> Rotavirus outbreak in Chiapas: alert
> According to state authorities, the Secretariat of Health in Chiapas
> has declared an alert as a result of an outbreak of rotavirus
> infection and deployed multidisciplinary teams to the communities
> where cases have been confirmed.
> The head of Sanitary Jurisdiction VII, Andres Gerardo Espinosa, said
> in an interview that the number of cases of acute diarrheal disease
> in 2010 had increased by 30 percent compared with the corresponding
> period last year . Cases have been reported in 16
> municipalities in the regions of Costa, Sierra, and Frontera Sur,
> which comprise that jurisdiction.
> "We are facing a rather severe outbreak of acute diarrheal disease
> that we believe is the result of a rotavirus infection for which
> unfortunately there is no specific treatment," he said and added that
> so far the [samples] sent to the laboratories of the National
> Institute of Public Health have confirmed 15 cases of rotavirus
> infection in the jurisdiction, most of them from the municipalities
> of Tapachula and Huixtla, with no deaths reported. "Rotavirus
> infection causes severe diarrhea that may lead to dehydration and
> even death," Espinosa said.
> He reported that the state health sector is were working to implement
> a series of strategies to combat the disease. Starting on Mon 8 Feb
> 2010, sampling of food and water including sewage, drinking, bottled,
> and river waters has been initiated to detect rotavirus and bacteria
> that may be affecting the inhabitants of the region.
> Espinosa explained that currently there is a rotavirus vaccine that
> is only administered to children under one year old, but that "the
> disease affects the entire population." For this reason he called on
> parents to have their newborns vaccinated and urged the rest of the
> population to take extreme precautions.

> [Rotaviruses are 70 nm icosahedral, non-enveloped, double-stranded
> RNA viruses that belong to the family _Reoviridae_. The virus is
> characterized by its 3-layer capsid, an outer and an inner capsid and
> an internal shell that surrounds the 11-segment double-stranded RNA genome.
> Rotavirus is currently by far the most common cause of severe
> diarrhoea in infants and young children worldwide and of diarrhoeal
> deaths in developing countries with a distinct winter seasonality in
> temperate climates and year-round exposure in tropical countries.
> Virtually all children are infected by the time they reach 2 to 3
> years of age. Most symptomatic episodes occur between 3 months and 2
> years of age with a peak incidence between 7 and 15 months. Symptoms
> include watery diarrhoea, nausea, vomiting, abdominal pain, and
> dehydration. Outbreaks of rotavirus gastroenteritis in day-care
> centers and hospitals can spread rapidly among non-immune children,
> presumably through person-to-person contact, airborne droplets, or
> contact with contaminated toys. Children from low socioeconomic
> background and low birth weight infants have an increased risk for
> Rotavirus infection can also occur in adults, especially in
> institutionalized or hospitalized elderly patients. Both symptomatic
> and asymptomatic patients shed rotavirus in their stools for 7-10
> days, but shedding can last for several weeks. The virus is highly
> resistant in the environment and can survive for months in stools at
> room temperature.
> Three oral RV vaccines are currently licensed, a human monovalent
> live attenuated rotavirus strain, RotarixTM, a pentavalent live
> bovine-human reassortant vaccine, RotaTeqTM, and a lamb-derived
> monovalent live attenuated strain, LLR, which is only being used in China.
> Concerns remain regarding the potential effectiveness of any oral
> live vaccine in view of prevalence of competing intestinal flora in
> children, occurrence of mixed infections, high levels of maternally
> transmitted antibodies and micronutrient malnutrition. More detailed
> information on rotavirus disease and rotavirus vaccines can be found
