Ventilation, testing and face masks: Remain vigilant this winter to beat Covid-19

Sponsored Editorial: Produced in association with the UK Government

“Remain vigilant” are the UK Government’s stay safe watchwords as autumn and winter approach.

Together we can all continue to take key steps to contain coronavirus.

Our behaviour can reduce the risk of transmission and protect ourselves, friends and family as well as vital NHS services as the days become colder and nights darker.


As we move into colder months, increased infection rates are expected due to people mixing more freely as they return to work and education as well as socialising more indoors, where most coronavirus infections are spread.

Covid-19’s main transmission is airborne virus particles and as we now spend more time together inside, dangers of breathing in infectious particles increase significantly.

While vaccines and the booster jab remain our best defence, we can all still catch Covid-19 if vaccinated, putting loved ones’ health in danger, because one in three sufferers show no symptoms.

Coronavirus is spread through particles exhaled from noses and mouths of infected people as they breathe, speak or cough.

These linger “like smoke” in unventilated spaces.


Opening windows for 10 minutes, or a small amount continuously, makes a big difference as well as letting in fresh air into your home before, during and after visitors.

And we should still wear face coverings in enclosed spaces and within crowds.

It's also important to remember that NHS Test and Trace will continue to protect the public.

If you show symptoms, arrange a free PCR test as soon as possible and, if positive, self-isolate.

We should continue to regularly use rapid tests, which are free, easy and results are confirmed within 30 minutes.

These are available by visiting nhs.uk/Get-Tested, some pharmacies or by calling 119.

Before attending pharmacies, you should register at gov.uk/get-collect-code or call 119 for a code to show when you collect your test packs.

Over the course of the pandemic over 298 million PCR and rapid lateral flow tests have been conducted, which has identified over 7.8 million Covid-19 cases.

Reporting results at gov.uk/report-covid19-result helps quickly identify virus spread and outbreaks, allowing health chiefs to respond sooner.

If positive, you should immediately self-isolate and confirm your result by taking a PCR test, easily ordered online.

“Lateral flow devices are effective at finding people with high viral loads who are most infectious and most likely to transmit the virus to others,” explained Dr Susan Hopkins.

“It is a very good test,” confirmed the UK Health Security Agency’s Healthcare Epidemiologist Consultant in Infectious Diseases and Microbiology.



1. Ventilation

Let fresh air flow into indoor spaces, allowing Covid-19 particles to blow away.

Opening windows for a short time can help reduce such risks.

Meet family and friends outdoors when and wherever possible.


2. Testing

Use a Lateral Flow Device to test regularly, even if you don’t have symptoms, because one in three people suffering coronavirus don’t show any symptoms.

Consider testing if you feel there will be a period of higher risk that day, to yourself or others. Examples include...

  • Mixing in crowded indoor spaces, for example a nightclub
  • Visiting vulnerable people.

Taking a rapid lateral flow test before a period of higher risk gives you peace of mind that you are unlikely to be infectious with Covid-19, and it is unlikely you will spread the virus. If you do test positive, you can then take action to help stop the virus spreading. Let’s send our children back to school safely.

Your family and friends can get tested for free.


3. Face coverings

Keep wearing face coverings at all times within crowded spaces.
