Norovirus Published Feb. 1, 2010 By Staff Sgt. Erika Payne 20th Aerospace Medicine Squadron SHAW AIR FORCE BASE, S.C. -- While the H1N1 virus is no longer on the forefront of the media, a new virus has emerged that is causing an increase in the number of gastrointestinal illnesses in the state of South Carolina. Since Jan. 1, the South Carolina Department of Health and Environmental Control has investigated 13 outbreaks of gastrointestinal illness that are either laboratory-confirmed Norovirus or have epidemiologic features similar to Norovirus. The 20th Medical Group has also noticed an increase in the number of visits due to gastrointestinal illness. There are no confirmed cases of Norovirus at Shaw Air Force Base. Norovirus causes a sudden onset of gastroenteritis, or inflammation of the intestinal tract. Symptoms typically include nausea, vomiting, diarrhea, abdominal cramping and in some cases, a low-grade fever. The symptoms usually last about one to two days. However, young children, the elderly and those who are immunocompromised may experience severe symptoms which can lead to dehydration. There are ways to prevent acquiring or transmitting the virus to others. Since Norovirus is found in the stool or vomit of an infected person, hand washing is a key preventive measure. Wash your hands frequently and thoroughly especially after using the bathroom, changing diapers and before handling food. Carrying hand sanitizer is also a great option, but remember that hand sanitizers will not be effective if your hands are visibly soiled. There is currently no antiviral or antibiotic treatment for Norovirus infection. Active Duty members experiencing the above symptoms should notify their supervisor. In accordance with Air Force Instruction 41-210, Patient Administration Functions, unit commanders and supervisors have the authority to grant up to 24-hours sick status if a members illness/injury does not require intervention at a military treatment facility. If you are ill with Norovirus-like symptoms you should drink plenty of fluids to reduce the chances of becoming dehydrated. Also, frequently touched surfaces such as doorknobs, desktops and telephones should be disinfected on a regular basis with a bleach-based cleaner. Wash all clothing or linens that may be contaminated using hot water and soap. If symptoms have not subsided after 24 hours or have gotten worse, contact the clinic at 895-CARE (895-2273) to schedule an appointment.
