2. CORONA VIRUS
• Coronaviruses (CoV) are a large
family of viruses that cause illness
ranging from the common cold to
more severe diseases such as
Middle East Respiratory Syndrome
(MERS-CoV) and Severe Acute
Respiratory Syndrome (SARS-CoV).
• Coronavirus disease (COVID-19) is
a new strain that was discovered
in 2019 and has not been
previously identified in humans.

cells and provides a blue print for vaccine design

4. HOW TO PROTECT YOUR SELF
• Wash your hands frequently
• Maintain social distancing
• Avoid touching eyes, nose and mouth
• Practice respiratory hygiene
• If you have fever, cough and difficulty breathing, seek medical care
early
• Stay informed and follow advice given by your healthcare provider

5. Myth Busters
• COVID-19 virus can be transmitted in areas with hot and humid
climates
• Cold weather and snow CANNOT kill the new coronavirus.
• Taking a hot bath does not prevent the new coronavirus disease
• The new coronavirus CANNOT be transmitted through mosquito
bites.
• Are hand dryers effective in killing the new coronavirus?

6. When and how to use masks
• If you are healthy, you only need to wear a mask if you are taking care of a person with suspected
2019-nCoV infection.
• Wear a mask if you are coughing or sneezing.
• Masks are effective only when used in combination with frequent hand-cleaning with alcohol-
based hand rub or soap and water.
• If you wear a mask, then you must know how to use it and dispose of it properly.
• Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.
• Cover mouth and nose with mask and make sure there are no gaps between your face and the
mask.
• Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub
or soap and water.
• Replace the mask with a new one as soon as it is damp and do not re-use single-use masks.
• To remove the mask: remove it from behind (do not touch the front of mask); discard
immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.

9. How to clean hands?
• Clean your hands by rubbing them
one another with a lotion
containing alcohol, which is
deemed to be the favorable way
for cleaning hands on a regular
basis in case they are not overtly
unclean.
• It is more effective, and more
endurable by the hands than water
and soap.
• Wash your hands with water and
soap whenever they are overtly
contaminated with blood or other
body secretions, and after toilet.
