Incase of coronavirus, prevention is always better than cure. Not a single covid-19 vaccine are not live yet, and we are still not sure how they will perform. So, it is critical to adopt preventive ways to protect yourself and others from the Novel COVID-19.

1) Wash Your Hands at Intervals

The foremost way is to wash your hands frequently. You must clean your hands with an alcohol-based sanitizer or with soap and water at intervals. It will kill viruses if present on your hands. We all must ensure that we follow basic guidelines to keep the coronavirus away as a not a single COVID-19 vaccine is not available yet for public use.

2) Continue Social Distancing

Next, you must practice social distancing. Social distancing must be of at least 1 meter (3 feet) between you and anyone who is coughing or sneezing.

Generally, hands touch many surfaces and get contaminated. The dirty hands can transmit the virus to your eyes, nose, or mouth. You will fall sick when the COVID-19 virus enters your body. Therefore, you must avoid touching your face, eyes, nose, or mouth with dirty hands.

4) Follow Respiratory Etiquette

All of us must follow good respiratory hygiene to protect others from viruses like flu, cold, and COVID-19. It means you must cover your mouth and nose with your flexed/bent elbow or tissue while coughing or sneezing. You must dispose of the used tissue immediately in a closed bin.

If you feel unwell, stay at your home, and wear a mask. You must avoid unnecessary travel or large public groups. This will help to keep away from this viral fever. If you feel COVID-19 symptoms, do not panic. Simply contact the nearest national or local health authorities without any delay. Avoid smoking as it declines lungs functioning. Also, do not travel unnecessarily.

6) Avoid Unventilated Indoors

We must also take care, that our houses or the rooms or the spaces where we are staying should be well-ventilated. Air purifiers, good ACs can regulate the flow of air and maintain hygiene. If we stay healthy and follow basic rules, then covid-19 can be defeated. And, we will not need a covid-19 vaccine too.

7) Get Medical Care Early if You Experience Fever, Cough, and Breathing Difficulty

In case you have a fever, cough, and shortness of breath, seek medical care by calling in advance. It is essential to abide by the directions of national or local health authorities. By attaining medical treatment early, this ailment can be cured.

It is important to disclose your contact with an infected person or past travel history (past 14 days) to any COVID-19 affected country/region to your medical care provider. It is significant to follow the guidelines of the Government to assist in fighting this disease. Mentioned here are few immunity boosters.
