 • What is a Coronavirus?

Coronaviruses (CoV) are a broad family of viruses that can cause illnesses ranging from the
common cold to more serious conditions. The majority of virus-infected patients will
experience a mild to severe respiratory disease and will recover without the need for special
care. However, some people will get serious illnesses and need to see a doctor. Serious
sickness is more likely to strike older persons and those with underlying medical illnesses
including cancer, diabetes, cardiovascular disease, or chronic respiratory diseases. COVID-
19 can cause anyone to become very ill or pass away at any age. COVID-19 can be deadly,
and it has resulted in millions of deaths worldwide as well as long-lasting health issues in
some survivors.

• How did the coronavirus start?

Numerous investigations have been conducted to identify the origins of SARS-CoV-2, but none
of them have produced a definitive result. Middle East respiratory disease (MERS) and severe
acute respiratory syndrome (SARS) are caused by coronaviruses that originated in bats.

In Wuhan, China, the virus first surfaced on a limited scale in November 2019, followed by the
first significant cluster in December 2019. SARS-CoV-2 was initially believed to have
transitioned to humans at one of Wuhan, China's outdoor "wet markets." Later speculations
raised doubts that it might have started out as a biological weapon in a Chinese laboratory.
Viruses that originated in birds, pigs, bats, and other animals and transformed to become deadly
to people have been linked to several infectious disease epidemics in the past. More investigation
could possibly shed light on the processes by which the coronavirus changed through time to
become a pandemic illness.

 • How does the coronavirus spread?
The coronavirus is now understood to spread through respiratory droplets and virus particles that
are released when an infected person breathes, talks, laughs, sings, coughs, or sneezes. Small
infectious particles can persist in the air and build up indoors, especially in crowded areas with
inadequate ventilation, where larger drops may fall to the ground in a matter of seconds. This is
why protecting against COVID-19 requires the use of masks, good hand cleanliness, and
physical separation.

• What is the incubation period for COVID-19?

Within two to 14 days of being exposed to the virus, people begin to exhibit symptoms.
Depending on their immune system and the severity of their sickness, a person with the
coronavirus is contagious to others for up to two days before symptoms show up and for 10 to 20
days after that.

• What are symptoms of coronavirus?

o Cough
o Fever or chills
o Shortness of breath or difficulty breathing
o Muscle or body aches
o Sore throat
o New loss of taste or smell
o Diarrhea
o Headache
o New fatigue
o Nausea or vomiting
o Congestion or runny nose

• How is COVID-19 diagnosed?

Depending on where you reside, different criteria may be used to determine whether or not to
test you for the virus that causes COVID-19. Your clinic may need to screen you in order to
decide whether testing is necessary and accessible for you given your location. A healthcare
professional collects a sample from the nose (nasopharyngeal swab), throat (throat swab), or
saliva to test for the COVID-19 virus. The samples are subsequently delivered to a lab for
analysis. Sputum that you cough up may be sent for testing. At-home COVID-19 viral tests are
now permitted by the FDA. Only a doctor's prescription is required to purchase these. Based on
your signs and symptoms, as well as if you have had close contact with someone who has been
diagnosed with COVID-19, your health care provider will decide whether to order tests for the
virus that causes COVID-19 in the US. If you are more likely to develop a serious illness or are
having surgery, your doctor may also recommend testing for you.

Table 1: Total Number and Rate of Covid-19 Deaths by age group

Age group Total population Total deaths Total deaths per 100000
of population age group
0-14 1008900 0 0
15-24 618100 2 0
25-34 620000 5 0
35-44 776900 10 1
45-64 1201300 72 12
65-84 619000 587 191
85+ 77300 527 682

The total number of Covid-19 deaths and their rate are compared by age group in Table 1. The
age groups with the highest number of deaths attributable to Covid-19 as of May 8th were those
between 65 and 74 years old and those 85 years and beyond, with over 410 and over 530 deaths,
respectively. The total number of deaths among the younger population, defined as those
between the ages of 15 and 54, ranged from 2 to 20.
The age group 85 years and older had the highest fatality rate associated with Covid-19, with
over 680 deaths per 100,000 persons. At 1 per 100,000 persons, the death rate for people
between the ages of 25 and 34 was significantly lower.

• How is COVID-19 treated?

Antibiotics aren't effective against viral infections such as COVID-19. Many people
with COVID-19 may have mild illness and can be treated with supportive care. Supportive care
is aimed at relieving symptoms and may include:

o Pain relievers (ibuprofen or acetaminophen)

pg. 4
 o Cough syrup or medication

o Rest

o Fluid intake

Your medical professional might advise that you recover at home if your symptoms are minor.
To keep an eye on your symptoms and prevent the illness from spreading to others, you can
receive particular instructions. When you're sick, you'll probably be advised to keep as far away
from loved ones and pets as you can, wear a mask around them, and use a different bathroom and
bedroom. Additionally, maintain airflow in your home by opening windows and, when
appropriate, using air filters. During the COVID-19 epidemic, it's normal to feel scared and
worried. You're likely concerned that you or those you care about will fall unwell. You can be
worried about looking after sick people, including yourself. The antiviral medication remdesivir
(Veklury) has FDA approval to treat COVID-19 in hospitalized adults and children who are 12
years of age and older. Remdesivir may be prescribed for COVID-19 hospital patients who
require oxygen support or are at higher risk of developing serious disease. It is administered
through a skin-piercing needle. Another medication called molnupiravir has been approved by
the FDA to treat mild to moderate COVID-19 in people who are at increased risk of developing
serious disease and who are unable to take other treatments. The drug is swallowed whole as a
tablet.

• How do you protect yourself from this?

remember to take care of yourself and manage your stress.

o Eat healthy meals.

o Get enough sleep.
o Get physical activity.
o Try relaxation exercises such as deep breathing, stretching and meditation.
o Avoid watching or reading too much news.
o Connect with friends and family, such as with phone or video calls.

pg. 5
 o Do activities you enjoy, such as reading a book or watching a funny movie.

Maintaining other safety procedures, such as adhering to testing rules, using a mask, cleaning
your hands, and exercising physical distance, is also beneficial. Also, the COVID-19 vaccine
aids in the body's development of defenses against the COVID-19 virus. Even though the virus
that causes COVID-19 can occasionally infect vaccinated individuals, staying up to date on
COVID-19 vaccinations dramatically reduces the risk of developing severe illness, requiring
hospitalization, or passing away from COVID-19.
To sum up, corona virus caused a real crisis in education, economy, and healthcare. In addition,
it caused several deaths all over the world; that’s why, everyone should take the precautions
seriously. Moreover, regular hand washing, covering the mouth and nose while sneezing and
coughing, and properly cooking meat and eggs are all recommended methods for preventing the
transmission of infection. Including refraining from contact with anyone who exhibits respiratory
sickness symptoms, such as coughing and sneezing. If we want to put an end to the current
pandemic, it is crucial to immunize plenty of people. According to each nation's immunization
schedule and suggested age range for the vaccine, everyone should get vaccinated and should
urge others to do the same. There is a plan in place to prioritize vaccinations so that people who
need them most can receive them first, but there won't be enough vaccine accessible quickly
enough.
