There are three main viruses that have been studied and confirmed as the agents responsible for<unk> , including enterovirus 70, coxsackievirus A24 variant (CA24v) and adenovirus 11.<unk>  can only exist in a human host and is transmitted through human contact with an infected individual or object, such as a towel used by an infected person. It is also easily communicable through fecal-oral pathways, thus allowing for its abundance in areas of the world with low levels of hygiene. Within one to two days of infection, symptoms will begin to become apparent. Enterovirus 70 Enterovirus 70 is a member of the genus of viruses called Enterovirus and family of the viruses Picornaviridae. Usually very small (about 30 nm in diameter), it is non-enveloped (meaning it only has a nucleic acid core and protein capsid) and has a single-stranded positive-sense RNA genome; the protein capsid the virus itself is surrounded by is icosahedral. It is known as one of the newer enteroviruses within this category. It spreads easily from one person’s eyes to another’s through contact with infected objects, like fingers, or through the eye secretion itself. Enterovirus 70 infrequently causes polio-like permanent paralysis. Coxsackievirus A24 variant The Coxsackievirus is another member of the genus of viruses called Enterovirus and family of the viruses Picornaviridae. Its isolation host is human. It is an antigenic variant of the Coxsackievirus A24. It was studied independently for the first time in Singapore in 1970. Adenovirus 11 Adenoviruses are a medium-sized variant that are nonenveloped, like Enterovirus 70. They have a double-stranded linear DNA genome. There are 57 variants of this virus, that each cause 5-10% of upper respiratory infections in humans. These viruses are some of the largest nonenveloped viruses in existence, and because of this, they can pass through the endosome without any necessary envelope fusion.
