Document Summary
Inapparent infection: steps of viral pathogenesis, human viral entry points, spread, viral transmission. Focus on hosts for virus replication: genomes establish themselves in host ensuring long term survival. If viruses make it past all these walls = deadly or extensive long term damage. Why: very salty chemical property, 90% of the skin is dead cells, this is comparable to the leaf experiment, viruses need live hosts to utilize the mechanics to replicate. Viruses are constantly being introduced in various parts of the world. Recap: lecture 1: viruses are everywhere and sometimes can even cause disease. Yet sometimes we don"t know since there are no apparent symptoms. The concept of inapparent infection: no symptoms yet immune system has been activated, even in an inapparent infection: replication and transmission can still occur. Flaviridae: causes the disease west nile virus: +rna ready to go rna, with envelope, nucleocapsid on the inside since it is directly interacting with the genome, spread by mosquitoes.
