What is COVID-19?

Coronavirus is a common virus that causes infections of the nose, sinuses, or upper pharynx. Most coronaviruses are not dangerous. In early 2020, after the outbreak in China in December 2019, the World Health Organization identified SARS: CoV-2 as a new type of coronavirus. The epidemic quickly spread to all parts of the world.

COVID-19 is a disease caused by SARS-CoV-2, which can cause so-called respiratory infections. It affects the upper respiratory tract (sinuses, nose, and throat) or the lower respiratory tract (trachea and lungs). It spreads in the same way as other coronaviruses, mainly through personal contact.

Infections range from mild to fatal. It is one of the seven types of coronaviruses, including coronaviruses that cause serious diseases, such as Middle East Respiratory Syndrome (MERS) and Sudden Acute Respiratory Syndrome (SARS). Other coronaviruses can cause the most common colds that affect us all year round, but they do not pose a serious threat to healthy people.


How long can coronaviruses last?

There is no way to know how long the pandemic will last. There are many factors, including public efforts to control this spread, researchers knowing more about the work of the virus, their search for treatments, and the success of vaccines.

The main symptoms are:

  • fever
  • cough
  • shortness of breath
  • difficulty breathing
  • fatigue and chills
  • sometimes trembling
  • body aches
  • headaches
  • sore throat
  • nasal congestion/runny nose
  • loss of smell or taste
  • nausea
  • diarrhea

The virus can cause pneumonia, shortness of breath, heart problems, liver problems, septic shock and death. Many complications of COVID-19 may be caused by a disease called cytokine release syndrome or cytokine storm. This happens when an infection causes your immune system to flood your blood with inflammatory proteins called cytokines.

They will kill tissues and damage your organs. If you or your loved one has severe symptoms, such as difficulty breathing or shortness of breath please see a doctor immediately. Is one side of your face tingling or sagging? Do you have a crooked smile? If you try to raise your hands, will one hand fall?

If you are infected, symptoms may last for 2 or 14 days. It depends on the individual. According to Chinese researchers, the most common symptom among COVID-19 patients is:

  • fever 99% of the time
  • fatigue 70%
  • cough 59%
  • loss of appetite 40%
  • body pain 35%
  • shortness of breath 31%
  • mucus/mucus 27%

Some people hospitalized for COVID-19 also have dangerous blood clots, including legs, lungs and arteries. What to do if you think there is. Even if you have mild symptoms such as headaches and runny nose, hold on until you feel better. This allows doctors to focus on critically ill patients and ensure the safety of medical staff and women. The street can call it self-isolation.

Try to stay in a separate room with other people in your house. However, please use a separate bathroom. If breathing is difficult, call a doctor. You should see a doctor as soon as possible. If you call ahead (instead of showing up), your doctor will direct you to a location that may not be your doctor’s office. If you do not have a regular doctor, please call your local health committee. They can tell you where to go for testing and treatment. Follow the doctor’s instructions and keep up to date with the latest news about COVID-19.
