its easier to catch hepatitis then hiv. hiv dies pretty quickly outside the body. hepatitis can remain active in dry blood on a surface for days. ie bleach the blood stain on the sidewalk. other stds make it easier to catch hiv because they weaken the immune system. there are now different strains of hiv and the current meds do not work on all of the forms. same for hepatitis so many its hard to keep track of them. there are people that are strictly carriers of hiv and hepatitis strains that never develop the diseases themselves. syhillis can be treated in stage 1 stage 3 no treatment will work. there is a new strain of chlamydia that is becoming a real problem. most people dont know they have this std but the newest version is nasty.
