People who visited a south Lansing gas station during a two hour period overnight from April 11 to 12 may have been exposed to measles, according to the Michigan Department of Health and Human Services.

The Speedway at 6041 S. Pennsylvania Ave. is listed as an exposure site in the department's latest release about the ongoing measles outbreak in Michigan.

The measles virus stays active in the air for about two hours after an infected person sneezes, coughs or breathes.

Since the outbreak started in mid March, 42 Michigan residents have been diagnosed with measles.

The infected individuals range from 8 months to 63 years old.  The most recent cases involve two adults, one from Oakland County and one from Detroit.  One of those people traveled in Ingham and Kent counties while infectious.
