The possible exposures happened when an infected Solano County resident was in the Sutter Medical Center neonatal unit in Sacramento in late March and was then in the Northbay Medical Center in Fairfield in early-to-mid April.
Dr. Michael Stacey is the Solano County Chief Medical Officer.
STACEY: "We have records of everybody that was in the NICU and we know when this person was in the NICU. And so, we are able to clearly define who was potentially exposed in the NICU setting and we've identified all of those infants."
Stacey say the families and babies identified as at-risk need to be tested. If any of them test positive…and he says the risk is low…then there is 6-to-9 months of treatment with medication.
Sacramento and Solano counties had about 110 cases of active tuberculosis last year.
