4. WHAT IS COVID-19?
● Coronavirus disease (COVID-19) is a
disease caused by the SARS-CoV-2 virus.
● Most people infected with the COVID-19
virus will experience mild to moderate
respiratory illness and recover without
requiring special treatment.

5. WHAT IS COVID-19?
● Elderly and those with underlying medical
problems like cardiovascular disease,
diabetes, chronic respiratory disease, and
cancer are more likely to develop serious
illness.
● The best way to prevent and slow down
transmission is to be well informed about
the COVID-19 virus, the disease it causes and
how it spreads.

7. TRANSMISSION OF COVID -19
● The virus can spread from an infected person’s when they cough,
sneeze, speak.These liquid particles are different sizes, ranging from
larger ‘respiratory droplets’ to smaller ‘aerosols’.
● Other people can catch COVID-19 when the virus gets into their
mouth, nose or eyes, which is more likely to happen when people are
in direct or close contact (less than 1 metre apart) with an infected
person.
● A person could get COVID-19 indirectly by touching a contaminated
surface (such as tables, doorknobs and handrails) or object before
touching their own mouth, nose, or eyes.

15. SOCIAL DISTANCING
● Social distancing, also called “physical distancing,” means keeping a safe space between
yourself and other people who are not from your household.
● To practice social or physical distancing, stay at least 6 feet (about 2 arm’s length) from other
people who are not from your household in both indoor and outdoor spaces.
● Social distancing should be practiced in combination with other everyday preventive actions
to reduce the spread of COVID-19, including wearing masks, avoiding touching your face with
unwashed hands, and frequently washing your hands with soap and water for at least 20
seconds

16. HANDWASH
● Handwashing is one of the best ways to protect yourself and your family from getting
sick.
● Before, during, and after preparing
food
● Before and after eating food
● Before and after caring for someone
at home who is sick with vomiting or
diarrhea
● Before and after treating a cut or
wound
● After using the toilet
● After blowing your nose, coughing,
or sneezing
Key Times to Wash Hands :

17. Steps of washing hands :
Hum the “Happy Birthday”
song from beginning to end
twice.!!wash your hands for at
least 30 seconds!!
REFERENCE:thedailynewsonline

18. HANDRUB
Washing hands with soap and water is the best way to get
rid of germs in most situations. If soap and water are not
readily available, you can use an alcohol-based hand
sanitizer that contains at least 60% alcohol. You can tell if
the sanitizer contains at least 60% alcohol by looking at
the product label.
Sanitizers can quickly reduce the number of germs on
hands in many situations. However,
● Sanitizers do not get rid of all types of germs.
● Hand sanitizers may not be as effective when hands
are visibly dirty or greasy.
● Hand sanitizers might not remove harmful chemicals
from hands like pesticides and heavy metals.

20. MASK
Choosing the Right Coronavirus Mask Type!
Wearing a mask is important for helping slow the spread of the virus,
especially when you decide to go out. It's also important to know what
type of mask you should wear and when it's appropriate to wear them
TYPE OF MASK
Cloth Mask Surgical
Mask
Face Shield
N-95 Mask
Reference:
https://www.umms.org/coronavirus/what-to-
know/masks/mask-types

21. CLOTH MASK
● A cloth face mask fits against the face
using either ear loops or ties around the
head. Multiple layers of fabric create a
barrier between your nose and mouth and
the outside, helping contain any
respiratory droplets that you may breathe
out. The thicker the mask, the greater the
barrier.
● You can easily make your own cloth mask
at home with or without a sewing machine
using a wide variety of fabrics, though
tightly woven fabrics like cotton are
recommended. These kinds of fabric
masks can also be useful when wearing a
mask in the heat or while exercising in a

23. SURGICAL OR MEDICAL MASK
● Surgical masks are disposable covers that are
usually worn by medical professionals as personal
protective equipment (PPE) during surgeries or
other procedures. They often made of a
combination of paper and plastics, and are
commonly light blue in color.
● Surgical masks are designed to protect against
large respiratory droplets but don't protect
against smaller droplets. They are effective for
helping protect others around you if you are a
carrier of the virus. While these masks are ideal
for one-time usage.

25. FACE SHIELDS
1. Face shields are clear sheets of plastic that hang down
from a headband, covering the face from the top of the
head to below the chin. Before the pandemic, they were
usually worn by health care workers performing
procedures that were prone to body fluid splatter. For
example, dental hygienists often wear face shields.
2. Members of the general public who keep six feet of
distance from others and wear a face mask do not
need a face shield. Face shields may be worn to
provide an extra layer of protection when in sustained
close proximity with others. However, they do not
provide the same protection as a mask because they
do not provide a barrier to respiratory droplets, which
can come up under them.

26. COVER!
● Always cover your mouth
and nose with a tissue when
you cough or sneeze or use
the inside of your elbow
and do not spit.
● Throw used tissues in the
trash.
● Immediately wash your
hands with soap and water
for at least 20 seconds. If
soap and water are not
readily available, clean your
hands with a hand sanitizer
that contains at least 60%
alcohol.
DISINFECT! MONITOR!
● Clean AND disinfect
frequently touched
surfaces daily. This
includes tables,
doorknobs, light switches,
countertops, handles,
desks, phones, keyboards,
toilets, faucets, and sinks.
● If surfaces are dirty, clean
them. Use detergent or
soap and water prior to
disinfection.
● Then, use a household
disinfectant
● Be alert for
symptoms. Watch for
fever, cough,
shortness of breath,
or other symptoms of
COVID-19.
● Especially important
if you are running
essential errands,
going into the office
or workplace, and in
settings.
● Take your
temperature if
symptoms develop.

28. PREVENTIVE MEASURES AT HOME
● Avoid drinking and eating cold beverages this may trigger the symptoms of flu
and throat infection which can give false judgement of covid related symptoms.
● Let only one family member go outside for performing all the essential chores
(preferably young adult )
● Avoid Senior Citizen and children going outside .
● Staying at home for longer duration can cause anxiety and in some cases
depression , indulge in small hobbies or group activities to keep the mind and
body activated
● Mopping of the floor can be done by disinfectant ,and vegetables can disinfect
by washing them in lukewarm water and soak them in saline water
● All the packages and parcels can be left in sunlight and should be disinfected
either by wipes or spray before touching .
● Disinfecting the knobs of highly used doors and cabinets can be done twice in a
day

30. PREVENTIVE MEASURES FOR
TRAVELLING
● AT THE FIRST PLACE AVOID TRAVELING! GO OUTSIDE ONLY IF
REQUIRED!
● Opt for the mode of travel which is the fastest and safest which
reduces the chances of exposure to the virus .
● Carry yourself with a bag of sanitization aids (Handrub,wipes ,spray
etc.)
● Maintaining distance should be the priority
● Refrain use of washrooms

separators to avoid spreading of virus

43. PREVENTIVE MEASURES AT
SCHOOLS/COLLEGES
SOME OF THE MOTIVES OF PREVENTIONS:
Testing, Screening, and Outbreak Response.
Testing to diagnose COVID-19 is one component of a comprehensive strategy and should be used in conjunction with
promoting behaviors that reduce spread, maintaining healthy environments, maintaining healthy operations, and
preparing for when someone gets sick.
Contact tracing Facility.
It is system that allows the detection of the infection chain and also helps in preventing further spread.
Plan and Prepare alternative ways of classes .
To keep alternative methods and plans of target shift plans ready if the number of cases increase in a school
/colleges . Promote online classes and come up with fair methods of online examination.

51. Personal Protective Equipment
● Personal protective equipment, or PPE, is designed to provide protection from
serious injuries or illnesses resulting from contact with chemical, radiological,
physical, electrical, mechanical, or other hazards.
● TYPES OF PPE:
Level A: protection should be worn when the highest level of respiratory, skin,
eye and mucous membrane protection is needed
Level B protection should be selected when the highest level of respiratory
protection is needed, but a lesser level of skin and eye protection is needed
Level C protection should be selected when the type of airborne substance is
known, concentration measured, criteria for using air-purifying respirators
met, and skin and eye exposure is unlikely
Level D protection is primarily a work uniform and is used for nuisance
contamination only. It requires only coveralls and safety shoes/boots

53. Professional-Grade Medical Mask / N95
1. N95 respirators and other professional-
grade medical masks are carefully sized
to form a tight seal between the air
outside and the face. They are designed
to protect healthcare workers from
droplets in the air.
2. Respirators are highly effective when
professionally fitted.
3. N95s are currently considered an
essential but scarce supply for healthcare
workers.

61. VACCINES

62. HOW VACCINES ARE MADE?
REFERENCE:https://www.cdc.gov/

63. COVAX:
● The vaccines pillar of the ACT-Accelerator, convened by CEPI GAVI and
WHO, is speeding up the search for an effective vaccine for all countries. At
the same time, it is supporting the building of manufacturing capabilities, and
buying supply, ahead of time so that 2 billion doses can be fairly distributed
by the end of 2021. Led by CEPI GAVI and WHO
● The COVAX pillar is focussed on the latter. It is the only truly global solution to
this pandemic because it is the only effort to ensure that people in all corners
of the world will get access to COVID-19 vaccines once they are available,
regardless of their wealth.

64. COVID-19 VACCINES AVAILABLE
Under clinical trials
As of December 28, 2020, large-scale (Phase 3) clinical trials are in progress or being
planned for three COVID-19 vaccines in the United States:
● AstraZeneca’s COVID-19 vaccine
● Janssen’s COVID-19 vaccine
● Novavax’s COVID-19 vaccine
Authorized and Recommended Vaccines
Currently, two vaccines are authorized and recommended to prevent COVID-19:
● Pfizer-BioNTech COVID-19 vaccine
● Moderna’s COVID-19 vaccine

65. TYPES OF COVID-19 VACCINE
Currently, there are three main types of COVID-19 vaccines that are or soon will be
undergoing large-scale (Phase 3) clinical trials
1. mRNA vaccines contain material from the virus that causes COVID-19 that gives our
cells instructions for how to make a harmless protein that is unique to the virus
2. Protein subunit vaccines include harmless pieces (proteins) of the virus that cause
COVID-19 instead of the entire germ
3. Vector vaccines contain a weakened version of a live virus—a different virus than the
one that causes COVID-19—that has genetic material from the virus that causes
COVID-19 inserted in it (this is called a viral vector).
Most COVID-19 Vaccines Require More Than One Shot
All but one of the COVID-19 vaccines that are currently in Phase 3 clinical trials in the
United States use two shots. The first shot starts building protection. A second shot a few
weeks later is needed to get the most protection the vaccine has to offer.

66. COVID-19 VACCINES IN INDIA
COVAXINTM, India's indigenous COVID-19 vaccine by Bharat
Biotech is developed in collaboration with the Indian Council of
Medical Research (ICMR) - National Institute of Virology (NIV). The
indigenous, inactivated vaccine is developed and manufactured
in Bharat Biotech's BSL-3 (Bio-Safety Level 3) high containment
facility.
The vaccine received DCGI approval for Phase I & II Human
Clinical Trials and the trials commenced across India from July,
2020.
After successful completion of the interim analysis from the
Phase 1 & 2 clinical trials of COVAXINTM, Bharat Biotech received
DCGI approval for Phase 3 clinical trials in 26,000 participants in
over 25 centres across India

75. CONCLUSION
● Getting vaccinated is one of many steps you can take to protect yourself
and others from COVID-19. Protection from COVID-19 is critically important
because for some people, it can cause severe illness or death.
● Stopping a pandemic requires using all the tools available. Vaccines work
with your immune system so your body will be ready to fight the virus if you
are exposed. Other steps, like masks and social distancing, help reduce
your chance of being exposed to the virus or spreading it to others.
Together, COVID-19 vaccination and following prevention’s we can defeat
COVID-19
