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.
Are there face masks that should not be worn during the COVID-19 pandemic?
See full answer
Face 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.
Can masks prevent the transmission of COVID-19?
See full answer
Masks 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.

Should people wear masks while exercising during the COVID-19 pandemic?
People should NOT wear masks when exercising, as masks may reduce the ability to breathe comfortably.Sweat can make the mask become wet more quickly which makes it difficult to breathe and promotes the growth of microorganisms. The important preventive measure during exercise is to maintain physical distance of at least one meter from others.
What are the organs most affected by COVID‐19?
The lungs are the organs most affected by COVID‐19.
Which types of settings does COVID-19 spread more easily?
The “Three C’s” are a useful way to think about this. They describe settings where transmission of the COVID-19 virus spreads more easily:• Crowded places;• Close-contact settings, especially where people have conversations very near each other;• Confined and enclosed spaces with poor ventilation.

Can the coronavirus disease be transmitted through water?
Drinking water is not transmitting COVID-19. And, if you swim in a swimming pool or in a pond, you cannot get COVID-19 through water. But what can happen, if you go to a swimming pool, which is crowded and if you are close to other the people and if someone is infected, then you can be of course affected.
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.

Can you contract COVID-19 from touching surfaces?
People may also become infected by touching surfaces that have been contaminated by the virus when touching their eyes, nose or mouth without cleaning their hands. Further research is ongoing to better understand the spread of the virus and which settings are most risky and why.

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.

Can COVID-19 be transmitted through food?
There is currently no evidence that people can catch COVID-19 from food. The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food.
How should I wash fruits and vegetables in the time of COVID-19?
Wash fruit and vegetables the same way you would in any other circumstance. Before handling them, wash your hands with soap and water. Then wash fruits and vegetables thoroughly with clean water, especially if you eat them raw.
What is the best household disinfectant for surfaces during COVID-19?
Regular household cleaning and disinfection products will effectively eliminate the virus from household surfaces. For cleaning and disinfecting households with suspected or confirmed COVID19, surface virucidal disinfectants, such as 0.05% sodium hypochlorite (NaClO) and products based on ethanol (at least 70%), should be used.
