2023-03-15. Schizophrenia pinpointed as a key factor in heat deaths. [https://www.science.org/content/article/schizophrenia-pinpointed-key-factor-heat-deaths] By Warren Cornwall, Science. Excerpt: ...more than 600 people died from the heat in British Columbia, as temperatures topped 40°C for days, shattering records in a region better known for temperatures usually half as high. Now, new research has zeroed in on one of the hardest hit groups: people with schizophrenia. Epidemiologists combing through provincial health records found that, overall, those with mental health conditions seemed to have an elevated risk of a heat-related death. That was most severe for people with schizophrenia—a 200% increase compared with typical summers. ...schizophrenia can affect the brain’s hypothalamus, which helps regulate temperature through sweating and shivering. Some antipsychotic medications can raise body temperature, which can have deadly effects when coupled with extreme heat. The disease affects people’s ability to make reasoned decisions or sense when they are ill. People with schizophrenia tend to have other conditions tied to heat-related illness, such as diabetes. Finally, schizophrenia is associated with isolation and homelessness, which puts people at risk when temperatures rise....

Excerpt: The appearance of a “tropical” mosquito-borne illness in southeastern Australia has unsettled researchers. ...McCann was the fourth patient in as many weeks admitted to Albury with encephalitis. Like McCann, the three others had turned up feverish and confused. ...among the possible causes were mosquito-borne viruses, in particular two encephalitis-causing viruses endemic to Australia: Kunjin, a strain of West Nile virus, and Murray Valley encephalitis virus (MVEV), named for the river valley where McCann has swum, water skied, fished, and boated since he was a boy. ...As with other weather events, the record-breaking wetness of the 2021–22 season can’t be attributed with certainty to climate change. But as the globe warms, the atmosphere holds more water, enabling more intense rainfall and flooding; daily rainfall associated with th
