Can COVID-19 cause severe disease?
While COVID-19 is spreading rapidly, most people will experience only mild or moderate symptoms.
That said, this coronavirus can cause severe disease in some people..
Can masks prevent the transmission of COVID-19?
See full answerMasks should be used as part of a comprehensive strategy of measures to suppress transmission and save lives; the use of a mask alone is not sufficient to provide an adequate level of protection against COVID-19.If COVID-19 is spreading in your community, stay safe by taking some simple precautions, such as physical distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue. Check local advice where you live and work. Do it all!Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal of masks are essential to make them as effective as possible.
Can COVID-19 be transmitted through water?
Fact: Water or swimming does not transmit the COVID-19 virusThe COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.
Is Covid-19 airborne?
The US Centers for Disease Control and Prevention (CDC) has recognised that SARS-CoV-2, the virus that causes COVID-19, is airborne and can be transmitted via respiratory fluids, which are fine droplets released during respiration.
Has COVID-19 been detected in drinking water supplies?
The COVID-19 virus has not been detected in drinking-water supplies, and based on current evidence, the risk to water supplies is low.
Are there face masks that should not be worn during the COVID-19 pandemic?
See full answerFace coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection. But, if the mask include an exhalation valve, a wearer that is infected (maybe without having noticed that, and asymptomatic) would transmit the virus outwards through it, despite any certification they can have.So the masks with exhalation valve are not for the infected wearers, and are not reliable to stop the pandemic in a large scale. Many countries and local jurisdictions encourage or mandate the use of face masks or cloth face coverings by members of the public to limit the spread of the virus.
When should masks be worn by the general public during the COVID-19 pandemic?
See full answerIn areas where the virus is circulating, masks should be worn when you’re in crowded settings, where you can’t be at least 1 metre from others, and in rooms with poor or unknown ventilation. It’s not always easy to determine the quality of ventilation, which depends on the rate of air change, recirculation and outdoor fresh air. So if you have any doubts, it’s safer to simply wear a mask.You should always clean your hands before and after using a mask, and before touching it while wearing it.While wearing a mask, you should still keep physical distance from others as much as possible. Wearing a mask does not mean you can have close contact with people.For indoor public settings such as busy shopping centres, religious buildings, restaurants, schools and public transport, you should wear a mask if you cannot maintain physical distance from others.
How should I properly wear a mask during COVID-19?
Here are the basics of how to wear a mask:• Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.• Make sure it covers both your nose, mouth and chin. • When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin.• Don’t use masks with valves.
How can you protect yourself and others from COVID-19?
clean hands regularly, prevent droplets from spreading (wearing masks, covering coughs and sneezes), keep at least one metre apart, limit time in enclosed or crowded spaces, clean frequently touched objects and surfaces, and respond appropriately if experiencing COVID-19-like symptoms.
Does wearing a mask mean you can have close contact with people during the COVID-19 pandemic?
Wearing a mask does not mean you can have close contact with people. For indoor public settings such as busy shopping centres, religious buildings, restaurants, schools and public transport, you should wear a mask if you cannot maintain physical distance from others.
Can the coronavirus disease spread through feces?
The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.
In what conditions does COVID-19 survive the longest?
Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).
How long does the virus that causes COVID-19 last on surfaces?
Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.
What are the materials for making masks for the coronavirus disease?
Fabric masks should be made of three layers of fabric:Inner layer of absorbent material, such as cotton.Middle layer of non-woven non-absorbent material, such as polypropylene.Outer layer of non-absorbent material, such as polyester or polyester blend.
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.
