B occurs when a rapid infectious disease spreads in the population, and at the same time affects a large number of people over a period of time. If the outbreak affects large geographical areas (for example, several continents) that are classified as pandemics, this is the case of HIV. In the case of uncontrolled proliferation, the epidemic can lead to the collapse of the health system.
Since December 19, Wuhan City, Hubei Province, has detected several cases of unexplained viral pneumonia. The National Health and Safety Commission immediately dispatched a national working group and a team of experts to Wuhan to study and implement epidemic prevention and control measures in accordance with the principle of regional management. On January 8, 2020, it was initially confirmed that the new coronavirus was the causative agent of the outbreak.
▪ what is this new coronary virus?
▪ how are they different from coronary viruses and other previous epidemics?
▪ how much damage it will cause and how it can be prevented?
In response to these problems, I will explain to you about the new epidemic or coronavirus and ways to prevent it.
What is the coronary virus▪?
▪What is the new coronary virus?
The coronary virus is a large family of viruses, named after the virus morphology under an electron microscope like the crown.
To date, it has been shown that the coronary virus infects only vertebrates and can cause respiratory, gastrointestinal and nervous diseases in humans and animals, such as colds and more serious diseases such as Middle East Respiratory Syndrome (MIDDLE EAST Respiratory Syndrome) and Acute Respiratory Syndrome (SARS) and other epidemics.
The new coronary virus is a new strain of the coronavirus that has not been found in humans before.
In addition to the new coronary viruses discovered this time, there are six other coronaviruses known to infect humans.
Four of these are more common in the population, with reduced morbidity, usually causing mild respiratory symptoms similar to colds; the other two are the known coronary SARS virus and the Corse virus.
The new coronary virus that caused the outbreak of pneumonia in Wuhan this time is completely different from the past.
Like humans, although different viruses are close relatives, their mood and attitudes are very different. Although the new coronaviruses are close relatives of SARS, they have not shown the terrible characteristics of SARS at present. Preventive action.
▪Can the coronary virus be transmitted from person to person?
▪ what are the symptoms after infection?
Some coronary viruses can spread from person to person, and people are usually infected after close contact with infected people at home, at work or in medical facilities.
After a person is infected with the coronary virus, symptoms will vary from virus to virus. Common signs include respiratory symptoms, fever, cough, shortness of breath and difficulty breathing. In more severe cases, infection can lead to pneumonia, acute respiratory syndrome, kidney failure, and even death.
Patients with the new coronary virus showed fever, fatigue, dry cough, and progressive shortness of breath, while some patients had symptoms of mild onset and no fever; Nowadays, most patients are moderately moderate, with good diagnosis, and few patients suffer from a serious illness and die.
▪Can the new coronary virus be treated?
▪Is a vaccine available?
There are no vaccines available for new diseases. It may take several years to develop a new vaccine. There is currently no specific treatment for diseases caused by new coronary viruses.
However, many symptoms can be managed, so they must be treated according to the patient’s clinical condition. In addition, assistive care for infected people may be very effective.
▪What are close contacts?
▪ what do I do after informing the CDC that you are in close contact?
Close contact means the person who suffers from one of the following contact situations after the onset of the condition (observation and confirmed condition):
- (1) Persons who live, study, work or have close contact with the case;
- (2) Medical staff, family members or other persons with similar close contact with the situation when they did not take effective preventive measures during diagnosis, treatment and visit;
- (3) Other patients and their companions in the same case ward;
- (4) After investigation by on-site investigators, employees who are considered eligible for evaluation.
Keep an eye on home medical notes as required without panic.
Don’t go to work, don’t go out casually, do a good job for your physical condition, regularly follow up with community doctors, if you suffer from fever, cough and other abnormal clinical manifestations, report to the local agency for disease prevention and control in a timely manner, and go to the designated medical institution to investigate under its guidance diagnosis and treatment.
▪Are health workers at risk of new coronaviruses?
Yes, because health workers have more contact with patients than ordinary people, patients are at risk of developing new crown viruses. WHO recommends that health workers insist on infection prevention and control measures.
▪Five rumors about viral pneumonia in Wuhan
Recently, the Chinese Center for Disease Control and Prevention explained on its official website the five main rumors about viral pneumonia in Wuhan.
Rumor 1 “The mysterious disease that broke out in Wuhan, China, has been confirmed as a new type of SARS virus.””
Answer: Wrong. The pathogen has been identified as a new coronavirus.
Rumor 2 “The new Wuhan virus is similar to 73% of SARS? The genetic sequence of the new Koron virus is 80% similar to SARS?
Answer: Wrong. The genetic similarity of viruses cannot be equated with the similarity of the pathogenic ability of viruses. New coronary viruses belong to the same family of coronary viruses as SARS and MERS, but genetic development analysis shows that they belong to different subgroups and the sequences of viral genes vary relatively large.
Common 3 “There are already many cases in the hospital, which have been closely isolated. Very appalling, it is said that 80% of SARS.”
Answer: Wrong. The new coronavirus and SARS virus are not the same. The treatment of the isolation of infectious disease patients is required under the People’s Republic of China Act on The Prevention and Control of Infectious Diseases.
Rumor 4 “SARS did not disappear and was a parasite on the bat.””
Answer: Wrong. From 2002 to 2003, a SARS outbreak appeared in China. No SARS cases have been found in China for more than 10 years. At present, no human sars coronavirus has been detected in bats.
Rumor 5 “Wuhan pneumonia virus has a long history of SARS Corona virus.””
Answer: Wrong. Coronavirus, which is commonly transmitted online, has been translated from coronavirus (Coron virus), the pathogen that caused the epidemic of viral pneumonia in Wuhan is a new Coroneian virus, not a SARS virus. The current investigation shows that the ability of the virus to spread and nurse among people is weaker than the SARS virus.
▪How do you protect yourself?
Standard recommendations to reduce exposure and reduce the spread of a range of diseases include maintaining basic hand and respiratory hygiene, adhering to safe eating habits, and avoiding the nearest possible person with symptoms of respiratory diseases (such as coughing and sneezing) contact.
At present, in the season of high incidence of infectious diseases citizens must promote health awareness, exercise, regular work, rest and improve their immunity.
Be careful to keep the indoor air circulation, avoid indoor and uncirculated public places and places where people are concentrated, and wear masks if necessary. After returning home, wash your hands and nose in time. If you have fever and other symptoms of respiratory infection, especially if the fever persists, go to the hospital in time.
