The document provides information about COVID-19 (coronavirus) from its symptoms and treatment to how it spreads. It begins with an introduction to the global pandemic and defines coronavirus. It then discusses what coronavirus is, where it originated from, its symptoms, how it affects the body and is treated. The document also covers how coronavirus spreads, myths about it, where it can survive on surfaces, and current statistics.

3. INTRODUCTION
As you all know that our whole world is
suffering from a great pandemic caused by
disease called CORONA VIRUS. Due to this all
offices , school , markets , malls , factories,
Parliament , and social places are closed
Corona virus disease (COVID-19) is an
infectious disease caused by a newly
discovered Corona virus.

5. WHAT IS CORONA VIRUS(COVID-19)
Coronaviruses are a group of related viruses that cause diseases
in mammals and birds. In humans, coronaviruses cause respiratory tract
infections that can range from mild to lethal. Mild illnesses include some
cases of the common cold (which has other possible causes,
predominantly rhinoviruses), while more lethal varieties can
cause SARS, MERS, and COVID-19. Symptoms in other species vary: in
chickens, they cause an upper respiratory tract disease, while in cows and
pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to
prevent or treat human coronavirus infections.
Corona viruses constitute the subfamily Orthocoronavirinae, in the
family Coronaviridae, order Nidovirales, and realm Riboviria.[5][6] They
are enveloped viruses with a positive-sense single-
stranded RNA genome and a nucleocapsid of helical symmetry.
The genome size of corona viruses ranges from approximately 27 to
34 kilobases, the largest among known RNA viruses.

7. FROM WHERE IT COMES
On December 31, 2019, the World Health Organization's
(WHO) China office heard the first reports of a
previously-unknown virus behind a number of
pneumonia cases in Wuhan, a city in Eastern China with
a population of over 11 million.
The disease appears to have originated from a Wuhan
seafood market where wild animals, including marmots,
birds, rabbits, bats and snakes, are traded illegally.
Coronaviruses are known to jump from animals to
humans, so it’s thought that the first people infected
with the disease – a group primarily made up of
stallholders from the seafood market – contracted it
from contact with animals.

9. SYMPTOMS OF CORONAVIRUS
According to the WHO, the most common symptoms of
Covid-19 are fever, tiredness and a dry cough. Some
patients may also have a runny nose, sore throat, nasal
congestion and aches and pains or diarrhoea. Some people
report losing their sense of taste and/or smell. About 80%
of people who get Covid-19 experience a mild case – about
as serious as a regular cold – and recover without needing
any special treatment.
About one in six people, the WHO says, become seriously
ill. The elderly and people with underlying medical
problems such as high blood pressure, heart problems or
diabetes, or chronic respiratory conditions, are at a
greater risk of serious illness from Covid-19.

10. SYMPTOMS

12. TREATMENT OF CORONAVIRUS
There is no specific medicine to prevent or treat
coronavirus disease (COVID-19). People may need
supportive care to help them breathe.
Self-care
If you have mild symptoms, stay at home until you’ve
recovered. You can relieve your symptoms if you:
rest and sleep
keep warm
drink plenty of liquids
use a room humidifier or take a hot shower to help
ease a sore throat and cough

14. WHAT IT DOES IN OUR BODY
This is when the virus is establishing itself.
Viruses work by getting inside the cells your body is made of and
then hijacking them.
The coronavirus, officially called Sars-CoV-2, can invade your
body when you breathe it in (after someone coughs nearby) or
you touch a contaminated surface and then your face.
It first infects the cells lining your throat, airways and lungs and
turns them into "coronavirus factories" that spew out huge
numbers of new viruses that go on to infect yet more cells.
At this early stage, you will not be sick and some people may
never develop symptoms.
The incubation period, the time between infection and first
symptoms appearing, varies widely, but is five days on average.

15. The virus moves down your respiratory tract.
That’s the airway that includes your mouth,
nose, throat, and lungs. Your lower airways
have more ACE2 receptors than the rest of your
respiratory tract. So COVID-19 is more likely to
go deeper than viruses like the common cold.
Your lungs might become inflamed, making it
tough for you to breathe. This can lead
to pneumonia, an infection of the tiny air sacs
(called alveoli) inside your lungs where
your blood exchanges oxygen and carbon
dioxide.

16. WHAT HAPPENS TO OUR BODY

17. HOW IT SPREAD
The new coronavirus is a respiratory virus
which spreads primarily through droplets
generated when an infected person coughs
or sneezes, or through droplets of saliva or
discharge from the nose. To protect yourself,
clean your hands frequently with an alcohol-
based hand rub or wash them with soap and
water.

19. PREVENTION FROM CORONAVIRUS
There is currently no vaccine to prevent coronavirus
disease 2019 (COVID-19).
The best way to prevent illness is to avoid being
exposed to this virus.
The virus is thought to spread mainly from person-to-
person.
Between people who are in close contact with one
another (within about 6 feet).
Through respiratory droplets produced when an infected
person coughs, sneezes or talks.
These droplets can land in the mouths or noses of people
who are nearby or possibly be inhaled into the lungs.
Some recent studies have suggested that COVID-19 may
be spread by people who are not showing symptoms.

21. MYTHS ABOUT CORONAVIRUS
1. Spraying chlorine or alcohol on skin kills viruses in
the body
2. Only older adults and young people are at risk
6. Cats and dogs spread coronavirus
7. Face masks protect against coronavirus
11. Rinsing the nose with saline protects against
coronavirus
12. You can protect yourself by gargling bleach
20. The virus will die off when temperatures rise in the
spring
23. The virus originated in a laboratory in China
The outbreak began because people ate bat soup
It spread with air and water

23. How long it survive on a surface
The virus lives longest on plastic and steel,
surviving for up to 72 hours. But the amount of
viable virus decreases sharply over this time. It
does poorly on copper, surviving four hours.
On cardboard, it survives up to 24 hours, which
suggests packages that arrive in the mail
should have only low levels of the virus —
unless the delivery person has coughed or
sneezed on it or has handled it with
contaminated hands.
