Residents in southeastern Minnesota are being warned about a handful of recent cases of bacterial meningitis in and near Houston County that could not have been prevented by a vaccine.
There has been "a cluster" of cases in the past five weeks, with the fourth one being investigated this week, according to Houston County's Public Health Department.
None of the cases was serious, and everyone has recovered, said Doug Schultz, a spokesman for the Minnesota Department of Health. Two patients became ill in February, and the most recent case was reported March 28.
Schultz said the department is unsure if the cases are connected, but he has advised local clinics and schools to watch for additional cases.
Bacterial meningitis is spread through close contact, such as coughing, sneezing or kissing. It can be fatal or debilitating in a matter of days.
Each year, about 3,000 Americans contract meningococcal disease -- a range of brain, spinal and blood infections, which includes meningitis. About 300 die each year from such infections.
It often strikes suddenly, causing a high fever, severe headaches and nausea. About 15 percent of meningococcal disease survivors suffer serious long-term effects, such as brain damage, amputations and hearing loss.
The state has confirmed the first three of the latest cases; confirmation of the fourth is pending, the county said. Ages of the people involved range from 16 to 37.
The meningitis vaccine does not protect against the specific bacteria that has been identified in these cases, the county said.
Therefore, the county is reminding its residents that the most effective prevention for the spread of meningitis and other infections is "conscientious and consistent hand washing."
It also added that it's important for people not to share "lip gloss, cigarettes, and eating or drinking utensils (pop cans/bottles, water bottles, straws, cups, etc.)."
