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.

Which surface disinfectants are recommended to reduce spread of COVID-19?

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 to decontaminate clothes from the coronavirus disease (COVID-19)?

Use the warmest water setting and dry items completely. Dirty laundry that has been in contact with an unwell person can be washed with other people's items. To minimise the possibility of dispersing virus through the air, do not shake dirty laundry prior to washing.

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 you contract COVID-19 by touching contaminated surfaces?

People could catch COVID-19 by touching contaminated surfaces or objects – and then touching their eyes, nose or mouth. If they are standing within one meter of a person with COVID-19 they can catch it by breathing in droplets coughed out or exhaled by them. In other words, COVID-19 spreads in a similar way to flu.

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%).

How should I wash clothes to prevent the spread of COVID-19?

To reduce the possibility of spreading the virus through the air, do not shake dirty laundry. Wash items in accordance with the manufacturer’s instructions. All dirty laundry can be washed in the same load. If you do not have a washing machine, wait a further 72 hours after your self-isolation has ended when you can then take the laundry to a public launderette.

Should I change my laundry routine according to the safety guidelines?

Items should be washed in accordance with the manufacturer’s instructions. There is no additional washing requirement above what would normally be carried out.

Should food packaging be washed clean during the coronavirus pandemic?

If you have been shopping, there should be no need to sanitise the outer packaging of food. This is because food businesses are required to have a system for managing food safety in place, which should include keeping packaging clean.

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.

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 can I protect myself and others when using disinfectants?

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.

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.

How long should I wash my hands during the COVID-19 pandemic?

Thorough hand hygiene after any cough or sneeze is required. The WHO also recommends that individuals wash hands often with soap and water for at least 20 seconds, especially after going to the toilet or when hands are visibly dirty, before eating and after blowing one's nose.

before and after handling raw foods like meat and vegetables
before eating or handling food
after blowing your nose, sneezing or coughing
before and after treating a cut or wound
after touching animals, including pets, their food and after cleaning their cages
Washing your hands properly removes dirt, viruses and bacteria to stop them spreading to other people and objects, which can spread illnesses such as food poisoning, flu or diarrhoea.

It can help stop people picking up infections and spreading them to others.

It can also help stop spreading infections when you're visiting someone in hospital or another healthcare setting.

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

The risk of imported food and packaging from affected countries being contaminated with coronavirus is very unlikely. This is because the law requires the exporter to follow the right controls during the packing and shipping process to ensure good hygiene is met.

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.

products.

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.

How long have coronaviruses existed?

The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.

Will climate change make COVID-19 worse?

There 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.

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.
