How to prevent coronavirus spread?

Below is presented information on coronavirus spread prevention. Please remember that when you search for proven sources of knowledge based on scientific evidence, the best idea is to visit the websites of Chief Sanitary Inspectorate, Ministry of Health and National Health Fund.

1. Wash your hands frequently

Wash your hands frequently with water and soap. If this is not possible, you need to disinfect them with alcohol-based cleaners (minimum 60–70%). Washing your hands frequently reduces the risk of infection.

2. Avoid touching your eyes, nose and mouth

Coronavirus may be present on different surfaces and be transmitted when you touch them. Touching your eyes, nose or mouth with contaminated hands may cause transmission of virus from the surface to yourself.

3. Wash or disinfect the surfaces that you touch regularly 

The places which you often use should be disinfected carefully. Wipe regularly the desks, table tops, tables, handles, light switches and handrails with soap and water or disinfecting agent.

4. Disinfect your mobile phone regularly and do not use it during meals

Pathogens gather very easily on the surface of mobile phones. Disinfect your mobile phone regularly (e.g. with wet tissues soaked in disinfecting agent). Do not put your mobile phone on the table and do not use it during meals.

5. Keep safe distance from the person you are talking to 

Keep 1–2 metres of distance from the person who is coughing, sneezing or has a fever.

6. Apply protection rules when sneezing and coughing

Cover your mouth and nose with your bent elbow or tissue when coughing and sneezing. Then dispose of the tissue immediately in a closed waste bin and wash your hands, using soap and water, or disinfect them with alcohol-based cleaners (minimum 60-70%). Covering your mouth and nose when you cough and sneeze prevents germs and viruses from spreading.

7. Eat healthily and remember to keep your organism hydrated

Keep a balanced diet. Avoid highly processed food. Remember to eat at least 5 portions of vegetables and fruit a day. Keep your organism properly hydrated. Drink approximately 2 litres of liquids a day (mineral water is best). 

8. Use only proven sources of knowledge about coronavirus

Don't panic. Try to act reasonably in fighting coronavirus. Use only proven sources of knowledge based on scientific evidence, published on the websites of Chief Sanitary Inspectorate, Ministry of Health and National Health Fund.


How to prepare your own hand disinfection liquid  

Due to SARS-CoV-2 coronavirus threat, specialists from the Institute of Chemistry at the University of Silesia in Katowice prepare a hand disinfection liquid. The scientists say that everyone of us can prepare the virus-killing liquid at home! All you need is ethyl alcohol (e.g. spirit), glycerin, hydrogen peroxide and distilled/boiled water mixed in the right proportions (ultimately the alcohol content in the liquid should amount to 70-80%). However, the most important thing for us is to remember about the basic hygiene rules, such as washing our hands carefully.


To obtain detailed information about the characteristics and locations of SARS-CoV-2 coronavirus occurrence, as well as prevention related to COVID-19 disease epidemic, we recommend visiting the website of the Ministry of Health (HERE). 

To obtain detailed information on preparing disinfecting liquid, we recommend using the WHO guidelines available HERE.

Ingredients for preparing 100 ml of liquid:

  • 83.5 ml of ethyl alcohol (e.g. spirit 96%)
  • 4 ml of hydrogen peroxide
  • 1.5 ml of glycerin
  • 11 ml of distilled/boiled water

Mix the ingredients together following the order specified above, using proper measures and spoon/blade for mixing. The liquid should be stored in plastic or glass containers with tight closure (optionally with a doser). Each package should be properly labelled. 

Please be careful when preparing and using the liquid. Remember that ethanol is flammable and that you may be allergic to some of the ingredients.
