### input:
hi doctor,i am 21 years old,11 months back i had sexual contact with a stranger(protection was taken ) and wondered of many problems.6 months after i was tested for all types of std tests(consulted doctor,he recommended these tests) like hiv,syphillis,hep b,herpes,but all results are negative,he concluded that i am free from stds .I  asked the doctor whether i needed to be tested again after 3 months and he replied it is not necessary to test again because all these tests including hiv surely will show  positive results after 3 months from iitial contact and thus he concluded i am free from all stds.but yesterday i got tested with hepatitis A,B,C and my hepatitisA result was positive and remaining botChatDoctore negative.Now what i wonder is do we get false-positive(hepA) result if we have any of the stds(including hiv).So i really want an answer regarding this issue.I know that there is no cure for HepA,but any possible to protect it.reasons why i want to test for all types of hepatitis:1)frequent head aches(during nights)2)i like to smoke,but some times my body dosent accept me to smoke(i sometimes feel nausea while smoking)3)all this 9 months of period i got diahrrea 5-8 times(loose motions).4)i observed some rashes on legs,scalp,even on genitals.Looking for a positive and geniune reply.thankyou.

### output:

Hepatitis A is not a sexually transmitted infection. It is more because of consuming contaminated food or water. You can get a false positive result in case of other infections even the non-std kind. I am concerned that you are in a state of worry and that makes you attribute everything to hepatitis or STDs. That is not the case. Diarrhea, headaches, rashes happen to normal people too. Just don't get so stressed. That itself will cause diarrhea and headaches. If you want to prevent it, both Hepatitis A and Hepatitis B have vaccinations available. Thanking you for your query.
