      OVERVIEW
      • Corona viruses are RNA viruses and belong to a family of viruses capable of causing illnesses such as the common cold, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).
      • A new corona (novel) virus that originated in China was identified in 2019 responsible for an outbreak of respiratory illness of varying severity
      • The virus responsible for the current outbreak is termed the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), and the condition caused by it is referred to as (COVID-19).
      • The current outbreak was declared a pandemic by the WHO in March 2020

      TRANSMISSION OF CORONA VIRUS
      • Corona viruses are zoonotic organisms, which means that they initially infect animals from whom humans get the infection. Therefore persons in close contact with animals are at increased risk
      • The current 2019 pandemic is not specifically linked to any animal
      • Once the corona virus infects humans, it can be spread from person to person via respiratory droplets/ aerosol. This refers to the spray of wet stuff that is released into the atmosphere when a person coughs or sneezes.
      • These droplets contain the virus and are inhaled into the respiratory tract (windpipe and lungs), where it develops and causes symptoms of the disease

      PERSONS AT HIGH RISK
      • Medical personnel treating sick patients
      • Those caring for persons with the illness
      • Living in close contact with someone who has the illness

      • Travel to and from endemic areas
      • Underlying lung disorders such as asthma and COPD
      • Heart disease

      DIAGNOSIS OF COVID-19
      To test for COVID-19, typically a long swab is used to take a sample from the nostril, which is then sent for testing. Other samples used less frequently include saliva and blood. Check your local government’s website to find where testing facilities are offered

      If symptoms are severe, admission to hospital may be necessary for supportive and symptomatic care. These include some experimental treatments as well such as
      In some cases, experimental treatments are being tried to see if they might be effective. Examples of such treatments used for include:
      • Respiratory support, such as mechanical ventilation
      • Steroids to reduce lung inflammation
      • Plasma transfusions
      • Antiviral or retroviral drugs

      Persons are advised to consult their doctors before taking any drug

      COVID-19 vs SEASONAL FLU
      It is still too early to say as data available on the current outbreak is insufficient, but initial evidence suggests that mortality rates due to COVID-19 may be higher than the seasonal flu virus

      According to available reports from CDC, approximately 1.2% deaths have occurred in COVID-19 cases compared to 0.06-0.1% deaths due to seasonal influenza infection

      • Maintain social distancing if you belong to high risk group (see above)
      • Wash hands frequently with soap and water for minimum 20 seconds, or hand sanitizer with at least 60% alcohol (proven to kill the virus)
      • Cover the mouth and nose with your elbow or tissue while sneezing or coughing. Throw away the used tissue.
