Viruses are elementary entities consisting of a single independent particle and are also obligate parasites. Therefore, they infect every type of living organism (including fungi and bacteria), using them as vectors to spread rapidly under certain conditions. Frequently visited facilities or areas have the ideal characteristics 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 a correct sterilization procedure and use of appropriate products are crucial for preventing and fighting 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 considered not to be particularly harmful such as Paramyxoviruses (which cause measles, among others), Rotavirus and Rubella virus can have serious consequences for these people, not to mention virus infections considered now under control in the western world such as Hepatitis B, Hepatitis C and Poliovirus. The most likely source is the uncontrolled movement of people and goods, which is not regulated in countries where these viruses are not eradicated. These include HIV, SARS, which has a 15% death rate, and Avian influenza which has spread widely in recent years all over the world.
