5 min. is too short: On the West Coast, the western black-legged tick can bite humans, and can cause Lyme disease, after feeding for 24-48 hours. A later blood test can help tell if a person got infected. The doctor may treat with antibiotics if the lab finds "Lyme bacteria", if the bite site has a bull's-eye rash, or if there are other worries, such as a lot of irritation and maybe a skin infection at the bite site.
