How many people are affected by Lyme disease? Here's what to know
Justin Timberlake recently shared his Lyme disease diagnosis on social media, calling the experience "relentlessly debilitating."
"If you've experienced this disease or know someone who has — then you're aware: living with this can be relentlessly debilitating, both mentally and physically," he wrote.
Timberlake shed light on a disease that impacts thousands of Americans every year. Over 89,000 cases of Lyme disease were reported to the Centers for Disease Control and Prevention by state health departments in 2023 – the most recent year of data available. According to the CDC, other estimates found that the number of those diagnosed and treated for the disease could be as much as 476,000 annually.
Globally, an estimated 14% of the world's population has been diagnosed with the disease, according to Project Lyme, an advocacy organization working to eradicate the epidemic of tick-borne diseases.
The CDC said Lyme is the most common disease transmitted through tick bites. Here's what to know about the tick-borne illness:

The blacklegged tick and Western blacklegged tick can spread Lyme disease, which can lead to a wide range of health problems.
In high-risk areas, an estimated 10% to 50% of blacklegged ticks carry the bacteria that cause Lyme disease.
These high-risk areas include:
Hallmark symptoms of Lyme disease in the acute stage include a 'bullseye' rash (erythema migrans), fever, chills, fatigue and muscle and joint aches.
Without treatment, Lyme disease can progress to include neurological, heart and joint problems.
