Hey there! I’m Alex from MinuteEarth, and today we’re talking about Lyme disease, an illness that’s been getting a lot of attention lately. Even though Lyme disease has been around for thousands of years, it wasn’t until 1976 that it got its name. This happened when many people in Lyme, Connecticut, started showing a strange target-shaped rash, fevers, and joint pain. Doctors found out that these symptoms were caused by a tick-borne disease from a bacteria called Borrelia. Since then, Lyme disease has been on the rise, with hundreds of thousands of people worldwide getting infected every year.
One big reason for the increase in Lyme disease is the mouse. Ticks, which spread the disease, love to feed on the blood of mice and other small animals. Some animals, like opossums and squirrels, eat a lot of ticks, including those carrying the Borrelia bacteria, without getting sick. Mice, however, aren’t great at grooming themselves, so they often carry the bacteria in their blood. This means that when a tick bites a mouse that isn’t already infected, it can pick up the bacteria and later pass it on to humans.
In recent years, changes in our environment have made it easier for mice to thrive. Mice do well in today’s mix of woods, farm fields, and suburbs. The decline of their natural predators has also helped their numbers grow. Plus, climate change has allowed both mice and ticks to move further north because warmer winters no longer stop them. This has led to more infected mice and ticks in places like Canada, China, the Czech Republic, and Connecticut, causing more Lyme disease cases.
Doctors are getting better at spotting Lyme disease symptoms quickly, which means faster treatment for those infected. Scientists and forest managers are working on controlling tick populations using chemicals and by encouraging natural predators of mice. While it’s still unclear how effective these efforts will be, they could help reduce Lyme disease cases if successful.
This video is sponsored by the University of Minnesota, where students, faculty, and staff are tackling big challenges like Lyme disease. Professors in the School of Public Health and the Medical School are studying how tick-borne diseases spread. Meanwhile, experts in the Department of Entomology are learning more about the relationship between ticks and the bacteria they carry. By applying this knowledge, we hope to reduce tick-borne diseases in the future. Thanks, University of Minnesota!
Design a colorful and informative poster that explains what Lyme disease is, how it spreads, and ways to prevent it. Use images and bullet points to make your poster engaging. Share your poster with the class to help raise awareness about Lyme disease.
Work in small groups to create a short skit that demonstrates the life cycle of a tick and how it spreads Lyme disease. Include characters like mice, ticks, and humans. Perform your skit for the class to help everyone understand the process in a fun way.
Choose a specific environmental factor, such as climate change or habitat loss, and research how it affects the spread of Lyme disease. Prepare a short presentation to share your findings with the class, using visuals to support your points.
Imagine you are a journalist interviewing a scientist studying Lyme disease. Write a list of questions you would ask about their research and potential solutions to the problem. Pair up with a classmate to role-play the interview and present it to the class.
Work in teams to create a campaign aimed at preventing tick bites and Lyme disease. Develop slogans, posters, and social media posts. Present your campaign to the class and discuss how it could be implemented in your community.
Sure! Here’s a sanitized version of the transcript:

Hi, this is Alex from MinuteEarth. Lyme disease is an illness that has gained attention in recent years. Although it has affected humans for thousands of years, it remained unnamed until 1976, when many people in Lyme, Connecticut, developed a distinctive target-shaped rash, fevers, and unusual arthritic symptoms. Doctors discovered that they all had a tick-borne disease caused by the Borrelia bacteria. Since then, Lyme disease has seen a significant increase, with hundreds of thousands of people around the world getting infected each year.
A contributing factor to this rise is the mouse. Ticks prefer to feed on the blood of mice and other small mammals. However, some hosts, like opossums and squirrels, consume many ticks, including those carrying the Borrelia bacteria, without becoming infected. Mice, on the other hand, are less effective at grooming and often carry the bacteria in their bloodstream. This means that when a tick bites a mouse that isn’t already a carrier, it is likely to pick up the bacteria and potentially pass it on to humans.
In recent decades, changes in our environment have made mice more prevalent. Mice thrive in today’s fragmented landscapes of woods, farm fields, and suburbs. The decline of their natural predators has also contributed to their population growth. Additionally, climate change has allowed both mice and ticks to spread further north, as warmer winters have removed previous barriers to their expansion. This has led to an increase in infected mice and ticks in various regions, including Canada, China, and the Czech Republic, as well as in Connecticut, resulting in a rise in Lyme disease cases.
So, what are we doing about this? Doctors are becoming more adept at identifying Lyme disease symptoms quickly, allowing for faster treatment. Scientists and foresters are also focusing on controlling tick populations through chemical methods and managing forests to promote natural predators of mice. The effectiveness of these efforts is still uncertain, but if successful, it could lead to a decrease in the prevalence of Lyme disease.
This video was sponsored by the University of Minnesota, where students, faculty, and staff across various fields are working to address significant societal challenges, including public health issues like Lyme disease. Professors in the School of Public Health and the Medical School are researching how tick-borne diseases spread, while experts in the Department of Entomology are enhancing our understanding of the biological relationships between ticks and the pathogens they carry. Applying this knowledge will help reduce the incidence of tick-borne diseases in the future. Thank you, University of Minnesota!

Let me know if you need any further modifications!
Lyme – A disease caused by bacteria transmitted through tick bites. – Example sentence: Lyme disease can cause symptoms like fever and fatigue if not treated promptly.
Disease – A condition that negatively affects the normal functioning of an organism. – Example sentence: Scientists are studying how diseases spread in different environments to better understand their impact.
Ticks – Small arachnids that feed on the blood of mammals, birds, and sometimes reptiles and amphibians. – Example sentence: Ticks can carry bacteria that cause Lyme disease, making it important to check for them after hiking.
Mice – Small rodents that are often used in scientific research and can be hosts for ticks. – Example sentence: Mice play a crucial role in the ecosystem but can also spread ticks that carry Lyme disease.
Bacteria – Microscopic single-celled organisms that can be beneficial or cause diseases. – Example sentence: The bacteria that cause Lyme disease are transmitted to humans through tick bites.
Environment – The surrounding conditions in which an organism lives, including air, water, and land. – Example sentence: Changes in the environment can affect the population of ticks and the spread of Lyme disease.
Climate – The long-term pattern of weather in a particular area. – Example sentence: Warmer climates can lead to an increase in tick populations, raising the risk of Lyme disease.
Predators – Animals that hunt and eat other animals for food. – Example sentence: Predators like birds can help control the population of mice, which are hosts for ticks.
Symptoms – Signs or indications of a disease or condition. – Example sentence: Early symptoms of Lyme disease include a rash and flu-like feelings.
Research – The systematic investigation into and study of materials and sources to establish facts and reach new conclusions. – Example sentence: Ongoing research aims to find better ways to prevent and treat Lyme disease.
