Kerala has been put on alert after at least 13 cases of norovirus have been recorded in Wayanad district.
The infection was reported in some 13 students of a veterinary college in Pookode near Vythiri in Wayanad district two weeks ago.
As State health minister Veena George asked people to be vigilant, here’s a look at what the virus is, its symptoms and what can be done to treat it.

Symptoms caused by norovirus typically include sudden onset nausea, projectile vomiting, diarrhoea and fever but can also include abdominal pain and aching limbs. Norovirus can also lead to dehydration, especially in young children, older adults and people with weakened immunity.

Three hepatitis A deaths are linked to the Famous Anthony’s outbreak in Roanoke, Virginia, with at least 49 illnesses and 31 hospitalizations, according to news reports. Roanoke City and Alleghany Health Districts officials did not release any more information about these patients.

This afternoon, the Roanoke City and Alleghany Health Districts (RCAHD) announced that they learned that a third adult who was hospitalized with complications has died from hepatitis A. The RCAHD will disclose no further information about the individual to protect privacy and out of respect for the family.
“It is always with extreme sadness that we report the death of an individual,” said RCAHD health director, Cynthia Morrow, MD, MPH. “This heartbreaking loss of life illustrates how serious this outbreak is. Unfortunately, in this situation, we have seen many individuals experiencing severe disease, and in some cases, their symptoms have continued to progress over weeks.”
Hepatitis A is a preventable disease. RCAHD urges everyone to consistently practice good hand washing and to consider getting vaccinated, especially if they fall into a high-risk population.
At this time, RCAHD staff have identified a total of 49 confirmed primary cases, including 31 hospitalizations. A small number of cases are still under investigation. No new cases have been reported to RCAHD this week.

Presence of norovirus GII in IV range salads from the Netherlands and Italy in Italy
The Famous Anthony’s hepatitis A outbreak has now sickened 50 people and hospitalized 31 as of October 26, 2021, according to news reports. A sick employee worked at that restaurant in mid to late August 2021. The Roanoke City and Alleghany Health Districts reported the increase in cases. This is an increase of 13 patients since the last update two weeks ago.
One of the problems with this viral infection is that people are infectious up to two weeks before they even know they are sick. The virus is very contagious and is easily passed from person-to-person, through contaminated food, and through contact with contaminated surfaces.

Norovirus in chilled clams from Italy in Spain
The patient count in a hepatitis A outbreak linked to Virginia restaurants continues to grow, with 44 people now confirmed as infected. One of the patients has required a liver transplant and one has died.
The cousin of the transplant patient reports the operation took place this past weekend. The outbreak patient’s husband and daughter were also infected, according to the cousin.

Norovirus (NoV) is the main non-bacterial pathogen causing outbreaks of gastroenteritis and is considered to be the leading cause of foodborne illness. This study aims to determine whether lettuce-encapsulated bacteria can express histo-blood group antigen (HBGA)–like substances to bind to NoV and, if so, to explore its role in protecting NoV from disinfection practices. Fifteen bacterial strains (HBGA-SEBs) were isolated from the lettuce microbiome and studied as they were proved to have the ability to express HBGA-like substances through indirect ELISA detection. By using attachment assay, HBGA-SEBs showed great abilities in carrying NoVs regarding the evaluation of binding capacity, especially for the top four strains from genera Wautersiella, Sphingobacterium, and Brachybacterium, which could absorb more than 60% of free-flowing NoVs. Meanwhile, the direct viral–bacterial binding between HBGA-like substance-expressing bacteria (HBGA-SEB) and NoVs was observed by TEM. Subsequently, results of simulated environmental experiments showed that the binding of NoVs with HBGA-SEBs did have detrimental effects on NoV reduction, which were evident in short-time high-temperature treatment (90°C) and UV exposure. Finally, by considering the relative abundance of homologous microorganisms of HBGA-SEBs in the lettuce microbiome (ca. 36.49%) and the reduction of NoVs in the simulated environments, we suggested putting extra attention on the daily disinfection of foodborne-pathogen carriers to overcome the detrimental effects of direct viral–bacterial interactions on the reduction of NoVs.
