Cysticercosis in New York

Cysticercosis is a parasitic infection caused by the larval stage (cysticerci) of the pork tapeworm, *Taenia solium*. It occurs when humans ingest tapeworm eggs, leading to cysts forming in various tissues like the brain, muscles, or eyes. This disease is most common in developing regions with poor sanitation and free-ranging pigs. Track Cysticercosis activity and outbreaks specific to New York.

What is Cysticercosis?

The presence of cysts in human tissues was recognized even in ancient times. However, the connection between these cysts, the pork tapeworm (*Taenia solium*), and human disease became clearer in the 19th century with advancements in parasitology. Today, neurocysticercosis is recognized as the leading cause of acquired epilepsy worldwide.

Symptoms

  • Neurocysticercosis (brain cysts): Seizures (most common), headaches, hydrocephalus, focal neurological deficits (e.g., weakness), altered mental status.
  • Muscular cysts: Often asymptomatic, but can cause muscle pain or weakness, or visible lumps.
  • Ocular cysts (eye cysts): Visual disturbances, blurred vision, pain, inflammation, retinal detachment.
  • Subcutaneous cysts: Palpable, movable, non-tender nodules under the skin.

Transmission

Humans contract cysticercosis by ingesting microscopic eggs of the *Taenia solium* tapeworm. This typically occurs through consumption of food or water contaminated with fecal matter from a person harboring an adult *Taenia solium* tapeworm. Direct hand-to-mouth transfer of eggs from an infected individual can also occur. Once ingested, the eggs hatch, and larvae then migrate and form cysts in various tissues.

Contagious Period: Varies by disease

Prevention

  • Wash hands thoroughly with soap and water after using the toilet and before handling food.
  • Cook pork to safe temperatures (minimum 145Β°F/63Β°C with a 3-minute rest).
  • Wash and peel fruits and vegetables, especially when traveling in endemic areas.
  • Ensure access to safe drinking water and avoid unboiled tap water.
  • Improve sanitation and hygiene practices, particularly pig rearing and waste disposal, in endemic areas.
