What kind of mask is recommended to prevent COVID-19 transmission?
Fabric masks are recommended to prevent onward transmission in the general population in public areas, particularly where distancing is not possible, and in areas of community transmission.
This could include the school grounds in some situations.
Masks may help to protect others, because wearers may be infected before symptoms of illness appear.
The policy on wearing a mask or face covering should be in line with national or local guidelines.
Where used, masks should be worn, cared for and disposed of properly..
How to stay hydrated during self-quarantine amid the COVID-19 pandemic?
See full answerWhenever available and safe for consumption, tap water is the healthiest and cheapest drink. It is also the most sustainable, as it produces no waste, compared to bottled water. Drinking water instead of sugar-sweetened beverages is a simple way to limit your intake of sugar and excess calories. To enhance its taste, fresh or frozen fruits like berries or slices of citrus fruits may be added, as well as cucumber or herbs such as mint, lavender or rosemary.Avoid drinking large amounts of strong coffee, strong tea, and especially caffeinated soft drinks and energy drinks. These may lead to dehydration and can negatively impact your sleeping patterns.
How can ventilation reduce the risk of contracting COVID-19 in airplanes?
Most airplanes have cabin air filtration systems equipped with HEPA filters which can remove viruses and germs quickly, minimizing how long people are exposed to any potential infectious virus or bacteria expelled by a cough or sneeze.
Who should not travel during the COVID-19 pandemic?
WHO adviceConfirmed, probable and suspected cases, and contacts of confirmed or probable cases should not travelPersons with any sign or symptom compatible with COVID-19 should not travel, unless COVID-19 diagnostic testing has been conducted and SARS-CoV-2 infection has been ruled out as the cause for illness
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.
Is it normal to experience pandemic fatigue during the COVID-19 pandemic?
In recent weeks, many countries have been reporting an increase in “pandemic fatigue” – people are feeling demotivated about following recommended behaviours to protect themselves and others from the virus.Finding effective ways to tackle this fatigue and reinvigorate public vigilance is a growing challenge as the crisis continues. Pandemic fatigue evolves gradually over time and is affected by the cultural, social, structural and legislative environment.
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.
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.
How can I help a family member with COVID-19 at home?
The ill person should stay in a separate room. If this is not possible, then keep at least a 1-metre distance from them. The sick person and anyone else in the same room should wear a medical mask.Provide good ventilation in the room of the ill person and shared spaces, and open windows if possible and safe to do so.
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.
Which organ is most affected by COVID-19?
The lungs are the organs most affected by COVID-19 because the virus accesses host cells via the enzyme angiotensin-converting enzyme 2 (ACE2), which is most abundant in type II alveolar cells of the lungs.
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 should I do if I feel unwell during the COVID-19 pandemic?
See full answer• Know the full range of symptoms of COVID-19. The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include loss of taste or smell, aches and pains, headache, sore throat, nasal congestion, red eyes, diarrhoea, or a skin rash.• Stay home and self-isolate even if you have minor symptoms such as cough, headache, mild fever, until you recover. Call your health care provider or hotline for advice. Have someone bring you supplies. If you need to leave your house or have someone near you, wear a medical mask to avoid infecting others.• If you have a fever, cough and difficulty breathing, seek medical attention immediately. Call by telephone first, if you can and follow the directions of your local health authority.• Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities.
What is the most likely ecological reservoirs for coronavirus disease?
The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.
How do I disinfect surfaces during the coronavirus disease pandemic?
In non-health care settings, sodium hypochlorite (bleach / chlorine) may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water). Alcohol at 70-90% can also be used for surface disinfection. Surfaces must be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection.Cleaning should always start from the least soiled (cleanest) area to the most soiled (dirtiest) area in order to not spread the dirty to areas that are less soiled.
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.
Is the coronavirus disease airborne transmitted?
According to current evidence, COVID-19 virus is primarily transmitted between people through respiratory droplets and contact routes. In an analysis of 75,465 COVID-19 cases in China, airborne transmission was not reported.
Is ventilation an important factor in preventing COVID-19 from spreading?
See full answerVentilation is an important factor in preventing the virus that causes COVID-19 from spreading. Recirculated air from split air conditioning units, fan coils or any system that runs with a recirculation mode should be avoided where possible, unless in a single occupancy room with no one else present. If recirculation is unavoidable, increase outdoor air exchange by opening windows, if possible and safe to do so, and minimize air blowing from one person directly at another.Floor or ceiling fans can provide ventilation when the people occupying the room are from the same household, but are not recommended when travelers from different households are together.
Can the COVID-19 survive in drinking water?
Currently, there is no evidence about the survival of the COVID-19 virus in drinking-water or sewage.
Should you meet with other people during the COVID-19 pandemic?
In this difficult period it is best to meet virtually but if you have to meet others, do it carefully and with the right precautions.
How should you behave in school during the COVID-19 pandemic?
Model good practices such as sneezing or coughing into your elbow and washing your hands, especially for younger family members. Don’t stigmatize your peers or tease anyone about being sick; remember that the virus doesn’t follow geographical boundaries, ethnicities, age or ability or gender.Tell your parents, another family member, or a caregiver if you feel sick, and ask to stay home.
