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.

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.

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 recommended surfaces to clean and disinfect during the COVID-19 pandemic?

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.

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.

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.

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.

Do I have to sanitise food packaging?

Food packaging 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. You should still follow good hygiene practice by washing your hands after handling any outer packaging.

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.
Throw away disposable items like gloves and masks if they are used during cleaning. Do not clean and re-use.
Do not use disinfectant wipes to clean hands or as baby wipes.

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 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.

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.

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.

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.

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.

Can the coronavirus disease spread through food?

It is very unlikely that COVID-19 is transmitted through food. However, as a matter of good hygiene practice, anyone handling food should wash their hands often with soap and water for at least 20 seconds before doing so. Crockery and eating utensils should not be shared. Clean frequently touched surfaces regularly.

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 do you disinfect 'high touch' surfaces to lower the chance of spreading COVID-19 in a non-healthcare setting?

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.

All disinfectant solutions should be stored in opaque containers, in a well-ventilated, covered area that is not exposed to direct sunlight and ideally should be freshly prepared every day. In indoor spaces, routine application of disinfectants to surfaces via spraying is not recommended for COVID-19.

Can COVID-19 spread through sewage systems?

The World Health Organization is clear that the likelihood of coronavirus being transmitted via sewerage systems is extremely low or negligible.

Can COVID-19 spread through water while swimming?

Fact: Water or swimming does not transmit the COVID-19 virus

The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.

WHAT YOU CAN DO:

Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.

Can I have close contact with people if I'm wearing a mask during COVID-19?

While wearing a mask, you should still keep physical distance from others as much as possible. Wearing a mask does not mean you can have close contact with people.

How should you maintain social distancing to prevent the spread of COVID-19 at home with possible infection?

Spend as little time as possible in shared spaces such as kitchens, bathrooms and sitting areas. Avoid using shared spaces such as kitchens and other living areas while others are present and take your meals back to your room to eat. Observe strict social distancing.

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%).
