How can contact tracing help in controlling the spread of COVID-19?

How can contact tracing help in controlling the spread of COVID-19?

Contact tracing can break the chains of transmission through the rapid identification, isolation and clinical care of cases, and providing supported quarantine of contacts, meaning that virus transmission can be stopped.

What is the benefit of contact tracing through the NHS COVID-19 app?

Contact tracing depends on being able to determine who a person who has tested positive for COVID-19 could have infected. Manual contact tracing involves asking an infected person to remember who they have been in contact with; the person can only identify the people they know. The app supports contact tracing through your phone, without needing to know anyone’s names or identities.

What are some ways to reduce the spread of COVID-19?

Social distancing, washing your hands and good respiratory hygiene (using and disposing of tissues), cleaning surfaces and keeping indoor spaces well ventilated are the most important ways to reduce the spread of COVID-19.

How does the COVID-19 contact tracing app work?

The contact tracing element of the app works by using low-energy Bluetooth to log the amount of time you spend near other app users, and the distance between you, so it can alert you if someone you have been close to later tests positive for COVID-19 – even if you don't know each other.

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 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.

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.

Does the NHS COVID-19 app track my location?

It does not record or track where you or other app users are (for example, at home or in a public space). The app does not identify you or your location to other app users (or, as noted above, the government).

Does NHS COVID-19 app show previous venues you have visited?

Details of which venues you have visited again are only on your app. The app will hold details of a relevant test result but only for as long as necessary, 14 days after any self-isolation period this data is no longer recorded.

Who provides contact-tracing information to the NHS for COVID-19?

The digital contact-tracing technology used in the NHS COVID-19 app is provided by Apple and Google. This technology is known as the 'Google Apple Exposure Notification system' (or ' GAEN '). GAEN , operating systems and data available from this system are constantly being refined.

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.

Can I get COVID-19 while swimming?

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 you get a COVID-19 vaccine if you are pregnant?

The Joint Committee on Vaccination and Immunisation ( JCVI ) has now advised that pregnant women are more at risk of severe COVID-19 disease. They are reminding pregnant women to have their COVID-19 vaccines as soon as possible. They should not delay vaccination until after they have given birth.

How does the NHS COVID-19 app protect users' anonymity while tracking the cases?

The app uses complex cryptography to protect you and other app users' anonymity while enabling diagnosis keys to be matched with a relevant broadcast key when relevant. Where there are matches, you will get an alert that you've been in contact with someone who tested positive.

Does the NHS COVID-19 app protect your privacy?

The app has been designed with user privacy in mind, so it tracks the virus, not people and uses the latest in data security technology to protect privacy. The system generates a random ID for an individual's device, which can be exchanged between devices via Bluetooth (not GPS).

These unique random IDs regenerate frequently to add an extra layer of security and preserve anonymity. The app does not hold personal information such as your name, address or date of birth, and only requires the first half of your postcode to ensure local outbreaks can be managed.

Will my data be deleted after uninstalling the NHS COVID-19 app?

If you choose to delete the app, you will not receive any notifications (alerts) from the app about coronavirus (COVID-19) and the data stored by the app on your phone will be deleted. If you decide to install the app again, you will need to provide the requested information again.

Does the COVID-19 app collect personal data?

• The app holds personal data, however, we do not collect personal data. For example, your app will hold details of the venues you have visited but this is not shared with us

What is a venue check-in on the NHS app?

Venue check-ins add a count of the venue check-ins during the 6-hour analytical period. Where the check-in fails or is abandoned this is counted as well. This data is used to ensure the QR venue check in is working as expected as well as give a sense of how app users are using the function and the potential impacts.

How often does the National Health Service (NHS) app update data?

The app is updated by the central systems (product environment), on average, every 2 hours. The central system provides all app users with three key sets of data. Every app user receives the same information, called reference material, which the app uses to determine if you need to receive an alert or advice. These are:

• the list of Diagnosis Keys from app users who have tested positive. This functionality keeps the identity of app users anonymous to other app users
• the list of all postcode districts and their current risk level
• the list of venues that could pose a risk, as determined by Health Protection Teams and the Joint Biosecurity Centre (JBC)

Does the NHS COVID-19 app store my IP address?

Your IP address (a unique identifier for your phone when you use the internet) is automatically shared with the Department for Health and Social Care (DHSC) when you share data through the App. DHSC does not use your IP address however and deletes it as soon as it is received. Like every other app, our app uses the internet to work which requires the use of the IP address.

The application is reviewed and tested to make sure that there never exists functionality that collects, logs, retransmits or stores the IP addresses received within HTTP headers. This minimises the possibility of recombining IP address and payload data.

How does the National Health Service (NHS) app prevent re-identification?

Only those with access to the app will have details of the venues checked into. No details about which venues a user has checked into is included in the analytical data set or provided to the use.

Can I delete the COVID-19 app?

Right to be forgotten. You can choose to delete the app and the data it contains.

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.

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 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.
