Introduction Since its emergence in late 2019, the SARS-CoV-2 virus — the cause of COVID-19 — has continued to evolve. Each new variant brings changes in how the virus spreads, how sick it makes people, and how well vaccines or treatments work. While the worst phases of the pandemic have passed, COVID-19 remains a global health concern, particularly as new variants emerge. As of mid to late 2025, the global health community is closely monitoring several current COVID-19 variants that differ from previous strains. This article explores the latest variants, how they are spreading, what symptoms they cause, and their…

Introduction Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common tick-borne illness in the United States, Europe, and parts of Asia. Transmitted primarily by the blacklegged tick (also called the deer tick), the risk of infection is heavily influenced by geography. Understanding where Lyme disease is most prevalent can help individuals, families, and pet owners take proactive steps to protect themselves. This article explores the global and regional spread of Lyme disease, with a special focus on high-risk areas, reasons for its expansion, and practical prevention strategies. What Determines the Geographic Spread of Lyme Disease? The spread…

Introduction Lyme disease isn’t just a concern for humans—dogs are also vulnerable to this potentially serious tick-borne illness. Caused by the bacterium Borrelia burgdorferi and transmitted primarily by the blacklegged tick (deer tick), Lyme disease can lead to long-term health complications in dogs if left untreated. This article will help dog owners understand how Lyme disease affects their pets, what symptoms to look for, how to prevent infection, and when to seek veterinary care. What Causes Lyme Disease in Dogs? Lyme disease is caused by the spiral-shaped bacterium Borrelia burgdorferi. It’s transmitted when an infected tick attaches and feeds on…

Introduction Lyme disease, caused by the bacterium Borrelia burgdorferi and transmitted by ticks, is the most common vector-borne illness in North America and Europe. While many people recover fully after appropriate antibiotic treatment, a subset continues to experience lingering symptoms. This has led to the controversial and widely debated concept of Chronic Lyme Disease (CLD) or Post-Treatment Lyme Disease Syndrome (PTLDS). This article breaks down what Chronic Lyme Disease is, why it’s controversial, the difference between PTLDS and CLD, perspectives from both sides of the debate, and what patients should know about treatment and support. What Is Lyme Disease? (Quick…

Introduction Most people associate tick bites with Lyme disease. But ticks can carry and transmit multiple pathogens, sometimes at the same time, leading to what’s known as tick-borne co-infections. These infections can complicate diagnosis, delay treatment, and increase the severity of symptoms. In this article, we’ll explore the most common tick-borne co-infections, how they’re transmitted, symptoms to watch for, testing, treatment options, and how to protect yourself. What Are Tick-Borne Co-Infections? A co-infection occurs when a tick transmits more than one disease-causing pathogen in a single bite. The most common tick species responsible for co-infections in the U.S. is the…

Introduction Lyme disease, caused by the Borrelia burgdorferi bacterium and spread through tick bites, is usually treatable with antibiotics. However, for some individuals, symptoms persist even after completing treatment. This condition is known as Post-Treatment Lyme Disease Syndrome (PTLDS). PTLDS can be confusing and frustrating, both for patients and healthcare providers. Though the initial infection has been treated, lingering symptoms may impact daily life. This article explores what PTLDS is, its possible causes, symptoms, diagnosis, and current management strategies. What Is Post-Treatment Lyme Disease Syndrome (PTLDS)? PTLDS refers to a set of long-lasting symptoms that continue for 6 months or…

Introduction Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common tick-borne illness in North America and parts of Europe. It is transmitted through the bite of an infected black-legged tick (commonly called a deer tick). The good news is that Lyme disease is highly treatable with antibiotics, especially when caught early. However, treatment protocols vary depending on the stage of the disease, type of symptoms, and age or health status of the patient. This article breaks down the recommended antibiotic therapies, their duration, and what to expect during treatment. Why Early Treatment Matters Early-stage Lyme disease is…
