Infant Hospitalized After Tick Bite in Boston

A 5-week-old baby named Lily Sisco is currently battling for her life after a tick bite during a family walk on Martha’s Vineyard. Her mother, Tiffany Sisco, recounted to local news outlets how she discovered a tiny tick on Lily’s ankle after their outing. A week later, Lily developed a high fever of 102 degrees, prompting her parents to seek emergency medical care. The baby was subsequently transferred to Massachusetts General Hospital in Boston for specialized treatment.

Severe Symptoms and Intensive Care

Upon arrival at the hospital, Lily began experiencing seizures, leading to her admission into the Pediatric Intensive Care Unit (PICU). According to a GoFundMe page set up for the family, Lily has sustained brain damage due to an infection. She is under constant monitoring and receiving large doses of seizure medication to prevent further neurological harm.

Possible Powassan Virus Infection

Health officials suspect that Lily’s condition may be linked to the Powassan virus, transmitted by infected deer ticks. This virus is known for its rapid transmission compared to Lyme disease, with an incubation period ranging from one to four weeks. Although rare, with only seven to eight cases reported annually in the U.S., the incidence of Powassan virus has been increasing, particularly in the Northeast and Great Lakes regions.

Tick Activity and Public Health Concerns

Research indicates that 1% to 2% of nymph deer ticks on Martha’s Vineyard carry the Powassan virus. These ticks are most active from May through July, coinciding with peak outdoor activity and tourism on the island. The virus can lead to severe illness, including brain inflammation and seizures, with older adults, children, and immunocompromised individuals at higher risk.

Preventive Measures Against Tick-Borne Diseases

Experts emphasize the importance of preventing tick bites as the most effective strategy against Powassan virus and other tick-borne diseases. Recommended measures include using EPA-registered insect repellents with at least 20% DEET, wearing protective clothing, and conducting thorough tick checks after outdoor activities. Additionally, maintaining short grass and creating barriers like gravel or wood chips can help reduce tick presence in residential areas.
