Currently, before the disease caused by corona virus increased rapidly and complicatedly. We need to have a clear understanding of disease prevention and timely prevention of the increasing number of pandemics.

We must know the source as well as the signs of the disease and how to prevent it. The corona virus (nCoV) is a new respiratory virus that causes acute respiratory infections in humans and has been shown to be spread from person to person. Corona viruses, like MERS and SAR, are all derived from a host from a bat. The corona virus is a large family of viruses, common in many different animals including camels, cats and bats.

The virus initially originated from animal sources but has the ability to spread from person to person. It is important to note that the spread from person to person can occur continuously. In humans, the virus spreads from person to person through contact with infected body fluids. Depending on the degree of spread of the virus, coughing, sneezing or shaking hands can expose people to exposure. The virus can also be spread by touching someone on an object, then on their mouth, nose, and eyes. Caregivers may also be exposed to the virus when handling the patient's waste. So, "There are two ways of transmission of this type of nCoV (corona): The first is direct contact with droplets. The second is touching, touching the substances in the throat area of ​​the patient. , then put on face, nose and mouth".

So what are the symptoms when infected with this virus ?. Pay attention to fever, cough and difficulty breathing. These symptoms can appear 2 to 14 days after exposure. By the onset, nCoV can develop to severe pneumonia, progressive respiratory failure and death, especially in people with chronic disease, immunodeficiency.

Therefore to prevent disease, we should pay attention to the following: Limit direct contact with people with acute respiratory infections; When necessary contact with sick people must wear a proper medical mask and keep a distance when exposed.
Keep your body warm, keep personal hygiene, wash your hands often with soap, gargle with antiseptic water to prevent pneumonia.
Cover your mouth and nose when coughing or sneezing, preferably with a cloth or a handkerchief to reduce the spread of respiratory secretions.

I hope we have the knowledge of this disease to help not only ourselves but also the whole community join hands to fight the pandemic caused by corona virus to humanity.
