Coronaviruses are a large group of viruses that are known to cause diseases. Patients show different symptoms from the common cold to severe lung infections, such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The new coronavirus (nCoV) is a new type of coronavirus that has not been found in humans, such as the new type of coronavirus 2019-nCov in Wuhan, China.
What are the characteristics of the new coronavirus and new pneumonia?
Can humans be infected with new coronaviruses of animal origin?
According to previous detailed investigations, SARS-CoV spread from civet cats in China to humans in 2002, while MERS-CoV spread from dromedaries to Saudi Arabians in 2012. In addition, there are several known coronaviruses that are circulating in animals, but have not yet infected humans. As surveillance improves worldwide, more coronaviruses may be discovered.
What are the symptoms of people infected with the coronavirus?
Symptoms depend on the type of virus infected, but common symptoms include respiratory symptoms, fever, cough, shortness of breath, and difficulty breathing. In more severe cases, the infection can lead to pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Can the coronavirus spread from person to person?
Yes, certain coronaviruses can spread from person to person, usually after close contact with an infected patient, such as in a home workplace or medical center. The 2019-nCoV in Wuhan, China was confirmed to have limited human-to-human transmission.
Is there a vaccine for the new coronavirus?
It takes time for new diseases to develop vaccines, and it may take years to develop new vaccines.
Is there a treatment for the new coronavirus?
There is no specific treatment for diseases caused by the new coronavirus. However, many symptoms can be treated, so it can be treated according to the patient’s clinical condition. In addition, supportive treatment for infected people can be very effective.
Will medical staff be threatened by the new coronavirus?
Yes, because health care workers have a higher frequency of contact with patients than the general public and are more susceptible to the threat of new coronavirus infection. Therefore, WHO recommends that health care workers always take appropriate infection prevention and control measures.
What can I do to protect myself?
Standard recommendations for reducing exposure and transmission of multiple diseases include maintaining basic hand and respiratory hygiene, safe eating habits, and avoiding close contact with people showing symptoms of respiratory diseases (such as coughing and sneezing) when possible .
What are the characteristics of the current pneumonia caused by the new coronavirus?
At the end of 2019, a new type of coronavirus-infected pneumonia epidemic occurred in Wuhan; recently, many provinces and cities in China have reported imported epidemics; on January 20, the Japanese city also notified a suspected case from Wuhan. Based on the analysis of domestic experts, this epidemic has two characteristics: one is that almost all the cases that have appeared are related to Wuhan and have been to or from Wuhan; the other is that signs of human-to-human transmission have been confirmed, including family members and family members. Infection of medical staff.
How to recognize this new infectious disease?
This new type of coronavirus is different from SARS and Middle East Respiratory Syndrome. Although it has homology, it is a virus of completely different nature. The infection of the new coronavirus has just begun, less than a month, and it is still climbing. We are still understanding many of the rules, so compared with SARS at that time, it is not as infectious and virulent. . In terms of the severity and spread of the disease, there are still differences between the two, so you don’t need to be so nervous.
Now that there are suspected imported cases in this city, are there any specific countermeasures?
Major infectious disease epidemics have always been our focus of prevention and control. We have experienced SARS, MERS, influenza A and other major infectious disease epidemics, established a relatively complete and well-functioning public health system, and responded to the previous events in a strong and orderly manner. Epidemics of infectious diseases have provided solid medical and health protection for large-scale events.
In the face of this epidemic, the municipal party committee and government have attached great importance to it, deployed early, and have been closely following the epidemic situation, conducting risk assessments in real time, constantly adjusting work strategies, and setting up a number of dedicated work teams to respond in an all-round way. The disease control agency purchases testing reagents immediately, strengthens personnel training, and improves emergency response capabilities; medical institutions at all levels have strengthened the screening, diagnosis and treatment of new coronavirus pneumonia in pre-inspection and triage and fever clinics, the discovery of this case It also reflects the sensitivity and effectiveness of our system. We are confident and capable of winning the battle against the epidemic and protecting the health of the people.
The early detection of the case was in the seafood market. We are a coastal city. Are seafood at risk?
The early cases in Wuhan were indeed concentrated in the South China Seafood Market, but this so-called seafood market is a large number of wild animals, which is a comprehensive market. From the perspective of the occurrence of major epidemics, the main risk is still in wild animals and has nothing to do with seafood. . It also reminds everyone that we must develop a healthy lifestyle and avoid contact with and eating wild animals, especially animals that die or are at great risk. With this kind of scientific understanding, we will prevent and control scientifically and deal with it scientifically, so don’t panic.
Judging from the current situation, who are susceptible to this new coronavirus?
The elderly have more infections, which is an important feature. Viruses are also changing, adapting to the environment and humans in the process of change. Therefore, the elderly should pay more attention to prevention.
