Sumary of Human coronaviruses need organic materials to transfer efficiently between surfaces:
- The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly infected over 191 million individuals across the world since its emergence in late December 2019. The virus causes COVID-19 (coronavirus disease 2019), which alone is responsible for over 4.1 million deaths during this period, crippling the global economy.
- The study To shed more light on the transfer of viruses that might lead to infections, a recent study focused on whether human coronaviruses can transfer efficiently from contaminated hands to food or food contact surfaces.
- Researchers from the National Food Virology Reference Centre, Bureau of Microbial Hazards, Health Canada, and the University of Ottawa tested the transfer of viruses from the contaminated hands onto different surfaces.
- ” This study, published in the journal Viruses, indicated that human coronaviruses do not transfer effectively from contaminated hands to contact surfaces without the presence of any organic material.
- They employed three viruses in the study: two human coronaviruses, 229E and OC43, and murine norovirus-1 (MNV-1), as a surrogate for human norovirus, which is a contagious gastroenteritis-associated pathogen.
- “The use of surrogates allows for expanding the current knowledge of HCoV, without the need for more stringent biosafety measures required to work with the more pathogenic HCoVs,” observed the researchers in their paper.
- Related StoriesIn addition, they discussed the similar physicochemical and immunogenic properties of these viruses.
- The coronaviruses 229E and OC43, like SARS-CoV-2, are commonly associated with the common cold, typically characterized by rhinorrhea, nasal congestion, sore throat, sneezing, and cough, with or without fever.
