Dr. Willy Burgdorfer: One Tick at a Time
Dr. Willy Burgdorfer, born on June 27, 1925, in Basel, Switzerland, is known for transforming the understanding of tick-borne illnesses.
Burgdorfer pursued his undergraduate and doctoral studies in parasitology and tropical bacteriology at the University of Basel – where he first developed his fascination with ticks while studying how these arthropods transmitted spirochetes that caused relapsing fever. In 1951, Burgdorfer moved to the United States for a fellowship in Montana at the Rocky Mountain Laboratories (RML) – a National Institute of Health biomedical research facility for vector-borne diseases, such as Rocky Mountain spotted fever, Lyme disease and Q fever.
What Does Lyme Disease Do to Your Body?
What exactly is the connection between a tick bite and lyme disease?
While we’re not sure exactly where and when the disease originated, we do know a lot about how it works, its signs, its symptoms in humans and dogs, how it’s spread and its treatment.

Tick-ing Time Bomb: The Expanding Threat of Tick-Borne Diseases
Urbanization, resistance to pesticides, and, most critically, climate change are creating ideal conditions for global tick proliferation. As these 8-legged bloodsuckers expand their territories, the world should expect a corresponding rise in Lyme disease, spotted fever, Crimean-Congo hemorrhagic fever, tick-borne encephalitis, and other conditions that infect humans, pets, and livestock.
“This is an epidemic in slow motion,” a Centers for Disease Control (CDC) tick expert and research, biologist told the Associated Press.
Ticks live on every continent except Antarctica, and while estimates of annual tick populations vary, the scientific community agrees that their numbers are growing. Researchers also are unanimous that arachnids pose an increasing health risk as mild winters and longer summers associated with global warming kill off fewer individuals, give them longer to develop and feed, and make higher elevations and northerly latitudes that previously were too intemperate or elevated more hospitable.
Lyme Disease Quick Facts
Lyme disease is one of the fastest growing infectious diseases in the country and one of the most difficult to diagnose. Experts in the medical and scientific community, as well as key legislators, have deemed Lyme disease an epidemic … a national public health crisis … and a growing threat.
300,000 people are infected with Lyme disease each yearAt least 300,000 people are infected with Lyme disease each year
New tick-borne diseases are emerging … the number of tick endemic regions is growing … the tick population is increasing … and, the number of people infected with Lyme disease is steadily rising.
The Centers for Disease Control and Prevention (CDC) report that at least 300,000 people are infected with Lyme disease each year in the United States. That’s 25,000 new cases per month. Twenty-five percent of those patients are children, ages 5 to 14.

Shiuly Khatun: Dengue Warrior
Shiuly Khatun is a Field Supervisor at the Dhalpur Aalo Clinic in Dhaka, Bangladesh, where she manages and coordinates the clinic’s operations. Her daily responsibilities are vast and critical, ranging from mapping areas and dividing work for community volunteers to conducting health sessions and overseeing satellite clinic activities.
Dengue fever, once confined to the tropics, now threatens the U.S.
Climate change is expanding the habitat of the mosquitoes that carry the disease, allowing them to spread further north.
Meg Norris was traveling in Argentina in April when the first signs of dengue fever hit her. The weather in Salta, just south of the Bolivian border, was warm, but Norris, a 33-year-old from Boulder, Colorado, zipped a fleece sweatshirt around her body to stop herself from shivering.
“I thought it was sun poisoning,” she said.

The Rise of Dengue: A Global Perspective
Around the world, dengue is considered the most common viral disease transmitted by mosquitoes that affects people. According to the World Health Organization (WHO), the disease is now endemic in more than 100 countries. In the first three months of 2024, over five million dengue cases and over 2000 dengue-related deaths were reported globally. The figures so far project that 2024 could be even worse than 2023, with the regions most seriously affected being the Americas, South-East Asia, and Western Pacific.
In the Americas, there were 6,186,805 suspected cases of dengue reported in the first 15 weeks of 2024. To put this into perspective, according to the Pan American Health Organization (PAHO), this figure represents an increase of 254% compared to the same period in 2023. Of these cases 5,928 were confirmed and classified as severe dengue.
Peter DeChant: Vector Control Visionary
The story of Peter DeChant, a veteran in the mosquito and vector control profession whose journey spans over four decades, is one of dedication, innovation, and relentless commitment to combating mosquito-borne diseases.
Peter’s journey began in 1978 when he became a field technician with Multnomah County Vector Control in Portland, Oregon. Little did he know then that this would mark the start of a lifelong crusade against one of the deadliest creatures on the planet.
By 1983, Peter’s skills and passion for his work led him to the role of Chief Sanitarian, where he led the program for 14 years. It was during this time that he honed his expertise and laid the foundation for his future endeavors.
Mosquitoes that carry West Nile are becoming resistant to insecticides
John VanDenBerg suspects he was gardening when a mosquito got him.
It was September 2018, and VanDenBerg, then 67, had been feeling a little “off” for a few days, he said, like maybe he had the flu.
But one morning, as he was walking out of his Colorado home, he collapsed.
