  • Severe Acute Respiratory Syndrome (SARS)  (incubation period usually 2-7 days but it may be up to 10 days) which first occurred in the Guangdong province in southern china.
  • Middle East Respiratory Syndrome (MERS)  (incubation period usually 2-14 days. 5-6 days an average)
  • Coronavirus Disease 2019 (COVID19) (the average incubation period usually found 5-6 days but symptoms appears within 11-12 days of exposure) and some causes common cold and flu.

Corona means “crown” and outside of virus composed from protein that look like a crown.  The virus is primary disperse through droplets of saliva produced by coughing, sneezing, and talking, it may also infected by touching and contaminated surface.

The droplets of saliva disperse about 6 feet away.  By touch, breathe or swallow them the virus get into body and infections causes after incubation in the host person body. Some people shows the symptoms and some people who have the virus but don’t have symptoms, still they can spread the virus.

Virus can also spread from touching a contaminated surface, then touching mouth, nose and eyes. Most of the virus can live on the objects for several hours on various types of surface like

Copper:  about 4 hours, cardboard: about 24 hours, plastic: 2 to 3 days, stainless still surface: 2-3 days. Therefore it very important to disinfect surface to get rid of the virus.

  • headache
  • Muscle ache and body pain.
  • Repeated shaking with chills
  • Loss of smell and taste
  • Other respiratory symptoms
  • nausea

COVID-19 is more likely to cause common cold and flu and shortness of breath and other respiratory symptoms. About 80% of people recover from the symptoms without any special medical treatment. However, some older adults and people become seriously ill after being exposed to COVID -19. There is no evidence that children are at greater risk for getting the virus.


People who have some medical illness like cardiovascular disease, sickle cell disease, Chronic respiratory disease, Type 2 Diabetics, cancer, chronic kidney diseases,  weakened immune systems, Obesity, Pregnancy, moderate and severe asthma, high blood pressure, liver disease, Thalassemia, type – 1 diabetes, Smoking, Cystic fibrosis, Pulmonary fibrosis, Dementia are at the highest risk of developing more severe symptoms.


  • Hand wash – wash your hand with the soap and water or clean them with a 60% alcohol-based sanitizer.This will destroys viruses on your hand.
  • Follows the social distancing: stay home stay safe. You should stay home as much as possible, due to some emergency you have to go outside, keep a distance of at least 6 feet away from each others.

  6. Rapid diagnostic test based on the antigen (RDT). Sample is taken from nose, throat and lungs. This test based on the detection of viral protein (Antigens) . This is speedy and accurate diagnosis method and its usage is CDC-approved.
  7. Rapid diagnostic test based on antibody (RDT). This test base on the detection of antibodies in the blood of COVID -19 infected people. Age, medication, infections, severity of disease are the factors affects the strength of antibody response.
