Tick and mosquito infections spreading rapidly, says CDC

The number of Americans affected by diseases from mosquito, tick, and flea bites has more than tripled from 2004 to 2016, with over 96,000 cases reported in 2016. Zika and Lyme disease were the most common. The rise in cases is attributed to global warming, which boosts insect populations, and increased travel, which spreads infections. The CDC highlights these factors as key contributors to the growing health concern.
