaccination process or the enhanced vaccination is strengthened, you should go to the nearby vaccination site as soon as possible to receive the new crown vaccine in order to build a solid immune barrier.
☞ When there are respiratory symptoms such as fever, sore throat, cough, etc., go to the nearby hospital for treatment in time.
Interpreting three hot issues in response to this round of epidemic
[1] How do people do it?
"Individuals should still tighten the string of epidemic prevention and control, don't be lucky, remember that the danger comes from carelessness." Henan Disease Control reminds that epidemic prevention and control cannot be relaxed at all, and everyone is the first person responsible for their own health. Take personal protection, protect yourself and others.
Proper wearing of masks is an important step in taking good protection. Nucleic acid testing is a key means to quickly discover hidden sources of infection, and it is also the legal responsibility and obligation of every citizen.
reminds everyone: stick to wearing masks scientifically, wash hands frequently, ventilate frequently, and do not gather . Maintain safe social distance and develop good hygiene habits. Everyone must become the number one responsible person for their own health.
【2】 Why did go to a medical observation point and not sent to the hospital?
A citizen called and his family was detected as an asymptomatic infection. Why did he go to a medical observation point and not sent to the hospital?
In this regard, public health experts introduced that because the virus is very low in pathogenicity, most infected people only need medical observation and do not require medication, so a medical observation point was established. What is the purpose of
medical observation point? can not only allow asymptomatic infected people and mild patients to receive professional care, but also relieve the pressure of large hospitals.
At the medical observation point, medical staff closely observe the symptoms and signs of the infected person. If there are any changes, medical staff can take timely examination and treatment measures.
Some people wonder: Why can't asymptomatic infected people and mild patients be isolated and observed at home?
Experts introduce: Family members may include elderly people, children, pregnant women, etc., and their resistance is relatively low. If they are isolated and observed at home, if the protection is improper, it is very likely that the new coronavirus will be transmitted to them. They are infected with the new coronavirus and develop into patients with new coronavirus or severe patients with new coronavirus pneumonia.
At the medical observation point, it can not only allow patients with mild symptoms to recover effectively but also protect their families to the greatest extent. This is the most critical.
【3】Can take antipyretic drugs by yourself? Since
is a mild symptom, can infected people take medicine by themselves when they have fever symptoms?
In this regard, experts remind that there are certain rules for this disease.
Among them, asymptomatic infected people may have no symptoms from beginning to end. For mild patients, they usually develop fever two or three days before the onset of the disease. The fever is usually moderate, without high fever, and continues at around 38 degrees. After two or three days, the body temperature gradually decreases, and the throat is sore and dry throat occurs. The pain is more obvious and will last for about two or three days. These two symptoms will disappear on their own after about a week.
So, specifically reminds everyone not to take medicine randomly, and do not take antibiotics randomly.
At the medical observation point, medical staff will monitor everyone every day and conduct nucleic acid tests on time. If necessary, I will give you some Chinese medicine decoctions and Chinese patent medicines to treat new coronavirus infection.
