The recent outbreak of novel coronavirus infection has attracted worldwide attention. The World Health Organization has issued guidelines for the clinical management of severe acute respiratory infections caused by suspected novel coronavirus infections. However, the guideline is mainly for clinicians to provide relevant diagnosis and treatment recommendations. In order to answer some of the confusion about novel coronavirus, we have compiled 8 questions and answers based on the official recommendations of WHO, hoping to help you to improve your understanding and do prevention at the same time.
8 points to prevent novel coronavirus infection：
What are coronaviruses and novel coronaviruses?
Coronaviruses are a large group of viruses that are known to cause illnesses that vary from the common cold to severe lung infections, such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).
Novel coronavirus (nCoV) is a novel coronavirus that has not been previously identified in humans, as in the case of the novel coronavirus 2019-nCov in Wuhan, China.
Can humans be infected with novel viruses of animal origin?
Based on previous detailed investigations, SARS-CoV was transmitted from civets to humans in China in 2002, and MERS-CoV was transmitted from dromedary camels to people in Saudi Arabia in 2012. Several other coronaviruses are known to be circulating in animals but have not yet infected humans. As technical conditions for worldwide surveillance improve, more coronaviruses may be identified.
What are the symptoms of coronavirus infection in humans?
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 coronaviruses be transmitted from person to person?
Yes, some coronaviruses can be transmitted from person to person, usually after close contact with an infected patient, for example in the home, workplace or medical center. This time, 2019-nCoV in Wuhan, China, was confirmed to have a possible limited human-to-human transmission.
Is there currently a vaccine for the novel coronavirus?
Emerging diseases require time to develop a vaccine for vaccination and the development of a new vaccine may take several years.
Is there a treatment for novel coronaviruses?
There is no specific treatment for the disease caused by the novel coronavirus. However, many of the symptoms are treatable, so treatment can be tailored to the clinical status of the patient. In addition, supportive treatment for infected individuals may be very effective.
Are health care workers more at risk?
Yes, because health care workers have more frequent contact with patients than the general public and are more at risk of novel coronavirus infection, 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, as well as safe eating habits, and avoiding close contact with people who exhibit symptoms of respiratory illness (such as coughing and sneezing) when possible.
