When hygiene matters most
The novel coronavirus, also known as SARS-CoV-2, is spreading worldwide. The main human-to-human transmission pathway appears to be droplet infection. With simple hygiene measures, each individual can help to protect themselves and others from the life-threatening lung disease and stem its rapid spread. Our topic special is dedicated to the most effective methods of protection against infection.
Where does the Coronavirus come from?
On 11 March 2020 COVID-19 was declared a pandemic by the World Health Organisation (WHO). The lung disease is caused by the coronavirus SARS-CoV-2. In contrast to an epidemic, the occurrence of an infectious disease in a pandemic is not localized and can spread across the entire globe, as can currently be observed. An infection with the corona virus manifests itself through flu-like symptoms such as coughing, fever, rhinitis and fatigue. Breathing problems, neck scratches, headaches and aching limbs, nausea, diarrhoea and chills are also possible. The course of the disease is individually different and varies greatly. Symptomless progressions are possible, as well as severe pneumonia with lung failure and death. Researchers assume that the corona pathogen SARS-CoV-2 was transmitted from a wild animal to a human being at a food market in the Chinese city of Wuhan (Hubei province). However, which animal originally carried the virus has not yet been clarified beyond doubt. At present, it is assumed that the pathogen was first transmitted from bats to other animals before it spread to humans - presumably by eating an animal that served as an intermediate host for the SARS-CoV-2 pathogen and was offered for sale at the market.
Trigger of infectious diseases
Infectious diseases can be caused by various pathogens, including viruses, bacteria or fungi.
How is the Coronavirus SARS-CoV-2 transmitted?
According to current knowledge, the corona pathogen SARS-CoV-2 is primarily transmitted via the so-called droplet infection. This involves people coughing or sneezing and distributing the pathogens in the air. Other people inhale these pathogens and, in the worst case, become infected with them as well.
Indirect transmission of the virus is also possible. People who have previously coughed or sneezed into their hands touch objects such as door handles, mobile phones, touch screens or chair backs. The viruses remain on the surface and reach healthy people from there.
Contact infection (smear infection):
Smear infection is also a way for viral diseases to spread. For example, even the smallest, contaminated residual traces of human stool can reach a healthy person via dirty hands. Infection is also possible if the pathogen enters the body directly via the mucous membranes of the eyes, throat and nose or the upper airways, for example through a kiss. It has not yet been finally clarified whether SARS-CoV-2 spreads via a smear infection. One of the most effective measures to prevent smear infection is to wash your hands thoroughly with standard soap.
How can you protect yourself and others from infection?
Since there is currently no vaccine against the coronavirus, it is very important to follow simple hygiene measures - both in private surroundings and in personal hygiene as well as in public spaces.
Why hygiene measures are so important in times of Corona
In a clean, well-maintained environment that is cleaned regularly, the risk of transmission of pathogens is minimised considerably. Surfaces are no longer a breeding ground for germs, bacteria or viruses. Even in places that are difficult to access, the pathogens are eliminated more thoroughly.
Cleaning measures for cleanliness and hygiene at home and in public places.
