Are public systems for disinfecting individuals (spraying in tunnels or chambers) recommended?

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.

What areas should be prioritized for disinfection in non-health care settings during the COVID-19 pandemic?

Disinfection practices are important to reduce the potential for COVID-19 virus contamination in non-healthcare settings, such as in the home, office, schools, gyms, publicly accessible buildings, faith-based community centres, markets, transportation and business settings or restaurants. High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.

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.

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 are the recommendations on use of disinfectants to prevent the spread of the coronavirus disease?

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.

What are the cleaning and disinfection recommendations during the COVID-19 pandemic?

Regular cleaning plays a vital role in limiting the transmission of COVID-19.

Reducing clutter and removing difficult to clean items can make cleaning easier. Increase the frequency of cleaning, using standard cleaning products such as detergents and bleach, paying attention to all surfaces but especially ones that are touched frequently, such as door handles, light switches, work surfaces, remote controls and electronic devices.

As a minimum, frequently touched surfaces should be wiped down twice a day, and one of these should be at the beginning or the end of the working day. Cleaning should be more frequent depending on the number of people using the space, whether they are entering and exiting the setting and access to handwashing and hand-sanitising facilities. Cleaning of frequently touched surfaces is particularly important in bathrooms and communal kitchens.

How does fresh air help to prevent the spread of COVID-19?

Bringing fresh air into a room and removing older stale air that contains virus particles reduces the chance of spreading COVID-19. The more fresh air that is brought inside, the quicker any airborne virus will be removed from the room.

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.

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 the coronavirus disease spread through the air in rooms?

In poorly ventilated rooms the amount of virus in the air can build up, increasing the risk of spreading COVID-19, especially if there are lots of infected people in the room. The virus can also remain in the air after an infected person has left.

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 the COVID-19 treatment Paxlovid approved in the UK?


The MHRA's Conditional Marketing Authorisation for Paxlovid is valid in Great Britain only. An emergency use authorisation has been granted for Northern Ireland to ensure access across the whole of the United Kingdom. Both authorisations were made on the basis of the same rigorous evaluation.

What is recommended to do to reduce the risk of COVID-19 in the workplace?

Keeping workplaces clean reduces the risk of infection and can reduce sickness in a workforce. It's especially important to clean surfaces that people touch a lot.

Staff can be supported to maintain a clean working environment by providing them with cleaning products, soap and hot water, and/or sanitiser.

What protective measures should I take while using disinfectants?

• The disinfectant and its concentration should be carefully selected to avoid damaging surfaces
and to avoid or minimize toxic effects on household members (or users of public spaces).
• Avoid combining disinfectants, such as bleach and ammonia, since mixtures can cause
respiratory irritation and release potentially fatal gases.
• Keep children, pets and other people away during the application of the product until it is dry and
there is no odour.
• Open windows and use fans to ventilate. Step away from odours if they become too strong.
• Disinfectant solutions should always be prepared in well-ventilated areas.
• Wash your hands after using any disinfectant, including surface wipes.
• Keep lids tightly closed when not in use. Spills and accidents are more likely to happen when
containers are open.
• Do not allow children to use disinfectant wipes. Keep cleaning fluids and disinfectants out of the
reach of children and pets.

What should be done in the event of a COVID-19 outbreak in a care home?


If a care home has an outbreak, this has impacts on visiting. In the event of an outbreak in a care home, the home should stop indoor visiting (except in exceptional circumstances such as end of life). All movements out of a setting should be minimised as far as possible.

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 you get the coronavirus disease (COVID-19) from packaging?

How can I improve ventilation in my home during the COVID-19 pandemic?

Opening windows and doors at home is the simplest way of improving ventilation for most people.

If windows have openings at both the top and the bottom (such as sash windows), using just the top opening will help incoming fresh air warm up as it mixes with room air, reducing cold draughts. In warmer weather, use both the top and bottom openings as this will help provide even more airflow.
