What You Need to Know about COVID-19

In late December 2019, a series of pneumonia cases caused by the novel coronavirus emerged in Wuhan, Hubei Province, China. The first infections seem to be linked to a seafood market. According to statistics, by February 26th, 2020, there were nearly 78,000 confirmed cases and more than 2,000 suspected cases in mainland China. Besides, more than 30 countries or regions have reported confirmed cases. The WHO Director-General has declared the outbreak of novel coronavirus a Public Health Emergency of International Concern on January 30th. Disease caused by the novel coronavirus officially has a name: COVID-19.

Although COVID-19 is easily infected, the mortality rate is about 2%. So, there is no need to be too afraid. To win this war with COVID-19, we should first know more about it.

What is Coronavirus?

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).

Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.

What is Coronavirus Disease 2019 (COVID-19)?

COVID-19 is an illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is a new coronavirus that has not been previously identified. The virus can spread from person to person and the transmission usually occurs in homes, workplaces, densely populated areas or hospitals, etc.

What are the Symptoms of COVID-19?

The symptoms of COVID-19 usually start between 2 to 14 days after getting infected.

Classic symptoms including:

  • Fever, fatigue, and dry cough.
  • A small number of patients with nasal congestion, runny nose, pharyngeal pain, diarrhea, and other symptoms.
  • In severe cases, dyspnea or hypoxemia usually occurred one week after the onset of the disease.

Note that there is no vaccine or specific treatment for COVID-19 at present.

How do You Protect Yourself?

According to the experts, COVID-19 spreads very quickly in the world and even may faster than SARS. It is easily transmitted through direct contact with respiratory droplets of an infected person, and touching surfaces contaminated with the virus. But you can reduce the risk of getting or spreading an infection using the following methods.

1. Reduce Outdoor Activities

  • Avoid going to places where diseases are prevalent.
  • Avoid going to crowded public places. For example, shopping malls, bus stations, cinemas, museums, etc.
  • Try to stay at home during the holidays.

2. Keep Hygienic

  • Wear masks if you want to go out. Surgical Masks or N95 Masks are recommended.
  • Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.
  • Keep any objects you touch a lot cleaner.
  • Maintain at least one meter (3 feet) distance between yourself and anyone who is coughing or sneezing.
  • Avoid touching eyes, nose and mouth.
  • Do not touch, purchase or eat wild animals. Maintain exercise, and eat healthy food.
  • Open your windows regularly.

3. Seek Medical Advice in Time

  • Take your own temperature every day.
  • If you have any symptoms, please wear a mask and go to the hospital timely.

In sum, as long as we take preventive measures, the chances of catching COVID-19 would be very small. Don’t stress yourself out. Having a good mood is also key to health.
