COVID-19 an infectious disease caused by a coronavirus that spreads through the droplet transmission method. The disease can spread from person-to-person mainly via respiratory droplets resembling the spread of influenza. The droplet transmission virus is transmitted when a person with infections coughs, sneezes, or talks to another person. But only, if it makes direct contact with mucous membranes. Infection can also occur if a person touches an infected surface and then touches his or her eyes, nose, mouth. The droplets do not travel more than six feet and do not linger in the air.  

The Severe acute respiratory syndrome coronavirus (SARS-COV) and Middle East respiratory syndrome coronavirus (MERS-COV) are the two highly transmissible and pathogenic viruses. Both viruses have emerged in humans at the beginning of the 21st century that cause severe respiratory tract infections. Likely this COVID-19 has emerged on Dec.2019 at Wuhan, China. SARS-CoV-2 is the scientific name of COVID-19.

A complete DNA testing and phylogenetic analysis(the study of the relationship of the species) by the experts resulted that the coronavirus that causes COVID-19 is a beta coronavirus. Bats are the primary source of the coronavirus.  Most people infected with COVID-19 will experience mild to moderate respiratory illness and recover without requiring Special treatment. Older people and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.


People may be sick with the virus for 1 to 14 days before developing symptoms. Common symptoms of COVID-19 include fever, tiredness and dry cough. Other symptoms include shortness of breath, aches, pains, sore throat and very few people who will report diarrhea,  nausea or a running nose. People with mild symptoms who are otherwise healthy should isolate themselves for the prevention of the spread of the disease. People with fever, cough or difficulty should call their doctors and seek medical attention for their and their society’s welfare.


Wash your hands regularly with soap and water or clean them with alcohol-based hand rub. Maintain at least 1-meter distance between you and people coughing or sneezing. Avoid touching your face and cover your mouth and nose when coughing or sneezing. Stay home if you feel unwell. Practice social distancing by avoiding unnecessary travel and staying away from large groups of people. Because the more you socialize, the higher will be your chances to get the virus. So, stay away from people for some time, it will be for your own good.
