The newly identified CoronaVirus has triggered a pandemic of pneumonia-causing disease, not to mention an intense strain on health systems, mayhem on financial markets, a global economic malaise and a surfeit of misinformation.
10 Most Asked Questions about CoronaVirus
Take this answers and see if you’re up to date with the prevailing wisdom on COVID19, its impact on lives and how to stop it.
01. How long does the novel CoronaVirus survive outside the body?
A week in the air and on surfaces? NO.
Up to a two and a half weeks? NO.
Several hours of day? YES.
The virus that causes Covid-19 is stable for several hours in tiny floating particles, known as aerosols, and up to two to three days on plastic and stainless steel, U.S. researchers showed.
A study published in the New England Journal of Medicine in March concluded that the novel coronavirus can survive four hours on copper, 24 hours on cardboard, 48 hours on stainless steel and 72 hours on plastic.
02. What’s more important for preventing infection?
Wearing face mask? NO.
Using hand gloves? NO.
Frequent hand-washing? YES.
A mask should without help be worn by health workers, caregivers and individuals behind respiratory symptoms such as a fever or cough, according to health authorities.
There’s no beatific evidence masks protect unidentified, healthy people going just about their daily matter (although a few little studies have suggested that widespread use of direction masks by the public may have condensed transmission in outbreaks of toting going on respiratory diseases).
With masks in rapid supply, the to-do is that everyone is improved off if they are reserved for those who cant avoid aeration to people who are mixed or might be.
Because, viruses like this one are most efficiently go ahead via hands, frequent and thorough hand-washing and airing is the best habit to minimize the risk of infection.
The use of alcohol-based sanitizer is a pleasing second best, according to David Powell, a physician and medical helper to the International Air Transport Association.
Other useful trial adjoin avoiding agonized your twist, coughing or sneezing into the crook of your elbow and disposing of any used tissues deliberately.
03. What percentage of people confirmed to have Covid-19 develop mild or moderate symptoms?
20 percent of people? NO.
40 percent of people? NO.
80 percent of people? YES.
Countries are testing widely for CoronaVirus are finding that the number of misrepresented people who be alert-act no or delayed symptoms may be again previously thought.
Typical signs and symptoms append fever, dry cough, fatigue, phlegm or sputum production, sore throat and headache. About 14% of cases are coarse, causing terseness of breath and complexity animated.
Critical cases, which account for 6% of patients, experience respiratory failure, septic shock, and/or merged organ dysfunction or failure.
04. What is a fomite?
A hospital-grade disinfectant? NO.
An immunity-boosting supplement? NO.
A contaminated object or surface? YES.
A fomite is an inanimate surface or object, such as a doorknob or utensil, that can transmit infectious organisms.
For households with a suspected or confirmed case of infection, the U.S. Centers for Disease Control and Prevention suggest keeping the person separate from others as much as possible and daily cleaning and disinfecting of “high-touch surfaces” in common areas, such as light switches, tables and remotes.
05. What’s a safe distance to stay apart from someone who’s sick?
At least 1 foot (30 cm)? NO.
At least 2 feet (60 cm)? NO.
At least 3 feet (1 meter)? YES.
The COVID19 virus can fee via respiratory droplets spatters of liquid that are sometimes visible to the naked eye belligerently expelled by an tainted persons cough or sneeze.
The particles are usually oppressive sufficient to decrease suddenly to the auditorium or surrounding surfaces, which is why the WHO advises staying on summit of 1 meter (3 feet) away from a person who is poorly.
It recommends adjoining shaking hands, hugging and kissing for the become earliest brute forward infection can occur if virus-containing droplets submission the mouth, nose or possibly eye of someone manageable either directly or via an unwashed hand that’s touched a fomite.
06. Who’s at highest risk of developing severe Covid-19 disease?
Pregnant women? NO.
People over 60 years of age? YES.
Those with existing medical conditions? YES.
People of all ages can be infected by the new CoronaVirus. However, older people and those with medical conditions, such as high blood pressure, diabetes, asthma and cancer, are at greatest risk.
Children are among those with the lowest risk of developing severe symptoms, yet emerging evidence suggests that infants and toddlers may also be at risk of severe complications.
And data from the U.S. and Europe show young people, from 20-somethings to those in their early 40s, are among those falling seriously ill. Unlike with influenza, COVID19 doesn’t appear to cause more severe symptoms in pregnant women.
07. Can my pet give me COVID19?
Can my dog give me COVID19? NO.
Can my cat give me COVID19? NO.
Can my horse give me COVID19? NO.
There have been at least two instances of dogs being infected, but there is no evidence that a dog, cat or any pet can transmit the novel CoronaVirus, which is mainly spread through droplets produced when an infected person coughs, sneezes or speaks.
The finding that a dog may become infected isn’t all that surprising since the virus is believed to originate in bats, the only flying mammal, and may have crossed the species barrier to humans through another, intermediate mammalian host.
The answer is YES.
The evidence so far indicates the virus can be transmitted in all weather conditions.
A handful of researchers have prepared analyses on the subject, but none has yet been published in scholarly journals. Two research groups concluded that the places where CoronaVirus infection has mostly taken hold so far- such as Wuhan in central China, Milan and Seattle – similarly share mild humidity and temperatures.
Other researchers who examined outbreaks in 100 Chinese cities found that high temperatures and high relative humidity significantly reduce the transmission of the COVID19 virus.
Still other scientists in the U.S. concluded that weather changes alone won’t necessarily reduce the number of cases.
09. How much money have the world’s governments and central banks pledged in stimulus to counter the economic shock of the virus?
Of course, it’ $1 trillion? NO.
Almost $2 trillion? NO.
At least $3 trillion? YES.
Officials want to limit the depth and duration of an anticipated global recession, and they’re employing measures from interest rate cuts to support for companies and households in order to do it.
The U.S. is currently grappling with how to finance a $1.3 trillion stimulus package, while the European Central Bank has launched a 750 billion euro ($810 billion) debt-buying program to keep borrowing costs in check.
10. How soon can a vaccine for COVID19 be commercially available?
Of course in 16 weeks. NO.
Around 6 months. NO.
At least 12 months? YES.
It will take a year or more for experimental vaccines to undergo rigorous testing required for regulatory approval.
Two drugs being tested on patients in China have yielded mixed results. An HIV pill, marketed by AbbVie as Kaletra, that combines the chemicals lopinavir and ritonavir didn’t improve the condition of severe COVID19 patients or prevent them from dying more than standard care in a randomized, controlled trial of 199 patients.
A separate study of 80 patients receiving Fujifilm’s favipiravir, or Avigan, indicated that it might help clear the virus from patients a week earlier than the HIV medicine and was associated with improved chest symptoms shown on CT scans. Results are yet to be published for another antiviral, the experimental drug remdesivir, which is also undergoing clinical trials in China.
