Parts of Thailand were left unrecognizable at the end of last year, after the country experienced its worst floods in 50 years. The tops of vehicles at a Honda factory in Ayutthaya province (pictured) peeked out from under receding water. The flooding, brought on by an unusually heavy monsoon season, immersed about one third of Thailand’s provinces, displacing thousands and killing more than 650 people. Stagnant waters brought fears of mosquitoes carrying malaria and dengue fever.
