The DDM principle – disinfection, distance, masks – is still one of the most effective methods to avoid SARS-CoV-2 coronavirus infection. The British-Australian team of scientists has shown that by applying these principles, the risk of COVID-19 is reduced by more than half. However, the results should not discourage vaccination, the researchers urged.
The latest analysis of many studies shows that masks, distance and hand hygiene are effective in preventing infection and contracting COVID-19. Masks are especially useful, but vaccination against SARS-CoV-2 is essential.
Less risk of infection
The results of the meta-analysis have been published in the British Medical Journal. They include 72 studies conducted in relation to the usefulness of basic sanitary recommendations in the fight against infections such as masks, social distancing and hand hygiene (washing and disinfection). They show that all these methods of protection are effective and reduce the risk of infection as well as COVID-19.
The best results are achieved by using the masks, especially in closed rooms, they reduce the risk of SARS-CoV-2 infection by 53 percent. Keeping your physical distance reduces this risk by 25 percent.
– A review of research and a meta-analysis suggest that personal and social principles such as hand hygiene, wearing a mask and maintaining physical distance reduce the number of COVID-19 cases, argue the authors of the study – specialists from the Australian University of Monash and the University of Edinburgh, Scotland. They also point out that other protective measures, such as lockdown, closing borders, schools and workplaces, require further research to fully assess their effectiveness in fighting the pandemic. Based on the research conducted so far, it is not possible to present unequivocal conclusions. This may be due to difficulties in the methodology of the research, because the research that has been carried out so far is not always fully reliable.
If health rules are effective to protect against both COVID-19 and other infections such as seasonal flu, it does not mean that you don’t need to get vaccinated. Vaccinations provide the greatest protection against infectious disease, both from COVID-19 and the flu, although they do not always protect against the infection itself.
The authors of the study only point out that vaccination against COVID-19 alone may not be enough to fight the pandemic. Sanitary rules, such as wearing face masks, keeping distance and caring for your cancer, should still be followed after immunization. These rules reduce the dose of viruses to which we can be exposed in social contact. Thanks to this, the body can cope with them better, especially when we are vaccinated and our immune system is better prepared for it.
