Sometimes, we believe that just because we weren’t aware of something previously, it must be new. Many people feel that way about Lyme disease.
They believe that because the tick-borne disease has been well-publicized in the last few decades, that must be when it started. Unfortunately, that’s not true.
Unlike the SARS virus and various flu viruses that mutate and expand their ability to infect people, Lyme disease is not caused by a virus but a bacterium that hasn’t changed much in the last 60,000 years.
