Are you immune to COVID-19 if you get it once?
Research is still ongoing into how strong that protection is and how long it lasts.
WHO is also looking into whether the strength and length of immune response depends on the type of infection a person has: without symptoms (‘asymptomatic’), mild or severe.
Even people without symptoms seem to develop an immune response..
Is there a Covid-19 variant?
The UK has identified a fast-spreading new variant of coronavirus that is 70% more transmissible than existing strains.
Do some people feel bad after getting the Covid vaccine?
Yes, the COVID-19 vaccine might make you feel ill. That means it’s working. The COVID-19 mRNA vaccines work by eliciting an immune response. That comes with some temporary side effects, like muscle aches or fever.
Can the coronavirus disease spread through sewage?
There is no evidence that the COVID-19 virus has been transmitted via sewerage systems with or without wastewater treatment.
Can drinking alcohol help in preventing COVID-19?
Alcohol does not protect against COVID-19; access should be restricted during lockdown.
Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?
See full answerAt the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.
Will climate change make the COVID-19 pandemic worse?
See full answerThere is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.However, climate change may indirectly affect the COVID-19 response, as it undermines environmental determinants of health, and places additional stress on health systems. More generally, most emerging infectious diseases, and almost all recent pandemics, originate in wildlife, and there is evidence that increasing human pressure on the natural environment may drive disease emergence. Strengthening health systems, improved surveillance of infectious disease in wildlife, livestock and humans, and greater protection of biodiversity and the natural environment, should reduce the risks of future outbreaks of other new diseases.
How is the new variant of Covid different?
The variant, called B.1.1.7., has a handful of mutations in its genetic code. Some of these mutations slightly alter the virus’s so-called spike protein, which allows it to bind to and infect cells. These alterations to the spike protein could potentially make the virus spread easier.
Who should not get the Covid vaccine?
The FDA put only one group in the category of those who should not get the vaccine: people who have a known history of a severe allergic reaction to any component of the Pfizer/BioNTech vaccine.
Do COVID-19 and tuberculosis spread in the same way?
See full answerTB bacilli remain suspended in the air in droplet nuclei for several hours after a TB patient coughs, sneezes, shouts, or sings, and people who inhale them can get infected. The size of these droplet nuclei is a key factor determining their infectiousness. Their concentration decreases with ventilation and exposure to direct sunlight.COVID-19 transmission has primarily been attributed to the direct breathing of droplets expelled by someone with COVID-19 (people may be infectious before clinical features become apparent). Droplets produced by coughing, sneezing, exhaling and speaking may land on objects and surfaces, and contacts can get infected with COVID-19 by touching them and then touching their eyes, nose or mouth . Handwashing, in addition to respiratory precautions, are thus important in the control of COVID-19.
When do Covid vaccine side effects start?
The side effects of the vaccine typically start within 12 to 24 hours of vaccination, but it may be difficult to tell the two apart if you become infected between vaccine doses. If you experience side effects that last beyond 48 hours, you should contact your doctor or medical provider for advice.
Are children with underlying health conditions at higher risk for COVID-19?
Current evidence suggests that people with underlying conditions such as chronic respiratory illness including asthma (moderate-to-severe), obesity, diabetes or cancer, are at higher risk of developing severe disease and death than people without other health conditions. This also appears to be the case for children, but more information is still needed.
Will the Covid vaccine work on the new strain?
At a separate press conference on Monday, the U.K. government’s chief scientific adviser, Patrick Vallance, said there is no evidence to suggest that vaccines wouldn’t work against the new strain. “The vaccine looks as though it should be as effective, and that’s obviously being looked at,” Vallance added.
Can the coronavirus spread via feces?
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.
Can the coronavirus disease be transmitted in hot or humid climates?
From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
What is the incubation period of the coronavirus disease?
The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.
Can COVID-19 be transmitted through feces or urine?
SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been no published reports of transmission of SARS-CoV-2 through feces or urine.
Who is at a higher risk to get infected with COVID-19?
COVID-19 is often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes or conditions that affect their immune system.
Should children wear a mask during the COVID-19 pandemic?
See full answerWHO advises that people always consult and abide by local authorities on recommended practices in their area. An international and multidisciplinary expert group brought together by WHO reviewed evidence on COVID-19 disease and transmission in children and the limited available evidence on the use of masks by children.Based on this and other factors such as childrens’ psychosocial needs and developmental milestones, WHO and UNICEF advise the following:Children aged 5 years and under should not be required to wear masks. This is based on the safety and overall interest of the child and the capacity to appropriately use a mask with minimal assistance.
Should I wear a mask after getting the COVID-19 vaccine?
Even after you get your two jabs, you should wear a mask and avoid crowds and situations where you could spread the virus to a lot of other people.
What does it mean to flatten the COVID-19 curve?
A flatter curve is created by a more gradual increase in the number of cases per day and a more gradual decrease. Over a long period of time the number of people infected might be around thesame, but the difference is the number of cases that occur each day.
