It
is challenging to know at early stages when you are infected by the novel
coronavirus that causes the COVID-19 disease. There is a most common and rare
symptom loss of smell that could signal you must be tested. According to
Harvard T.H. Chan School of Public Health epidemiologist Marc Lipsitch, the
virus could ultimately infect between 40% and 70% of the population worldwide.
Some people might show no symptoms at all but many of those cases would be
mild, while the prospect of being infected with a new virus can be devastating.
The most symptoms are fever, coughing and shortness of breath. These symptoms
usually appear between two days and two weeks of exposure to the virus. Doctors
recently added "loss of smell" as a potential symptom that may show
up alone without any other symptoms. As
the coronavirus outbreak continues to accelerate Globally creating serious
worry among people.
As
COVID-19 is an infectious disease and grows faster among the people coming in
close contracts. Therefore, the social distancing and self-isolation have come
out as the best methods to avoid the fast spread of the disease. Most of the
countries adopted the methods of lock-down to avoid the community transmission
to control the disease.
Even
after all the protective measure the disease is still fast spreading globally
and creating fear and worry in the entire world as till now there is no direct
medicine to cure the decrease. Therefore keeping in mind the current situation
it is recommended that each person should take proper care about himself and
his family and stay at home to save lives.
As
the coronavirus outbreak continues to accelerate in the U.S., cleaning supplies
are disappearing off the shelves and people are worried about every subway
rail, kitchen counter and toilet seat they touch. A new analysis found that the virus can
remain viable in the air for up to 3 hours, on copper for up to 4 hours, on
cardboard up to 24 hours and on plastic and stainless steel up to 72 hours.
This study was originally published in the preprint database medRxiv on March
11, and now a revised version was published March 17 in The New England Journal
of Medicine. What's more, SARS-CoV-2 RNA was found on "a variety of
surfaces" in cabins of both symptomatic and asymptomatic people who were
infected with COVID-19 on the Diamond Princess cruise ship, up to 17 days after
the passengers disembarked, according to a new analysis from the Centers for
Disease Control and Prevention (CDC). However, this was before disinfection
procedures took place and "data cannot be used to determine whether
transmission occurred from contaminated surfaces," according to the
analysis. In other words, it's not clear if the viral particles on these surfaces
could have infected people. Another study published in February in The Journal
of Hospital Infection analyzed several dozen previously published papers on
human coronaviruses (other than the new coronavirus) to get a better idea of
how long they can survive outside of the body.[1]
The
new coronavirus spreads mostly through person-to-person contact within about a
6-foot (1.8 meters) radius, according to the Centers for Disease Control and
Prevention (CDC). People with COVID-19, which is the disease caused by the
coronavirus, spread viral droplets, particles through coughing and sneezing.
The particles can land, on the face, in the mouth or nose of those nearby or by
touching a surface where the virus has recently landed and then touching one's
mouth, nose or eyes. Fortunately, ethanol, hydrogen-peroxide or bleach-based
cleaners are effective at killing those coronaviruses that do survive on
surfaces. Unlike some extremely
contagious pathogens, the virus is not thought to spread via smaller droplets
that can remain airborne for long periods. In a study of the stool samples of
those diagnosed with COVID-19 found that viral particles in those stools looked
viable under a microscope. "This means that stool samples may contaminate
hands, food, water, etc.," the China CDC wrote in the report. For
instance, if a person did not wash their hands after touching a surface
contaminated with infected stool residue, there is a chance they could become
infected if they touch their eyes, nose or mouth with their hands, Live Science
previously reported. To avoid catching the new coronavirus, health officials
recommend avoiding close contact with people who are sick. A facemask is not a
substitute for staying home when you are sick, Dr. William Schaffner, an
infectious disease specialist at Vanderbilt University in Tennessee, recommends
avoiding touching your eyes, nose and mouth. Frequent hand-washing — 20
seconds, with soap and water — and 60%-95% alcohol-based hand sanitizers can
kill the virus.[2]
As per the Journal of
the American Medical Association, as many as 98% of COVID-19 patients
who were hospitalized had a fever, between 76% and 82% had a dry cough, and 11%
to 44% reported exhaustion and fatigue. As per the current WHO ( World
Health Organisation ) reports the coronavirus pandemic has killed more than 75,000
people worldwide, most of them in Europe and USA. Most affected nations have
called for complete lockdown to stop spread of the deadly virus.
The WHO said on 25th March, 2020 that countries which
have locked down their populations to prevent the spread of the coronavirus
need to use the time to find and attack the virus.
With around 75,000 deaths globally, Italy is the most affected
country with 16,523 and Spain 13341, USA 10871, France 8911, UK 5373, Iran 3739
and China 3331 deaths the country where the initial outbreak occurred. The
United States has also seen the 10871 deaths but the highest number of infections
crossing 4 Lakhs.
Coronavirus has now spread to over 205 countries across the world
affecting billions of people. "Asking people to stay at home and shutting
down population movement is buying time, and reducing pressure on health
systems. On their own these measures won't extinguish epidemics," said WHO
Director-General Tedros Adhanom Ghebreyesus. [3]
Physicians work with state health departments and the CDC to
determine who should be tested for the new virus. However, the CDC also
recommends that people with COVID-19 or any respiratory illness monitor their
symptoms carefully. If you become ill with the said symptoms and think you have
been exposed to the virus, the CDC recommends calling your doctor first rather
than traveling to a clinic worsening shortness of breath is reason to seek
medical care, particularly for older individuals or people with underlying
health conditions.
The disease appears to become more severe with age, with the 30-
to 79-year-old age range predominating the detected cases in Wuhan, where the
outbreak began, according to a study in JAMA. Children seem to be at less risk
of suffering noticeable symptoms of the disease. However, a recent study of
2,000 children confirmed or suspected to have COVID-19 found that 6% developed
severe or critical illness. The detailed study is published in the March 16
issue of the journal Paediatrics.
In more serious cases of COVID-19, patients experience pneumonia,
which means their lungs begin to fill with pockets of pus or fluid. This leads
to intense shortness of breath and painful coughing.
Govts in various countries
have taken right decision to lock down. This is one of the best strategy to
control the further spread of the Corona Virus. But the problem is that few
people in general not observing it seriously and taking it casual. As per the
rampant growth of Coronavirus and affecting the serious health issues around
the world and in India the social distancing and self-isolation is the best
strategy to save yourself from Covid-19.
Therefore, the entire individuals globally in general are required
to take necessary precautions and take good care of themselves and their near
and dear ones to ensure well-being of their families and the society in large. Humanity
has overcome many difficult challenges and together we can overcome.
Lockdowns are now imposed
in several countries. But the people are required to follow the lock down
seriously and ensure the following to save themselves form the infection of
Coronavirus (Covid-19) and get the real benefits and satisfy the real objectives
of the lock-down.
Family should identify only one adult in a family for going out.
Only he or she should go out. NOBODY ELSE.
•ONE dress: Use only one dress and same dress every time you go
out. Use full-length dress. Don't mix this dress with your other dresses.
•ONE wallet: Use only one wallet. Don't mix these currency, coins
and cards with other which already are there at home.
•ONE shopping bag: Use only one and same shopping bag every time.
•ONE vehicle: Use same vehicle and key. Avoid public
transportation.
•ONE go: Avoid going out multiple times. Finish all your work in
one go.
Avoid taking mobile phone or restrict using it.
Avoid crowding and come back immediately once you finish your
work.
Use your non - dominant hand or elbow to open the door or push the
buttons.
Once you come back: Keep your dress, wallet, bags, keys in a
separate bag. Do not mix with others.
We must embrace the social distancing and self-isolation, always
wash our hands, face thoroughly before touching anything and anyone, and always
use N-95 Masks. Clean our mobile phone surface with sanitizer.
We must remember that we CAN'T AVOID exposure but definitely we
CAN severely reduce its spread and impacts to avoid community transmission. As
the community, transmission has the potential to create havoc globally. If we
can avoid the community transmission, we can definitely save the world from the
most difficult time of the last two centuries.
