Can we spray disinfectants on streets and sidewalks during the COVID-19 pandemic?
Streets and sidewalks are not considered as routes of infection for COVID-19. Spraying disinfectants, even outdoors, can be noxious for people’s health and cause eye, respiratory or skin irritation or damage.
What concentration of bleach should be used to disinfect surfaces from COVID-19 in non-health care settings?
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.
Is fumigation effective against the coronavirus disease?
In indoor spaces, routine application of disinfectants to environmental surfaces by spraying or fogging (also known as fumigation or misting) is not recommended for COVID- 19.One study has shown that spraying as a primary disinfection strategy is ineffective in removing contaminants outside of direct spray zones.

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.
Are public systems for disinfecting individuals (spraying in tunnels or chambers) recommended?
Spraying of individuals with disinfectants (such as in a tunnel, cabinet, or chamber) is not recommended under any circumstances. This practice could be physically and psychologically harmful and would not reduce an infected person’s ability to spread the virus through droplets or contact. Even if someone who is infected with COVID-19 goes through a disinfection tunnel or chamber, as soon as they start speaking, coughing or sneezing they can still spread the virus.

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.
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 are the guidelines for proper hygiene to protect against COVID-19?
See full answer
Don’t forget the basics of good hygiene • Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water. This eliminates germs including viruses that may be on your hands. • Avoid touching your eyes, nose and mouth. Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and infect you.• Cover your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately into a closed bin and wash your hands. By following good ‘respiratory hygiene’, you protect the people around you from viruses, which cause colds, flu and COVID-19. • Clean and disinfect surfaces frequently especially those which are regularly touched, such as door handles, faucets and phone screens.
How long does it take for symptoms of the coronavirus disease to appear?
On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
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.
Are smokers more likely to develop severe symptoms with COVID-19?
Current evidence suggests that the severity of COVID-19 disease is higher among smokers. Smoking impairs lung function, making it more difficult for the body to fight off respiratory disease due to the new coronavirus.Tobacco users have a higher risk of being infected with the virus through the mouth while smoking cigarettes or using other tobacco products. If smokers contract the COVID-19 virus, they face a greater risk of getting a severe infection as their lung health is already compromised.
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.

What are the strategies implemented for the control of the COVID-19 pandemic?
See full answerStrategies in the control of an outbreak are screening, containment (or suppression), and mitigation. Screening is done with a device such as a thermometer to detect the elevated body temperature associated with fevers caused by the coronavirus.[185] Containment is undertaken in the early stages of the outbreak and aims to trace and isolate those infected as well as introduce other measures to stop the disease from spreading. When it is no longer possible to contain the disease, efforts then move to the mitigation stage: measures are taken to slow the spread and mitigate its effects on the healthcare system and society. A combination of both containment and mitigation measures may be undertaken at the same time.[186] Suppression requires more extreme measures so as to reverse the pandemic by reducing the basic reproduction number to less than 1.[187].
Can people with mild COVID-19 symptoms recover at home?
People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
