BEAT the bite

Arm yourself against an emerging threat

Warm weather beckons sun enthusiasts and nature lovers outside to enjoy the great outdoors. But humans aren’t the only species that thrive in warm weather. Bug populations boom when plants bloom, causing not only itchy stings and painful bites, but harmful infectious diseases that can be life-threatening without proper diagnosis and treatment.

Because the planet’s tiniest predators flourish in warmer weather, the threat they pose has increased as the earth’s temperature has increased. The longer summers, milder winters, and shifting climate zones brought on by rising global temperatures have triggered a migration of ticks, mosquitos, and insects into previously uninhabitable climates zones,1 broadening the impact of the infectious diseases they carry.


17% of all infectious disease is vector-borne2


1 million worldwide deaths annually due to vector-borne illness3


640,000 cases of vector-borne disease in the U.S. reported from 2004–20164

Amplify awareness

Diseases previously limited geographically, such as Lyme disease, have expanded into new regions and are appearing earlier each season as their vectors adapt to warmer temperatures. And illnesses once thought to be rare, such as Powassan virus neuroinvasive disease,5 have increased due to climate redistribution. Additionally, the ease of international travel can bring imported diseases such as malaria to all corners of the world. This changing vector-borne disease landscape demands an increased awareness of disease prevalence within geographic regions, but also knowledge of the latest testing methodologies to procure accurate answers for patients.

Mayo Clinic Laboratories offers a robust menu of vector-borne testing, including individual tests and panels that aid in diagnosing illness caused by ticks, mosquitos, and other insects. From common endemic and imported diseases in the U.S. and Canada, such as Lyme disease and Chagas disease, to more rare illness, such as Zika virus infection, malaria, Powassan virus infection, Tularemia, and Rocky Mountain spotted fever, our testing spans the spectrum of vector-borne diseases. We can provide you with tools to accurately diagnose patients and set them on a path toward healing.

As warm weather returns so do vector-borne diseases transmitted by ticks and mosquitos.  In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Department of Laboratory Medicine and Pathology at Mayo Clinic, and William Morice II, M.D., Ph.D., president and CEO of Mayo Clinic Laboratories, discuss the increasing rates of tick-borne diseases and how to test for and prevent them. Listen to learn more.

In this "Hot Topic," Elitza Theel, Ph.D., discusses laboratory utilization management, specifically for diagnostic testing for tick-borne diseases. Watch now to learn more.

Testing guidance by area of exposure

Whether your patient was exposed at home or while traveling, our ordering guide by region can help determine the prevalence of vector-borne diseases in distinct geographic regions.
