A “bird of the house” exposed to industrial light during the night is more likely to carry the West Nile virus for longer than those who spend their nights in the dark, according to a new study.
According to the “phys”, the study, published in the journal Proceedings of the Royal Society, indicates that birds of infected houses that live in conditions of light pollution remain infectious West Nile virus for two days longer than those who do not, thus enhancing the efficiency of their host, To generate infection in hostesses or other carriers.
These are the first results indicating that light pollution can affect the spread of zoonosis diseases. Many hosts use signals to coordinate daily and seasonal rhythms. Disruption of these rhythms due to exposure to light at night may affect immune responses and generate the effects that occur.
The researchers studied 45 birds at home, showed half the artificial light at night, and after 7 to 25 days of captivity, the team exposed birds to the virus and took blood samples after exposure. The researchers found that all birds were infected within 2-4 days, , Birds exposed to light at night kept the virus longer.
While the West Nile virus is a virus transmitted arthropods origin animals transmitted by mosquitoes belonging to the genus of the yellow virus within the class virus yellowing.
