COVID-19 Diseases
About 3 years ago, when I and everyone were living our everyday lives as it always has been,
there was a virus called COVID-19 that ruined everyone's lives.There are Prevention from The
symptoms fever, chills, Cough, Shortness of breath, difficulty breathing fatigue, Muscle body
aches, Headache, New loss of taste or smell, sore throat, Congestion or runny nose, Nausea or
vomiting, diarrhea, Trouble breathing, Persistent pain or pressure in the chest, New confusion,
Inability to wake or stay awake, Pale, gray, or blue-colored skin, lips, or nail beds, depending on
skin tone which leads people to a even worst life to live.
However, According to what I read about, COVID-19 is a disease caused by SARS-CoV-2 that
can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract
(sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs). It spreads the same
way other coronaviruses do, mainly through person-to-person contact. Almost everyone one is
affected by COVID-19 but it does more to certain people about 20 percent or so. Researching
through CDC I learned that Since 31 December 2019 and as of week 2022-8, 435 882 971
cases of COVID-19 (in accordance with the applied case definitions and testing strategies in the
affected countries) have been reported, including 5 973 364 deaths
Based on the CDC, reported COVID-19 illnesses have ranged from mild (with no reported
symptoms in some cases) to severe to the point of requiring hospitalization, intensive care,
and/or a ventilator. COVID-19 illnesses can also lead to death.These disorders, also known as
post-acute sequelae of SARS-CoV-2 infection (PASC) or Long COVID, afflict people of all ages.
Fatigue, shortness of breath, difficulties concentrating, sleep disturbances, fevers, anxiety, and
depression are some of the long-term symptoms.COVID-19 (coronavirus illness 2019) is a
disease caused by the SARS-CoV-2 virus, which was first found in December of three years
ago. It is very contagious and has spread rapidly over the world. The United States now has the
most cases and deaths.
SARS-CoV-2 is the coronavirus that causes COVID-19. COVID-19 sickness appears to put
older folks and people with major underlying medical illnesses like heart or lung disease or
diabetes at a higher risk of having more serious complications. Exact vaccine ingredients vary
by manufacturer. Pfizer-BioNTech and Moderna COVID-19 vaccines also contain messenger
RNA (mRNA) and the Johnson & Johnson/Janssen COVID-19 vaccine contains a harmless
version of a virus unrelated to the virus that causes COVID-19. These give instructions to cells
in your body to create an immune response. This response helps protect you from getting sick
with COVID-19 in the future. After the body produces an immune response, it discards all the
vaccine ingredients just as it would discard any information that cells no longer need. This
process is a part of normal body functioning.
However, The immunological response to COVID-19 immunization is more predictable than
infection with the virus that causes COVID-19. Getting vaccinated against COVID-19 provides
most people with a high level of protection against the virus, and it can also provide further
protection for persons who have already been exposed to COVID-19. People who have already
had COVID-19 and do not get vaccinated after their recovery are more than twice as likely to
have COVID-19 again as those who get fully vaccinated after their recovery, according to one
study.
COVID-19 is prevented by all COVID-19 vaccinations now available in the United States.
COVID-19 infection can provide some protection against future sickness, which is referred to as
"natural immunity." However, the level of protection people receive from COVID-19 infection
varies depending on how mild or severe their illness was, the time since their infection, and their
age.
Getting vaccinated against COVID-19 is also a safer way to build immunity than getting sick with
COVID-19. COVID-19 vaccination protects you by eliciting an antibody response without
causing illness. Getting vaccinated may also protect those around you, especially those who are
at a higher risk of severe illness from COVID-19. Getting sick with COVID-19 can result in
severe illness or death, and we don't know who will get mild or severe illness. If you become ill,
you may infect others with COVID-19. You may also experience long-term health problems as a
result of COVID-19 infection.
New virus variants emerge as a result of the virus that causes COVID-19 constantly changing
due to a natural ongoing process of mutation (change). As the virus spreads, it has more
chances to evolve. High vaccination coverage in a population slows the spread of the virus and
helps prevent the emergence of new variants. The CDC recommends that everyone aged 5 and
up get vaccinated as soon as possible.
