One-step immunochromatographic test for the differential detection of Norovirus Genogroups I and II in human faeces. Noroviruses are a type of single-stranded, positive-sense RNA viruses belonging to the family Caliciviridae. They are highly contagious viruses whose main routes of transmission are: person-to-person contact and through contaminated food/water (in the U.S. is estimated that they account for 50% of gastrointestinal outbreaks by food poisoning). They often cause large outbreaks in closed communities in a variety of environments such as hospitals, nursing homes, schools, kindergarten, restaurants, cruises,… where, once the virus has been introduced, the infection spreads very quickly.

One-step immunochromatographic test for the detection of Rotavirus in stool samples. Rotaviruses are one of the main causes of acute gastroenteritis. Gastroenteritis from enteric viruses can be mortal in risk populations such as children, the elderly or immunosuppressed individuals.With an incubation period of 1-3 days, infection is via the fecal-oral route. Characteristic symptoms are vomiting, watery diarrhea at 3-8 days, fever and abdominal pain. Immunization following the initial infection is incomplete, although later infections tend to be less severe than the first.

One-step immunochromatographic test for the simultaneous detection of Rotavirus and Adenovirus in feces. Rotaviruses are one of the main causes of acute gastroenteritis, particularly in children under two years of age. Transmission occurs through the fecal-oral route; the incubation period is between 1 and 3 days. Adenoviruses are the second leading cause of viral gastroenteritis in children (10-15%); they can also cause respiratory diseases and depending on the serotype, diarrhea, conjunctivitis, cystitis, and others. The main clinical symptom of gastroenteritis caused byadenovirusis diarrhea, for 9 to 12 days, also occurring with fever and vomiting.
