How much face masks are effective
Graphene
mask inactivates corona viruses under sunlight
Researchers
from Hong Kong City have developed 80% anti-bacterial graphene masks, which
they claim can be raised by almost 100% by sun exposure for 10 minutes.
Preliminary studies have shown promising results in the elimination of two
types of corona virus. Their discovery was published on ACS Nano. Graphene is
known for its anti-bacterial properties. Researchers developed a laser-forming
graphene form and tested it in Ecoli. It has shown an effective anti-bacterial
effect of about 82%. Most E coli die after eight hours. Preliminary tests on
two types of human corona virus showed graphene that does not work more than
90% of the virus in five minutes and is almost 100% in 10 minutes under the
sun. The team also plans to test the graphene in the blood of Covid-19.
Masks
protect better than a vaccine would: CDC director
"The
most powerful public health tool" against the corona virus, Robert Red
field, director of the Centers for Disease Control and Prevention (CDC) in the
US, said face masks offer better protection against corona infection than
vaccines. The CDC is equivalent to the US and the Indian Council of Medical
Research (ICMR). The red camp was responding to questions from U.S. lawmakers
at a Senate Sub-committee meeting.
We
have clear scientific evidence that they are working, and they are our defense.
I would even say that this face mask is more proven to protect me from Covid
than when I was taking the Covid vaccine, ”said the red field. While the corona
vaccine is likely to be available early next year, if not by the end of the
year itself, no one currently knows how effective this vaccine will be.
Scientists and developers of vaccines have suggested that the first vaccines
may not work very well, and that we will be lucky if they protect at least 75%
of those vaccinated. Red field urged people to continue to wear masks even
after vaccinations were available, saying the epidemic could be controlled
immediately if the face was used everywhere.
Killing
coronavirus with UV light, without harming people
Studies
have shown that using ultraviolet C light with 222 nanometer waves (1 nanometer
half a billion meters) effectively kills SARS-CoV-2, the old Covid-19 virus.
Ultraviolet light of between two hundred and 280nmis waves known as ultraviolet
C light, or UVC. The use of 222 nm UVC light is safe near humans, said
Hiroshima University researchers, who published their study in the American
Journal of Infection Control. In vitro tests by investigators showed that 99.7%
of SARS-CoV-2 viral virus was killed after 30-second exposure to U22nm UVC
radiation. Tests were performed using a UVC lamp.
The
contaminated solution spread on the plate. Investigators let it dry before
placing a UV Clamp 24 cm above the surface of the plates. A length of 222 nm
UVC cannot penetrate the outer layer of the human eye, so it will not damage
the underlying cells. But the 254 nm UVC germicidal lamps harm produced human
tissue, and could only be used to make empty cells. Investigators are proposing
additional tests for the safety and efficacy of 222 nm UVC irradiation in
SARS-CoV-2 viruses in real world locations.
Sleep
apnoea may increase risk for Covid-19 patients
Among
the various factors that make certain groups of people particularly vulnerable
to the side effects of Covid-19, here are some other: sleep deprivation. This
is a condition that causes shortness of breath or shallow breathing, when a
person is asleep. New research has found that people who are diagnosed with sleep
apnea may have an increased risk of side effects from Covid-19. The conclusion
is based on a systematic review of studies that reported the effects of
Covid-19 patients who were also diagnosed with obstructive sleep apnea.
Researchers point out the need to continue investigating the effects of the
virus on those who have a sleep disorder and to better identify those who are
currently undiagnosed. The systematic review looks at 18 studies up to June
2020 - eight of which are closely related to the risk of death from Covid-19,
and 10 related to sleep apnea.

To prevent the spread of
COVID-19:
Clean
your hands often. Use soap and water, or an alcohol-based hand rub.
Maintain
a safe distance from anyone who is coughing or sneezing.
Wear a
mask when physical distancing is not possible.
Don’t
touch your eyes, nose or mouth.
Cover
your nose and mouth with your bent elbow or a tissue when you cough or sneeze.
Stay
home if you feel unwell.
If you
have a fever, cough and difficulty breathing, seek medical attention.
Calling
in advance allows your healthcare provider to quickly direct you to the right
health facility. This protects you, and prevents the spread of viruses and
other infections.
Masks -
Masks can help prevent the spread of the virus from the person wearing the mask
to others. Masks alone do not protect against COVID-19, and should be combined
with physical distancing and hand hygiene. Follow the advice provided by your
local health authority.
Self-care
If you
feel sick you should rest, drink plenty of fluid, and eat nutritious food. Stay
in a separate room from other family members, and use a dedicated bathroom if
possible. Clean and disinfect frequently touched surfaces.
Everyone
should keep a healthy lifestyle at home. Maintain a healthy diet, sleep, stay
active, and make social contact with loved ones through the phone or internet.
Children need extra love and attention from adults during difficult times. Keep
to regular routines and schedules as much as possible.
It is
normal to feel sad, stressed, or confused during a crisis. Talking to people
you trust, such as friends and family, can help. If you feel overwhelmed, talk
to a health worker or counselor.
How It Spreads
The virus
that causes COVID-19 is mainly transmitted through droplets generated when an
infected person coughs, sneezes, or exhales. These droplets are too heavy to
hang in the air, and quickly fall on floors or surfaces.
You can
be infected by breathing in the virus if you are within close proximity of
someone who has COVID-19, or by touching a contaminated surface and then your
eyes, nose or mouth.
