we just had dinner out and since I have been vomiting for weeks, I was very hungry and craved for eating something. but after finishing my meal, I realized that the restaurant is very unhygienic, they have no dishwasher and dishes are being washed by hand. :( I tried to vomit as if I could get rid of the microbes I may have taken but unfortunately I could not, ironically after vomiting endlessly when I did not want to. is my situation dangereous or am I exaggerating? can I contact hep. b or influenza ?
