MALMSTROM AIR FORCE BASE, Mont. --  There has been an increase in the number of cases of "stomach flu"-like illnesses in Montana in recent weeks. Often the culprit behind these ailments is a group of pathogens collectively called Norovirus. While upticks in this type of illness are common in late summer and early fall, good sanitation practices can curb these elevations and lead to a healthier, more comfortable season.

This virus is easily transmitted and can survive long periods of time in the environment if not disinfected. One way in which Norovirus is spread is by eating food and/or drinking liquids contaminated with the virus. Another way Norovirus is passed on is by touching surfaces or objects contaminated with the virus and eating, drinking or touching your mouth without washing your hands. Also, having close or direct contact with someone who is infected is a prime way for Norovirus to be transmitted.

Symptoms may begin suddenly, but the illness is usually brief - only lasting one to two days. Some of these symptoms include: nausea, vomiting, diarrhea, stomach cramping, low fever, chills and headaches. Those who contract the virus are contagious from the start of symptoms to about 3 days - up to 2 weeks - after symptoms resolve. The main concern with this virus is the high risk of dehydration due to the profuse vomiting and diarrhea. Therefore it is crucial to drink enough liquids to prevent this. If proper hydration is not achieved medical attention may become necessary. Currently there is no vaccine to prevent Norovirus infection.

The best way to avoid becoming infected with Norovirus is by using basic sanitary practices. There are several key practices that will help keep you healthy:

· Always wash your hands after using the restroom or changing diapers and before preparing or eating foods - especially fruits and vegetables.

· Clean and disinfect contaminated surfaces using a bleach-based household cleaner immediately after an episode of illness.

· Remove and wash clothing or linens that may be contaminated.

· Flush or discard any vomit or stool in the toilet, and make sure that bathrooms are kept clean.

Basic sanitary practices are the key to good health. For more information about Norovirus, call the Malmstrom Public Health Office at 731-4405.
