 [ Symptoms ] how can i get my 5 month old to eat his cereal [ Disease ] herpes simplex virus 2 hsv2 igm refers to current infection or outbreak so this would be postive if you recently have had or currently have a herpetic outbreak whereas hsv2 igg refers to a previous infection which means that you have been infected with the herpes virus and are therefore able to transmit the virus to someone else once you have the virus like all viruses you will have it forever essentially a positive igg and negative igm means you have the virus but not a current or recent outbreak if you have frequent outbreaks or if your partner tests negative for herpes it is very important that you start suppresive antiviral therapy to prevent outbreaks and to decrease the risk of transmitting the virus realize that even if you are on suppresive medication you can still pass the virus on to your partner so using a condom is also very important
