COVID-19 is in the community. Given the nature of the disease there are no foolproof methods for protecting ourselves. The most we can do is reduce the chance of catching the virus in the public domain. These are some of the practical methods we can all take to protect ourselves from being infected with the virus.
Alcohol-based hand-sanitizers. The alcohol content must be at least 60% for the hand-sanitizer to be effective.
Wash your hands for 20 seconds, regularly (or as Boris Johnson recommends – 2 x Happy Birthday). Note that soap works ideally in combination with scrubbing and heat, but cold water works far better than nothing. You do not need antibacterial soap; the coronavirus is a virus, not a bacterium.
The current outbreak of COVID-19 is already challenging the habit of shaking hands. For the duration of the outbreak it is strongly suggested to avoid shaking hands or engage in any other forms of social greetings like kissing etc.
Touching your face
Not touching our faces seems to be the most effective method of reducing the chances of catching the virus from surfaces. We touch our faces nearly a 100 times a day and it is an unconscious habits. It is not the kind of habit that we can easily change just by making a decision to do it. If we persevere we can probably begin to see some change after 2-3 weeks of being aware of it. An easier way to reduce touching ones face is to wear plastic gloves. This both reduces the chances of picking up the virus in public, and reduce face touching.
Some people recommend not using the palms of your hands where using public facilities. It does seem reasonable that public handles would be a natural breeding ground for viruses. Try using elbows, the back of your hand, or paper, if you can, to avoid to much contact with handles.
Disinfecting common surfaces
You are much more likely to catch the virus from touching infected surfaces then through airborne contagion. The best way to avoid it is to clean surfaces in homes and offices, especially shared spaces, Countertops, remote controls, and refrigerator handles should be disinfected regularly.
