Outbreak and spread of the novel coronavirus  

Since the end of December 2019, a novel coronavirus has been spreading from the Hubei province in China and has reached many countries worldwide. Unlike an epidemic, which is a regionally occurring contagious disease, a pandemic is a worldwide epidemic. That is the case of this novel coronavirus, named recently SARS-CoV-21), which causes the disease COVID-19. You can find an overview of the coronavirus-risk areas on the WHO website (World Health Organisation).   

The virus spreads typically via small droplets which are spread when a person with COVID-19 coughs or exhales. Another person can then catch the virus by breathing in these droplets or touching objects contaminated by these droplets and then touching their eyes, nose or mouth2). The currently known incubation period is max. 14 days2).

What preventive measures to take

Containment can only be achieved through sensible behavior and the observance of general hygiene measures and especially of hand hygiene. Not all disinfectants are effective, while water and soap may be sufficient. Be aware to not mix disinfectants, as this can be very dangerous and follow each product’s instructions.

Reduce the risk of getting infected - tips for everyday life

Clean your hands frequently

Clean your hands with an alcohol-based hand rub or wash your hands thoroughly with soap and water, especially before preparing food, before eating, or when coming home. Always wash your hands after using the toilet or if your hands are visibly dirty. If you want to use a disinfectant, make sure that it is effective against enveloped viruses, thus SARS-CoV-2, and not only against bacteria. Learn here how to wash or disinfect your hands properly.

No handshaking or cheek kissing

Even if it seems rude at first, refrain from shaking hands with each other. Avoid physical contact in general.

Keep your hands away from your face

Pathogens can easily pass from your hands to the mucous membranes of your eyes, nose, and mouth. Avoid touching your face.

Hygienic coughing and sneezing

When coughing, “hand over mouth” is well intended, but in doing so you catapult a large number of viruses out of your body, which then sticks to your hands. So do not cough into your hands, but rather into your sleeve or a tissue.

Discard used tissues immediately

Throw used tissues into the trash right away – preferably into a container with a garbage bag that you can close tightly and dispose of regularly. Then wash your hands.

Ventilate regularly

In closed rooms, the number of viruses in the air can increase dramatically. Regularly ventilating a room (three to four times a day for ten minutes) counteracts this and thereby reduces the risk of infection. It also improves the indoor climate and prevents the mucous membranes of the mouth and nose from drying out.

Keep your distance and avoid crowds

Keep the greatest possible distance (at least 1.5 meter) from other people and avoid crowded places especially if you are over 60 of if you are affected by a medial condition. This avoids breathing in droplets, which can be spread by a coughing person who could be infected by the novel coronavirus.

Pay attention to first symptoms

If you have a fever, cough, or difficulty breathing, see a doctor as soon as possible. Important: Call beforehand so that you are directed straight to the right health facility and thus avoid coming into contact with too many people. Follow the directions of your local health authority.

Do not share objects

Avoid sharing objects and touching surfaces in public spaces as it is known that SARS-CoV-2 remains on surfaces4). If you think an object may be infected or contaminated, clean it using a surface disinfectant followed by washing your hands. Keep also in mind to desinfect your mobile phone espcially when you have used it outside your house. 

When to use a face mask

The WHO recommends wearing a face mask only when you are taking care of a person with suspected COVID-19 infection or when you are coughing or sneezing yourself. In this case, the mask is to protect people around you. If you wear a mask, you should know how to use it. The video explains when the use of a face mask is recommended and how it should be used.

Be on the safe side - avoid touching surfaces

It is not yet clear how long the novel coronavirus remains infectious on surfaces and objects. Studies suggest that it may persist for up to several days4. Therefore, we suggest that you avoid touching objects and clean your hands regularly. 

Keep these tips in mind if you need to leave the house

Grocery shopping

There is no way around it: When you go grocery shopping, you touch surfaces and items, including trolleys and baskets. Clean your hands with an alcohol based handrub when entering and leaving the store. Avoid in any case touching your face while you are shoppping and wash your hands thoroughly as soon as you arrive home. Wash purchased vegetables and fruits with water and disinfect the surface of other bought items. 

Making payments

Cards and cash could transfer the virus to your hands. However, card payment probably poses a lower risk, as you hold your own card and do not have to touch other people. Contactless bank transfers are also a good way to reduce any risk.

Objects in public

Frequently touched surfaces such as lift buttons and door handles in public places present a higher risk. We recommend that you avoid touching such surfaces by opening doors with your elbows or with your shoulder or using the stairs instead of the elevator whenever possible. After visiting the public bathroom, wash your hands with soap and water for 40 to 60 seconds. Also consider flushing the toilet with the lid lowered to prevent dropplets from being inhaled or contaminating close surfaces.
