Clinical differences between respiratory viral and bacterial mono‐ and dual pathogen detected among Singapore military servicemen with febrile respiratory illness

“…Among dual infections, virus–virus pairs constitute only 3.0% of the entire data set, within the lower end of range of viral co-infection studies in ambulatory settings (1.73–15.3%). 6 , 8 , 9 This may be due to local interactions between immune and microbial mechanisms preventing the occurrence of co-existing viral respiratory pathogens. Such negative correlations have been previously described, 27 including the replacement of one virus with another when the former is removed from the general population through vaccinations.…”

“…Among dual infections, virus–virus pairs constitute only 3.0% of the entire data set, within the lower end of range of viral co‐infection studies in ambulatory settings (1.73–15.3%) . This may be due to local interactions between immune and microbial mechanisms preventing the occurrence of co‐existing viral respiratory pathogens.…”

“…For instance, one study showed that 15.3% of ambulatory patients with influenza‐like illness had two viruses detected, and another found that in 28.2% of children with community‐acquired pneumonia, the illness was due to mixed viral–bacterial infections . Others also previously described respiratory viral and bacterial co‐infections in various settings, although most focus on specific pathogen combinations, especially of the synergism between influenza and Streptococcus pneumoniae ( S. pneumoniae ) …”

Detección de gripe y de otros virus respiratorios durante un periodo pandémico y postpandémico de nueva variante de gripe

“…Permanece como incógnita la descripción de cuál de los virus que Éstas fueron más frecuentes en niños que en adolescentes y adultos.Nuestros resultados muestran que la descripción epidemiológica de las coinfecciones puede aportar luz al conocimiento, en el sentido mencionado en el párrafo anterior, ya que en invierno su presencia ha sido mayoritaria y ha doblado en porcentaje a las infecciones simples. Hecho escasamente documentado en la literatura144,[145][146][147] que concuerda con las razones expuestas además de un mayor predominio de algunos virus de reciente desarrollo diagnóstico (Bocavirus, metapneumo, corona, etc).Desde el punto de vista práctico; de nuestra experiencia se desprende la necesidad de incorporar tanto a las redes de vigilancia como a la práctica clínica la detección de otros virus respiratorios. Todas las redes que conocemos en nuestro país estarían en condiciones de ampliar su oferta diagnóstica y de este modo responder tanto al interrogante de la verdadera circulación de los virus como al esclarecimiento de su significado meramente patogénico.…”
