Nueva evidencia de riesgos de virus del comercio de vida silvestre

Un estudio muestra que las ratas vendidas en los mercados y restaurantes del sudeste asiático albergan múltiples coronavirus.

La proporción de positivos aumentó a medida que los animales vivos fueron trasladados de «campo a tenedor», lo que sugiere que estaban detectando virus en el proceso.

Las cepas detectadas son diferentes de Covid-19 y no se cree que sean peligrosas para la salud humana.

Pero los científicos han advertido durante mucho tiempo que el comercio de vida silvestre puede ser una incubadora de enfermedades.

La mezcla de múltiples coronavirus, y su aparente amplificación a lo largo de la cadena de suministro en los restaurantes, sugiere un «riesgo máximo para los consumidores finales», dijo un equipo de investigadores de Estados Unidos y Vietnam.

Esta no es la última pandemia.

La carrera por encontrar la fuente del coronavirus en la vida silvestre

Explotar la naturaleza ‘impulsa brotes de nuevas enfermedades’

Se cree que los orígenes de la pandemia actual se encuentran en el comercio de vida silvestre, con la enfermedad emergiendo en murciélagos y saltando a las personas a través de otra especie, aún no identificada.

Los nuevos hallazgos, considerados como preliminares, se refieren a ratas, pero pueden aplicarse a otras especies silvestres, como civetas y pangolines, que también se recolectan, transportan y confinan en grandes cantidades.

Se detectaron seis coronavirus conocidos en muestras tomadas en 70 sitios en Vietnam en 2013 y 2014. Se encontraron altas proporciones de muestras positivas en ratas de campo destinadas al consumo humano. La proporción de positivos aumentó significativamente a lo largo de la cadena de suministro:

Granjas – 6%

Comerciantes – 21%

Grandes mercados: 32%

Restaurantes – 56%.

Las tasas de detección en poblaciones de roedores en su hábitat «natural» están más cerca del 0-2%, dijeron los investigadores.

El estudio se realizó con expertos en salud animal en Vietnam, que está considerando prohibir el comercio y el consumo de vida silvestre. Aparece en la revista preimpresa bioRxiv antes de la revisión por pares.

Los expertos en conservación dicen que la pandemia de coronavirus es un momento decisivo para frenar el comercio mundial de vida silvestre. Advierten que los mercados húmedos pueden ser «bombas de tiempo» para las epidemias, que reúnen diferentes especies que pueden eliminar y propagar virus.
