Hot tick is here in summer. Here’s what you need to know and how to stay safe

The summer in the United States is in full swing now. This means avoiding the octopus ticking, which means a lot of outdoor fun, sunshine, and unfortunately for many of us, it means very little.

Tickworms and many diseases they carry, such as Lyme disease, are growing public health threats. For example, just this week, the latest data from the Centers for Disease Control and Prevention showed that the largest number of tickworm-related emergency room visits have been recorded so far in 2025. Although the worst tickworms are particularly common in the Northeast, they are particularly common with disease populations, but continue to spread steadily and continuously, which is a further spread of our entire scientists and can still spread new viral and bacteria through tigesia and bacteria.

As Americans are firmly firm in the hot summer, Gizmodo contacts Dennis Bente, professor of microbiology and immunology at the University of Texas Medical. We talked with Bente about why tickworms become a bigger problem, now is the best way to protect themselves from them, and potential innovations that may ultimately help us defeat the tickworm threat. The following conversation has been edited in detail for syntax and clarity.

Ed Cara, Gizmodo: I live in the northeastern United States and my friends and family, especially dog owners, often complain about the need to look for tick bugs faster than ever before. Is the ticking season really getting longer? What seems to be the main reason?

Bente: Yes, your friends and family’s observations are absolutely correct. The tick season in the northeastern United States has indeed become longer and more intense, and the expansion of the tick activity period and the growth of the tick population has been confirmed by multiple scientific studies.

Once a relatively predictable seasonal threat has evolved into a year-round focus in many areas. There is evidence that ticks are now active in winter due to climate change, and adult deer are active in temperatures as low as 14 degrees Celsius [-10 degrees Celsius]. This leads to a year-round alert demand, as ticks appear now whenever there is no ticking on the ground and the temperature exceeds freezing, extending its season beyond the traditional month. Warming will accelerate Tick development, increase survival, and expand northward about 28 miles [45 kilometers] Every year, especially in the Northeast. Tick populations are also promoted by providing ideal habitats and ideal habitats and microclimate systems that are conducive to Tick survival, factors such as restoration of deer populations, afforestation, landscape splitting and suppression of fire extinguishing.

Gizmodo: People may be most familiar with Lyme disease when it comes to ticking bacteria. But there are many more. What are some of the little-known tickworm diseases that make you wake up at night? Are these diseases (such as Lyme) becoming more common?

Bente: Although Lyme disease occupies public awareness of tickworm disease, it only represents the tip of a larger iceberg.

The Powassan virus (POWV) stands out and is perhaps the most feared tick insect pathogen in North America. This flavivirus causes severe encephalitis with a mortality rate of nearly 18.8%, while the neurological consequences of 72.7% of survivors have devastating consequences. Unlike other tickworm diseases, POWV can spread within just 15 minutes of the tick attachment, which gives the victim little chance to remove tickworms.

There are other little-known viruses. Heartland virus emerged in 2009 and has since been recorded in more than 60 cases in 14 states, with an estimated mortality rate of 5-10%. Bourbon virus (BRBV) was first identified in 2014 and remains little known. There are only five human cases in Kansas, Oklahoma and Missouri, but blood tests show it is more extensive.

Borrelia Miyamotoi Causes hard ticking fever, which is often not yet discovered despite being transmitted by the same ticks carrying Lyme disease. Between 2013 and 2019, 300 cases were identified through surveillance in only nine states that conducted active surveillance. Since the disease is often misdiagnosed, this may represent a massive underestimation.

There are also Ehrlichia There is also the spotted fever group Riquesia, which represents a growing and increasingly complex threat. Rocky Mountain found a fever (Riksey) remains the most severe newly recognized Rick pathogen, which may lead to similar serious diseases.

Overall, tickworm disease is definitely becoming more common. The evidence is overwhelming: The number of ticking disease cases in the United States increased from 40,795 (2011) to 50,856 (2019).

Gizmodo: Are there any vaccines, vaccines or other innovations under development that can help us beat these bacteria?

bending: Yes, there are indeed promising treatments, vaccines and innovative technologies that can help us eventually get the field of anti-tick disease.

This is coming: the most important immediate breakthrough is VLA15, the first Lyme disease vaccine to be conducted in late-stage clinical trials for twenty years. Developed by Pfizer and Valneva, this represents a significant advancement in previous failed attempts. The vaccine has completed recruitment for its Phase 3 Valor trial, recruiting 9,437 participants in the United States, Europe and Canada. The results are expected to be by the end of 2025 and potential regulatory approvals in 2026.

Perhaps more exciting than pathogen-specific vaccines are anti-fingered vaccines that can prevent multiple ticking diseases by targeting the tickworm itself. Researchers have developed mRNA-lipid nanoparticle vaccine containing tick saliva protein cocktails. The most advanced formula is the 19isp vaccine. This vaccine causes rapid erythema development in the skin, early tick cleavage, and reduces tick feeding by generating an immune response to alert the presence of host tick worms and prevent pathogen transmission when ticks are quickly removed.

TP-05 is a research-based oral, systematic, Lotilaner developed by Tarsus Pharmaceuticals. It represents a revolutionary approach to preventing ticking diseases. This isoxazoline compound has successfully completed a Phase 2A human trial, showing that the tick mortality rate is 97% within 24 hours after attachment, and a single dose provides at least 30 days of protection. Since ticks usually require 36 to 48 hours of fixation to spread Lyme disease, killing them within 24 hours provides efficient prevention and excellent safety in healthy volunteers.

Gizmodo: Meanwhile, how do we best prevent these tiny pests from destroying our outdoor time?

Bente: For reliable tick protection, the CDC recommends EPA-registered repellents containing DEET, PICARIDIN, IR3535 or Lemon Eucalyptus Oil (OLE). Studies consistently show that DEET concentrations from 20% to 30% provide the most effective protection with a power efficiency of 85% to 89%.

Permethrin, easily available in the store, is perhaps the most powerful weapon in the anti-challenge arsenal. Unlike the repellent that simply stops the tickworm, permethrin actually kills the tickworm when it comes into contact. When applied to clothing, it can provide protection for up to six weeks or six washes. The effectiveness is significant: permethrin-treated clothing has shown nearly 100% protection against tick attachments.

Your clothing choice can serve as your first line of defense. Wear light-colored clothes to make ticks easier to spot. Long-sleeved shirts, trousers and closed shoes provide physical barriers and tucked into pants and pants, which can provide additional protection by eliminating entry points.

Stay in off-road centers and avoid lush forest areas during peak tick season (April to September). Daily tick checks are the most critical preventive measures. Most tickworm diseases require 24 to 48 hours of fixation for transmission, so rapid deletion will greatly reduce the risk of infection. Use a mirror to examine the entire body and focus on warm areas: groin, armpits, scalp, ears and knees, and belts. Even in the yard, children and pets are checked every day and bathed within 2 hours to wash away crawling ticks.

To remove correctly, use fine-tip tweezers to grab the ticking close to the skin. Stable pressure pulls upwards – don’t twist or assholes. Do not squeeze, crush or burn tick. Clean the bite area and hands with alcohol or soap. If symptoms develop, make sure to photograph ticks for identification and avoid civil remedies such as matches or nail polish, which can increase the risk of disease transmission.
