Los Angeles mosquito surge accompanies reported West Nile decade high
The Guardian links heat and humidity to a particularly severe mosquito year, but its excerpt provides no disease figures.
The Guardian reports that Los Angeles is experiencing one of its worst mosquito years in recent history. It attributes the conditions to heat and humidity and describes West Nile virus as being at a decade high.
What holds up
- ✓The supplied Guardian item explicitly reports unusually severe mosquito conditions in Los Angeles.
- ✓The same item reports a decade high for West Nile virus, although no underlying surveillance figures are included.
What doesn't yet
- ?The excerpt does not specify whether the West Nile comparison concerns human cases, infected mosquitoes or another measure, or define its geographical scope.
- ?The severity ranking and attribution to heat and humidity are not supported by methods or comparative data in the supplied text.
Ask before you share
- →What measure and geographical area underpin the reported West Nile decade high?
- →Do local surveillance records support the mosquito trend and the proposed weather link?
