Negative stool culture results not required for non-serotype Typhi Salmonella species. | Symptomatic contacts should be excluded until symptoms resolve. Stool cultures are not required for asymptomatic contacts. Antimicrobial therapy is not recommended for asymptomatic infection or uncomplicated diarrhea or for contacts. |
