Understanding how live pigs are traded between villages and backyard farmers can help health agencies better understand how devastating swine diseases spread, according to a study published recently in the journal PLOS ONE.

Foreclosed McMansions = Mosquito heaven

Home mortgage delinquencies in Bakersfield, Calif. increased 300 percent in 2007, while cases of West Nile virus almost tripled in the same year, according to a study by UC Davis entomologist William Reisen and colleagues.

The link? Neglected swimming pools and jacuzzis turning green and providing a perfect habitat for mosquitoes. More alarmingly, many of the pools were colonized Culex tarsalis, a species of mosquito usually found in more rural areas, which is better at transmitting West Nile virus than the mosquitoes it has replaced.

This aerial photo from the paper shows green and neglected pools in Bakersfield.  The paper is published in the current edition of the journal Emerging Infectious Diseases.
