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.
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.
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.
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.

Is it recommended to fumigate outdoor surfaces during the COVID-19 pandemic?
In outdoor spaces, large-scale spraying or fumigation in areas such as streets or open market places for the COVID-19 virus or other pathogens is not recommended. Streets and sidewalks are not considered as routes of infection for COVID-19.
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.

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.

How long can the virus that causes COVID-19 survive on surfaces after being expelled from the body?
After being expelled from the body, coronaviruses can survive on surfaces for hours to days. If a person touches the dirty surface, they may deposit the virus at the eyes, nose, or mouth where it can enter the body and cause infection.
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%).
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 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.
Why are older people at significant risk of COVID-19?
Although all age groups are at risk of contracting COVID-19, older people face significant risk of developing severe illness if they contract the disease due to physiological changes that come with ageing and potential underlying health conditions.
Who issued the official name of COVID-19?
The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.
When was COVID-19 first reported?
On this website you can find information and guidance from WHO regarding the current outbreak of coronavirus disease (COVID-19) that was first reported from Wuhan, China, on 31 December 2019.
What is the minimum distance to be kept from each other to avoid COVID-19?
Be a hero and break the chain of COVID-19 transmission by practicing physical distancing. This means we keep a distance of at least 1m from each other and avoid spending time in crowded places or in groups.
What are the complications of COVID-19?
Complications may include pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and death.
What are some of the ways by which COVID-19 is transmitted?
COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors.
Who are at higher risk of developing serious illness from COVID-19?
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
When should health workers wear masks in the context of COVID-19?
In areas of community or cluster transmission, health workers, caregivers and visitors should wear a mask at all times when in the health facility, even if physical distancing can be maintained. Masks should be worn throughout their shifts, apart from when eating, drinking or needing to change the mask for specific reasons:• Health workers and caregivers include: doctors, nurses, midwives, medical attendants, cleaners, community health workers, and any others working in clinical areas.

What should be monitored after re-opening of schools during the COVID-19 pandemic?
See full answer
The following should be monitored:• effectiveness of symptoms-reporting, monitoring, rapid testing and tracing of suspected cases• the effects of policies and measures on educational objectives and learning outcomes• the effects of policies and measures on health and well-being of children, siblings, staff, parents and other family members• the trend in school dropouts after lifting the restrictions• the number of cases in children and staff in the school, and frequency of school-based outbreaks in the local administrative area and the country.• Assessment of impact of remote teaching on learning outcomes.Based on what is learned from this monitoring, further modifications should be made to continue to provide children and staff with the safest environment possible.
