Powassan virus disease is a tick-borne illness that can be more serious than Lyme disease and can lead to severe neurological problems. Here is some important information about Powassan virus disease:
1. Rarity: Powassan virus disease is considered rare. Between 2015 and 2021, there have been an average of only 26 cases reported in the United States, according to the Centers for Disease Control and Prevention (CDC). In comparison, Lyme disease is the most prevalent tick-borne illness, with about 30,000 cases reported each year.
2. Rise in cases: While Powassan virus disease is rare, cases have been increasing since 2012. The number of reported cases has been on the rise, with 7 cases in 2012, 39 cases in 2019, 20 cases in 2020, and 23 cases in 2021.
3. Transmission: People can get Powassan virus disease from being bitten by infected ticks. The blacklegged or deer tick, woodchuck tick, and squirrel tick are the three types of ticks that can spread the virus. These ticks are mostly found in the northeastern and Great Lakes regions of the United States.
4. Symptoms: Powassan virus disease does not typically cause distinctive rashes like other tick-borne illnesses such as Lyme disease. Initial symptoms are often flu-like, and more severe symptoms can include confusion, loss of coordination, and seizures. Diagnosis can be made through blood or spinal fluid tests.
5. Risk factors: People who work or engage in outdoor activities in areas where infected ticks are prevalent face an increased risk of Powassan virus disease. Older adults and immunocompromised individuals, especially those taking immunosuppressive medications, are more susceptible to severe cases of the disease.
6. Fatality rate and long-term effects: Powassan virus disease has one of the highest fatality rates among tick-borne diseases in the United States. About 1 in 10 people with severe cases of the disease die. Additionally, approximately half of those who survive the severe disease may experience long-term health problems, such as recurring headaches, loss of muscle mass and strength, and memory problems.
7. Contagion: Powassan virus disease is not contagious through coughing, touching, or sneezing. There have been a small number of documented cases of person-to-person transmission through blood transfusion.
8. Prevention: The best way to avoid Powassan virus disease is to prevent tick bites. Thoroughly check your body and clothing for ticks after spending time outdoors. You can also treat your clothing with tick repellent, wear long pants, and tuck them into your socks. Showering within two hours of coming indoors and tumble drying clothes on high heat can reduce the risk of tick-borne diseases.
9. Rising tick-borne illnesses: Tick-borne illnesses, including Powassan virus disease, have been on the rise due to factors such as expanding tick populations and territories. Climate change, which creates longer warm seasons, contributes to the spread of ticks.
10. Other tick-borne illnesses: Lyme disease is the most common tick-borne illness, followed by anaplasmosis and babesiosis. Each of these diseases has its own symptoms, treatment options, and preventive measures.
11. Pets and Powassan virus: There have been no known cases of Powassan virus infecting pets like dogs and cats. However, pets can bring infected ticks into the home, so it’s important to check them for ticks after they’ve been outside.
It is essential to stay informed about tick-borne illnesses, take precautions to prevent tick bites, and seek medical attention if you experience symptoms or suspect exposure to ticks carrying Powassan virus.
