Or norwalk, noroviruses are a group of viruses that cause viral gastroenteritis, also known as acute non-bacterial gastroenteritis or food poisoning. Symptoms include nausea, vomiting, abdominal pain, diarrhea, low-grade fever, chills, anorexia, headache and fatigue. Noroviruses are transmitted by fecal-oral contamination through water and food vehicles, and by person-to-person transmission. Pollution of shellfish waters and poor personal hygiene are common contributors. Infected persons contaminate all foods other than shellfish. Noroviruses are not a notifiabledisease in the United States and therefore estimates are unreliable. However, due to the mildness of some viral gastroenteritis infections,noroviruses are grossly under-detected and underreported. Noroviruses are responsible for approximately 1/3 of all viral gastroenteritis in people over the age of 2. Formerly call Norwalk virus.
- Novel H1N1
A new influenza virus spreading person-to-person worldwide, first documented in Mexico in March 2009 and in the United States in April 2009. The World Health Organization (WHO) labeled it a pandemic in June 2009. Originally dubbed "swine flu," this new virus is actually very different than the flu viruses that are common in pigs. H1N1 is a combination of bird, swine and human viruses that is spread much like the seasonal flu; through coughing and sneezing by people with the virus. Touching a surface already contaminated with flu virus particles and then touching one's mouth, nose or eyes also spreads the virus. The chances of catching H1N1 this way can be lessened by performing proper and frequent hand washing and surface cleaning.
Common H1N1 symptoms include cough, fever, sore throat, runny or stuffy nose, headache, body aches and fatigue, and less often diarrhea and vomiting. Symptoms can be mild to severe, with virus shedding occurring 1 day prior to the onset of symptoms until 5 to 7 days after. Although the majority of sufferers recover from the flu within a week without hospitalization or additional treatment beyond oral anti-viral medication, individuals with weak immune systems are at risk of serious complications and even death. A vaccine is currently available to high-risk individuals including children, pregnant women and those with chronic illnesses. (see Swine Flu)
