COVID-19 Overview and Prevention Guide

Coronaviruses can cause illness in animals and humans. COVID-19 is a new disease caused by a coronavirus called SARS-CoV-2. It emerged in China in late 2019 and has since spread globally to become a pandemic. COVID-19 causes respiratory symptoms like fever, cough and shortness of breath, and can be severe in some cases, especially in older people or those with underlying health conditions. The virus spreads mainly person to person via respiratory droplets from coughing, sneezing or talking. People can also catch it by touching contaminated surfaces. There is no vaccine currently but people can reduce risk of infection through hand washing, social distancing and other hygiene measures.

Overview

Coronaviruses possess a distinctive morphology, the name being derived from the


outer fringe, or “corona” of embedded envelope protein. Members of the
family Coronaviridae cause a broad spectrum of animal and human diseases. Prior
to 2003 members of this family were believed to cause only mild respiratory illness
in humans, other coronaviruses then known being largely of importance only to
the livestock industry. But the emergence of severe acute respiratory virus (SARS-
CoV) that year stimulated major research into these viruses, to the effect that
many new coronaviruses have since been discovered, some with zoonotic potential
of causing serious outbreaks of disease in humans. The more recent emergence of
MERS-CoV is exemplary.

 SARS COV : China 2003 (From cat)

 MERS COV : Saudi Arabia 2012 (From camel)

 2019-n-cov : China 2019

WHAT IS CORONAVIRUS?
Coronaviruses are a large family of viruses which may cause illness in animals or
humans.  In humans, several coronaviruses are known to cause respiratory
infections ranging from the common cold to more severe diseases such as Middle
East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome
(SARS). The most recently discovered coronavirus causes coronavirus disease
COVID-19.

Definition by WHO.

WHAT IS COVID-19 ?

PAGE 1
COVID-19 is the infectious disease caused by the most recently discovered
coronavirus. This new virus and disease were unknown before the outbreak began
in Wuhan, China, in December 2019. COVID-19 is now a pandemic affecting many
countries globally.

SIGN AND SYMPTOMS

 Fever
 Dry Cough
 Tiredness
 Difficulty in breathing
 Aches and pains
 Nasal Congestion
 Sore throat
 Diarrhea

PEOPLE AT HIGHER RISK


Older people and those with underlying medical problems like:

 High blood pressure


 Heart problems
 Lungs problems
 Diabetic patient
 Cancer patient

HOW DOES COVID-19 SPREAD?

People can catch COVID-19 from others who have the virus. The disease spreads
primarily from person to person through small droplets from the nose or mouth,
which are expelled when a person with COVID-19 coughs, sneezes, or speaks.
These droplets are relatively heavy, do not travel far and quickly sink to the

ground. People can catch COVID-19 if they breathe in these droplets from a person
infected with the virus. This is why it is important to stay at least 1 meter (3 feet)
away from others. These droplets can land on objects and surfaces around the
person such as tables, doorknobs and handrails. People can become infected by
touching these objects or surfaces, then touching their eyes, nose or mouth. This is
why it is important to wash your hands regularly with soap and water or clean with
alcohol-based hand rub.

WHO is assessing ongoing research on the ways that COVID-19 is spread and will
continue to share updated findings.

PREVENTIVE MEASURES:

 Practice hand and respiratory hygiene.


 Maintain at least 1 meter (3 feet) distance between yourself and others.
 Use mask and gloves before leaving home in case of emergency.
 Wash your hand regularly with soap and clean water for at least 20
seconds.
 Avoid touching eyes, nose and mouth.
 Avoid crowd.
 Stay quarantined for at least 14 days if you feel you are exposed to infected
person.
 If any sign and symptoms are seen, seek medical care as soon as possible.
 Stay informed and follow advice given by your health care professional.

Thank You!!!
