The anti-viral protection provided by the Shield is not the only part of your regime to remain healthy or prevent infection. It is vital to use the Shield in combination with the UK government issued guidelines and other respected organisations such as healthline.com who advise as follows:
Wash your hands frequently to prevent the spread of the virus. Aim for about 20 seconds of scrubbing with soap and water before rinsing.
Cover coughs and sneezes with your arm instead of your hands or direct them into a disposable tissue. Many viruses are highly contagious and easily spreads through the air if you cough or sneeze.
Eat healthily to boost your immune system. Though you might lose your appetite when you’re sick, eating small meals rich in fruits and vegetables will help give your body the strength it needs to fight off the virus.
Drink lots of fluids, especially water, tea, and low-sugar electrolyte drinks. Avoid alcohol and caffeine.
