Can COVID-19 virus be transmitted through drinking-water?
See full answerAlthough persistence in drinking-water is possible, there is no evidence from surrogate human coronaviruses that they are present in surface or groundwater sources or transmitted through contaminated drinking water.
The COVID-19 virus is an enveloped virus, with a fragile outer membrane.
Generally, enveloped viruses are less stable in the environment and are more susceptible to oxidants, such as chlorine.
While there is no evidence to date about survival of the COVID-19 virus in water or sewage, the virus is likely to become inactivated significantly faster than non-enveloped human enteric viruses with known waterborne transmission (such as adenoviruses, norovirus, rotavirus and hepatitis A)..
Are smokers at higher risks of COVID-19?
See full answerA review of studies by public health experts convened by WHO on 29 April 2020 found that smokers are more likely to develop severe disease with COVID-19, compared to non-smokers. COVID-19 is an infectious disease that primarily attacks the lungs. Smoking impairs lung function making it harder for the body to fight off coronaviruses and other diseases. Tobacco is also a major risk factor for noncommunicable diseases like cardiovascular disease, cancer, respiratory disease and diabetes which put people with these conditions at higher risk for developing severe illness when affected by COVID-19.
Can you get the coronavirus disease from touching contaminated surfaces?
When someone who has COVID-19 coughs or exhales they release droplets of infected fluid. Most of these droplets fall on nearby surfaces and objects – such as desks, tables or telephones. People could catch COVID-19 by touching contaminated surfaces or objects – and then touching their eyes, nose or mouth.
Can food be contaminated with the virus that causes COVID-19?
It is highly unlikely that people can contract COVID-19 from food or food packaging. COVID-19 is a respiratory illness and the primary transmission route is through person-to- person contact and through direct contact with respiratory droplets generated when an infected person coughs or sneezes. There is no evidence to date of viruses that cause respiratory illnesses being transmitted via food or food packaging. Coronaviruses cannot multiply in food; they need an animal or human host to multiply
Does heat kill the coronavirus?
Heat at 56°C kills the SARS coronavirus at around 10000 units per 15 min (quick reduction).
How dangerous is the coronavirus disease?
Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.
Should coronavirus disease patients be isolated in hospitals?
WHO advises that all confirmed cases, even mild cases, should be isolated in health facilities, to prevent transmission and provide adequate care.But we recognize that many countries have already exceeded their capacity to care for mild cases in dedicated health facilities. In that situation, countries should prioritize older patients and those with underlying conditions.
Can the coronavirus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
What is the recovery time for the coronavirus disease?
Using available preliminary data, the median time from onset to clinical recovery for mild cases is approximately 2 weeks and is 3-6 weeks for patients with severe or critical disease.
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 spread in hot and humid climates?
See full answerFrom 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. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days.
What percentage of COVID-19 infections are severe?
For COVID-19, data to date suggest that 80% of infections are mild or asymptomatic, 15% are severe infection, requiring oxygen and 5% are critical infections, requiring ventilation.
Is coronavirus a bacteria or virus?
The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water.
How do viruses get their name?
Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV).
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.
Is headache a symptom of the coronavirus disease?
The virus can cause a range of symptoms, from ranging from mild illness to pneumonia. Symptoms of the disease are fever, cough, sore throat and headaches.
What is the risk of dying for the older people?
Over 95% of these deaths occurred in those older than 60 years. More than 50% of all fatalities involved people aged 80 years or older. Reports show that 8 out of 10 deaths are occurring in individuals with at least one comorbidity, in particular those with cardiovascular disease, hypertension and diabetes, but also with a range of other chronic underlying conditions.
Who is at risk for coronavirus?
See full answerThe virus that causes COVID-19 infects people of all ages. However, evidence to date suggests that two groups of people are at a higher risk of getting severe COVID-19 disease. These are older people (that is people over 60 years old); and those with underlying medical conditions (such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer). The risk of severe disease gradually increases with age starting from around 40 years. It’s important that adults in this age range protect themselves and in turn protect others that may be more vulnerable.WHO has issued advice for these two groups and for community support to ensure that they are protected from COVID-19 without being isolated, stigmatized, left in a position of increased vulnerability or unable to access basic provisions and social care.
