      I’m sorry if this is in the incorrect section but my question seems to fit into many sub-forums. BTW this is not a homework question, I was just curious.

      I was thinking about blood-borne viruses, and apart from their vector being blood do they share any characteristics on how they infect the cells? Google didn’t really shed too much information on this question. I found out that HIV infects the the cell and reverse transcribes the viral RNA into viral double stranded DNA. Hepatitis does the same but it is not a retro-virus. Apart from Hep and HIV, I couldn’t any list of blood-borne viruses.

      What I’m really after is a question I saw on another forum that didn’t really get too many quality responses.

      The question was : Design a means to prevent the spread of ALAS (fictional blood-borne virus) that is susceptible to air, heat, cold, acid and alkali.

      ALAS is from the short story "The Giving Plague" by David Brin. (http://www.davidbrin.com/givingplague1.html) I read the short and found it an incredible read. Essentially, ALAS is a blood-borne virus that compels the host to donate blood and that is how it passes from one host to another.If you ever have a moment, read the story, it is very enjoyable.

      That’s why I was wondering if all blood-borne viruses share some of the same characteristics.
      To answer the question I thought synthesized short interfering RNA bound to a molecule that would transport it to the nucleus could target the viral genes in the DNA to silence the genes and prevent them from being expressed. I assume if you are pretreated with siRNA specific for the viral genes then the virus would never be expressed. I do not know if the susceptibility to air, heat, cold, acid, or alkali would make finding a cure any easier.

      Am I way off on any of this? Does anyone have any ideas or suggestion for any reading that I could do on blood-borne viruses and how to prevent viruses from spreading. I could not find much on google. Its fun to play virologist.

      I wouldn’t have thought a susceptibility to air, heat, cold, acid, or alkali would make it any easier to cure because most pathogens are to an extent. Once it is in the blood I would not have thought you could use those factors against the virus without killing the patient.

      Your idea of using siRNA as a treatment sounds good though, what molecule would you use to transport to the nucleus?

      The most common examples are HIV, hepatitis B, hepatitis C and viral haemorrhagic fevers. Diseases that are not usually transmitted directly by blood contact, but rather by insect or other vector, are more usefully classified as vector-borne disease, even though the causative agent can be found in blood. Vector-borne diseases include West Nile virus and malaria.
