How do viruses (h5n1) transmit from the animals to the humans?

How do viruses (h5n1) transmit from the animals to the humans?

Personal contact: Research is incomplete, but so far transmission to humans from animals (mostly birds) has been uncommon (happily) and mostly personal contact. Airborne transmission does not seem important at this time, but there is fear this could change if the virus mutates. If so, and if highly transmissible (i.e. infection by only a few virus particles), the world could see major epidemics. Fingers crossed! ...Read more

How are the herpes virus and herpangina distinguished from each other?

How are the herpes virus and herpangina distinguished from each other?

Several differences: While both are viruses, they are different classes and do different things. Herpangina is coxsackie virus which attack soft palate/throat and is self limiting within 10 days. Herpes initially can occur throught the entire mucose (primary herpetic gingivostomatitis) but recurrence usually is localized to the lips and peeioral skin. Likewise it is self limiting. ...Read more

Do different viruses ever attack each other? If you got sick from 2 viruses that infected the same kind of cells would they just ignore each other?

Do different viruses ever attack each other? If you got sick from 2 viruses that infected the same kind of cells would they just ignore each other?

Unlikely: Part of our modern viral treatments comes from recognizing that they can generate a protein called interferon, which blocks the competing virus.When you get a virus, it is as if every room(cell) in your hotel (body)was taken over by the virus, There is actually some interferon lingering after your virus fades, which allows you some time to recover. ...Read more
