Viruses are elementary entities consisting of a single independent particle with a parasitic character. Therefore, they infect every type of living organism (including fungi and bacteria), using them as vectors to spread quickly under certain conditions. Frequently visited facilities are ideal for the proliferation and spread of viruses. Once deposited on a surface, many existing viral strains can survive for up to 35 days. That’s why the correct sterilization procedures and the use of appropriate products are crucial to prevent prevent and fight multiple epidemics.
If properly supported, our immune system can fight – at first – a viral attack, but to immunocompromised individuals common viruses such as Adenovirus, Enterovirus and Norwalk virus can pose a serious risk. Even viruses not considered particularly harmful such as Paramyxoviruses (which cause measles, among others), Rotavirus and Rubella virus, can have serious consequences. Not to mention virus infections considered now under control in the western world such as Hepatitis B, Hepatitis C and Poliovirus. The most likely reason behind their spread is the uncontrolled movement of people and goods, which is not regulated in countries where these viruses are not eradicated.
Among those widespread viruses are included HIV, Avian influenza and, recently, the SARS-CoV-2 pandemic.
