Virus coronavirus

What is coronavirus?

The new coronavirus 2019 (2019-nCoV) was discovered in Wuhan virus pneumonia cases in 2019, and was named by the World Health Organization on January 12, 2020. Now WHO rename it as COVID-19. Coronaviruses are a large family of viruses that are known to cause colds and more serious diseases such as the Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The new coronavirus is a new coronavirus strain that has never been found in humans before.

Since December 2019, Wuhan City, Hubei Province has continued to carry out surveillance of influenza and related diseases, and found multiple cases of viral pneumonia, all of which were diagnosed with viral pneumonia/pulmonary infection.

Common signs of a person infected with a coronavirus include respiratory symptoms, fever, cough, shortness of breath, and dyspnea. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death. There is currently no specific treatment for diseases caused by the new coronavirus. However, many symptoms of coronavirus can be controled, so they need to be treated according to the clinical situation of the patient. In addition, assistive care for infected people can be very effective.

Symptoms of Coronavirus

  1. Fever, mainly manifested as a fever similar to a common cold, etc.
  2. Weakness, feeling weak, unwell.
  3. Dry cough, above symptoms are relatively mild cases
  4. Feeling breathing becomes increasingly difficult, which is the biggest difference from a common influenza.

People infected with the virus will experience symptoms to varying degrees, some with fever or a mild cough, some with pneumonia, and some with more severe or even death. The lethality of the virus is about 2% to 4%, but this is a very early percentage and may change as more information becomes available. At the same time, this does not mean that it is not serious, it just means that not everyone infected with the virus will face the worst consequences.

Coronavirus News

Coronvirus disease outbreak in China:

In December 2019, some hospitals in Wuhan appeared patients with unexplained pneumonia. Wuhan City continued to carry out surveillance of influenza and related diseases and found 27 cases of viral pneumonia, all of whom were diagnosed with viral pneumonia / pulmonary infection.

As of December 31, 2019, of the 27 cases, 7 were critically ill, and the remaining cases were in controllable condition, and 2 of them were improved and are expected to be leave soon. In the morning of December 31, 2019, an expert group of the National Health Commission arrived in Wuhan, and related virus typing testing, isolation treatment, and terminal disinfection were in progress.

On January 3, 2020, according to the website of the Wuhan Municipal Health and Health Commission, since December 2019, our commission has carried out surveillance of respiratory diseases and related diseases and found cases of viral pneumonia of unknown origin. The clinical manifestations of the cases are mainly fever, and a few patients Difficulty breathing, chest X-ray showed invasive lesions of both lungs. Till 8:00 on January 3, 2020, a total of 44 patients with unexplained diagnosis of viral pneumonia were found, of which 11 were critically ill, and the vital signs of the remaining patients were generally stable.

On the evening of January 5, 2020, the Wuhan Municipal Health Commission informed that Wuhan had reported a total of 59 patients with unexplained diagnosis of viral pneumonia, including 7 critically ill patients.

On February 10, 2020, Hubei Province held a press conference on the prevention and control of the new coronavirus pneumonia epidemic. Zhang Dingyu, deputy secretary of the party committee and director of Wuhan Jinyintan Hospital, introduced that new coronavirus pneumonia is actually a self-limited disease. "The cure rate in our hospital is still very high. At present, the number of patients with new coronavirus pneumonia treated in our hospital has exceeded 1500. The majority of patients, including severe and critically ill patients, have undergone various oxygen therapy, symptomatic treatment and After the immunomodulatory treatment, they can be discharged smoothly, and the citizens do not have to be overly panicked.

Who coronavirus

People of all ages may be infected easy, mainly adults, and elderly and frail people seem to be more likely to be infected. There is no evidence that pets such as cats and dogs can be infected. Children and pregnant women are vulnerable to new coronavirus infections.

Coronavirus Spread Way

The main routes of transmission of new coronaviruses are respiratory droplets and contact transmission. Aerosol and fecal-oral routes of transmission need to be further clarified. Epidemiological investigations have shown that cases can be traced to close contact with confirmed cases.

Direct spread

Refers to the infection caused by the patient's sneezing, coughing, talking droplets, and exhaled gas directly inhaled;

Aerosol transmission

It means that the droplets are mixed in the air to form an aerosol, which causes infection after inhalation;

Contact spread

It means that the droplets are deposited on the surface of the article, contact the contaminated hands, and then contact the mucous membranes such as the oral cavity, nasal cavity, and eyes, causing infection.

How to prevent the COVID 19?

How to prevent infection with coronavirus? The Beijing Centers for Disease Control and Prevention recommends strengthening personal protection, avoiding contact with wild poultry and animals, and preventing sickness from going to work and gatherings. When you return from a trip to Wuhan and other places, if you have symptoms of respiratory infections such as fever and cough, you should choose a hospital based on the condition and send a mask to the doctor, and inform the doctor of a similar patient or animal contact history, travel history, etc. The specific suggestions are as follows:

1. Strengthen personal protection

1.1. Avoid crowded public places. Avoid contact with patients with fever and respiratory tract infections. Wear masks if needed.

1.2. Wash your hands frequently. Especially when hands are contaminated with respiratory secretions, after touching public facilities, after taking care of patients with fever, respiratory infections, or vomiting and diarrhea, after visiting hospitals, handling contaminated items, and after contacting animals, animal feed or animal feces.

1.3. Don't spit. Cover your mouth and nose with a tissue or elbow when sneezing or coughing.

1.4. Strengthen exercise, regular work and rest, and maintain indoor air circulation.

2. Avoid contact with wild poultry

2.1. Avoid contact with poultry, wild animals and their excreta and secretions, and avoid buying live birds and wild animals.

2.2. Avoid going to animal farms and slaughterhouses, live poultry animal trading markets or stalls, wildlife habitats or other places. You must take precautions when you travel, especially for occupationally exposed people.

2.3. Avoid eating wild animals. Do not eat animals and their products that are already sick; buy chilled poultry from regular sources, fully cook poultry, eggs, and milk, and handle fresh and cooked products separately and clean them in time to avoid cross-contamination.

3. Put an end to work and party

If you have symptoms of respiratory tract infections such as fever and cough, take a rest at home, reduce outing and travel, and use more ventilation in the room when the weather is good. Please wear a mask when contacting others. Avoid getting sick at work, class and parties.

4. Seek medical treatment in a timely manner

If you return from a trip to Wuhan and other places, if you have symptoms of respiratory infection such as fever, cough, etc., you should choose a hospital based on the condition to send a fever clinic for treatment, wear a mask, and inform the doctor of similar patient or animal contact history, travel history, etc.

See doctor in time while you feel unwell.

Viral pneumonia is more common in winter and spring, and can be spread or outbreak. The clinical manifestations are fever, soreness, dyspnea in a small part, and lung infiltration. Viral pneumonia is related to the virulence of the virus, the route of infection, and the age and immune status of the host. Viruses that cause viral pneumonia are common with influenza viruses, others are parainfluenza viruses, cytomegaloviruses, adenoviruses, rhinoviruses, and coronaviruses. Confirmation depends on pathogenic tests, including virus isolation, serological tests, and viral antigen and nucleic acid tests. The disease is preventable and controllable, and indoor air circulation is prevented to prevent public places and closed places where there is no air circulation. People can wear masks when going out. Symptomatic treatment is the main clinical practice, and bed rest is required. If you have the above symptoms, especially the persistent fever, you should go to the medical institution in time.

Coronavirus Detection Methods

  1. Nucleic Acid Test, high accuracy diagnose, recommend to use.
  2. Lateral Flow COVID19 Test Kit, rapid screening test kit, short time to results.
COVID TEST KIT assay various specimen

Guidelines for Prevention COVID-19

Guidelines for the protection of people with different risks of new coronavirus infection

In order to guide the protection of people at different risks of the noval  coronavirus infection, this guideline is specially formulated. This guide is applicable to ordinary householders, travellers, home quarantines, and people in specific industries.

I. Ordinary household personnel
