Scientific argument for pathogens
Microorganisms with increased pathogenicity that require increased attention are represented in particular viruses such as coronavirus, human hepatitis virus type B, C (HBV, HCV) etc., but also bacteria (Staphylococcus Aureus, Escherichia coli, etc.), fungi (Aspergillus flavus, Aspergillus fumigatus, etc.) that prove increased resistance and pose problems in the costs of the protection and decontamination system.
Coronaviruses (CoVs) have traditionally been considered non-lethal pathogens, which caused only 15% of the usual colds, but yet in this century we have encountered a high pathogenicity in humans ever since 2003 in China - patients developing SARS (severe acute respiratory syndrome), and in 2012 in Saudi Arabia - MERS (middle east respiratory syndrome) which subsequently evolved towards an epidemic that spread worldwide with high morbidity and mortality. The current SARS-CoV-2 is the third largest pathogen in the CoV family to affect the human species, with the fastest pandemic spread in human history to date.
The results of the research showed that there is a genomic similarity of about 80% between SARS-CoV-2 and SARS-CoV. Therefore, the therapeutic schemes used to treat SARS and the methods used for decontamination of air and surfaces can be used as reference methodologies for the management of COVID-19.
