Summer isn't just about fun and laughter! Warm weather can cause a variety of specific diseases to rise during this period. Valley Fever, West Nile Lyme Disease, and food poisoning are just some of them. An interesting trend can be observed in crime rates too. Though they don’t increase by much, the types change a bit. Thieves are more likely to steal a bike in the summer, whereas in winter, their goal is likely to get gifts.
