Lyme Disease Outbreaks May 2023

Lyme disease (Lyme borreliosis) is a bacterial disease transmitted to humans through the bite of infected ticks. It is a tickborne disease common in Europe and the United States, says the World Health Organization (WHO). The risk of contracting a tickborne infection is determined by the number of ticks in an area, the proportion of those carrying the disease, and human behavior, such as walking in tick-infested fields.

Lyme Disease Outbreaks in the U.S.

During the past 15 years, Lyme disease diagnoses have increased dramatically in the U.S., increasing over 300% in rural areas and 65% in urban areas, according to data released by FAIR Health in 2022. The top states in 2021 were New Jersey, Vermont, Maine, Rhode Island, and Connecticut.

As of January 2023, the U.S. Centers for Disease Control and Prevention (CDC) published a Lyme disease case map for the U.S. Each year, state and local health departments report cases of Lyme disease to the CDC through a passive reporting system, the Nationally Notifiable Diseases Surveillance System (NNDSS). A recent estimate based on insurance records suggests that approximately 476,000 Americans are diagnosed and treated yearly for Lyme disease.

In the U.K., the Health Security Agency says Lyme disease-carrying ticks are most active in the spring and summer months when the weather warms up but can be found all year round. Around 3,000 cases of Lyme disease are estimated to be diagnosed in England annually.
