Medidas de prevención de la transmisión de la influenza en trabajadores agrícolas desde un análisis de su patogénesis

“…Todo lo anterior buscando mejorar los sistemas de vigilancia para este sector económico, dado la Organización de las Nacionales Unidas para la Alimentación y la Agricultura FAO ha recomendado a países de la región aumentar la participación de este sector comercial en la vigilancia y vacunación (26). También dando claridad que asociado a lo anterior las medidas presentadas en el figura 1 se deben establecer en granjas producción porcícola y avícola tecnificadas, además de los pequeños propietarios de aves y cerdos de corral (27,28), dado el riesgo de propagación del virus aumenta con la presencia de viviendas cerca a los corrales de los animales, inadecuadas prácticas de segregación de animales muertos, contaminación de aguas por animales infectados, no uso de elementos de protección y falta de vacunación (29,30).…”

Costs associated with acute respiratory illness and select virus infections in hospitalized children, El Salvador and Panama, 2012–2013

“…While estimates are now available about the burden of ARI and the effectiveness of some prevention and treatment strategies in Latin America, 9,10 the economic costs of ARI remain largely unknown which precludes assessments of the cost effectiveness of existing and emerging respiratory virus prevention and treatment strategies. 4 To inform future analyses of the cost effectiveness of ARI interventions, we estimated the hospitalization costs from the societal perspective of all-cause ARI and ARI associated with common respiratory viral pathogens among children aged < 10 years participating in a clinical trial of empiric oseltamivir treatment in El Salvador and Panama.…”

Timing of respiratory syncytial virus and influenza epidemic activity in five regions of Argentina, 2007‐2016

“…Influenza vaccination starts as early as March in Buenos Aires, Argentina's capital and largest city, and continues throughout the influenza season. Influenza vaccines have been shown to provide moderate protection against influenza‐associated hospitalizations in young children and older adults . In Argentina, vaccine coverage among young children has reached 80% and about half of adults report getting vaccinated against influenza .…”

“…Influenza vaccines have been shown to provide moderate protection against influenza-associated hospitalizations in young children and older adults. 19 In Argentina, vaccine coverage among young children has reached 80% 20 and about half of adults report getting vaccinated against influenza. 21 The MOH also recommends the use of empiric oseltamivir among persons at high risk of influenza illness complications and among hospitalized persons suspected of having influenza throughout the season.…”

“…Similar to other countries,27 influenza activity in Argentina starts in the region with the country's capital and major air and maritime ports and, within 3 weeks, propagates to neighboring regions. Argentina vaccinates against influenza starting in March,18 and vaccines are offered throughout the influenza season 19. Influenza vaccine-induced immunity is thought to last through a season, but there is some evidence that protection wanes over time, especially for influenza A (H3N2) viruses 28.…”
