A case of measles has been confirmed in a Latah County, Idaho resident. This is the first confirmed case in Idaho since 2001. In addition to the Idaho case, there are ongoing measles outbreaks in Washington, New York, Pennsylvania, Maryland, Georgia, California and Michigan. Summ

Hepatitis A continues to be of concern in our region with eight cases being diagnosed among Ada and Elmore county residents this year, and an additional seven throughout the state. Providers should continue to test patients with clinically compatible signs and symptoms and vaccinate susceptible adults and children.

Since the first of the year, six hepatitis A cases have been reported among Ada and Elmore County residents. Typically, 1-2 cases are reported in an entire calendar year. All reported cases have been men between the ages of 30 and 60. Only one reported out-of-state travel during the most likely exposure period. No common risk factors for illness have been found.

As part of a voluntary water testing program, school officials recently detected elevated lead levels (>15 parts per billion (ppb)) in some drinking water samples at Fairmont Junior High. As Boise School District continues to test other schools, there may be additional public announcements about elevated water lead levels in fountains or faucets. Parents may have questions about the risk to their children’s health, or about the need for blood lead testing. As CDC case studies have demonstrated, exposure to a water source with elevated lead levels does not necessitate blood lead testing (CDC, 2004; 2010; 2012; 2016). Lead levels in Boise’s drinking water are not elevated so lead is typically from the fixture or plumbing components.

Plague was confirmed this week in an Elmore County child. The child was in Idaho and Oregon during the incubation period. A source has not been identified and the investigation is ongoing. No ground squirrel die-offs have been detected this year in Ada or Elmore County or in Oregon.

Central District Health (CDH) has identified six Shiga-Toxin Producing E. coli (STEC O157:H7) cases who are associated with a nation-wide cluster. Onset dates for CDH patients range from March 25 to March 30. Please continue to watch for new cases.

During the last three months, 12 pertussis cases have been reported among Ada County residents. This is twice the number compared to the same time period last year. Many of the cases are in teenagers and young adults (i.e. 13-20 years old), however 25% of the cases are older than 40.

Idaho Bureau of Laboratories (IBL) provides testing for emerging diseases when diagnostic testing is limited or nonexistent in the commercial sector. Zika virus testing was a recent example of this. Since commercial testing for Zika is now widely available in clinical reference laboratories, IBL is no longer accepting specimens for routine Zika testing. Specimens should be sent to the health care facility’s commercial laboratory.

In 2014, the United States saw an unexpected increase in the number of reports of children experiencing neurologic illness with presentations similar to acute flaccid paralysis (AFP). The syndrome was named acute flaccid myelitis (AFM) to better distinguish it from other forms of AFP.

Please consider Zika virus infection when evaluating symptomatic patients or pregnant women with recent travel to affected areas.
