What is the incubation period for cysticercosis?

The incubation period for taeniasis (intestinal tapeworm infection) can vary, and some individuals may be asymptomatic. Some individuals with taeniasis may develop nonspecific symptoms such as abdominal discomfort, nausea, diarrhea, or constipation about six to eight weeks after ingesting pork containing cysticerci, when the tapeworm has become fully developed.

The incubation period for cysticercosis is variable. Many individuals may remain completely asymptomatic, while others may not develop symptoms from cysticercosis until many years after infection.

Is cysticercosis contagious?

Cysticercosis is not contagious. However, people who carry the intestinal tapeworm (taeniasis) can shed the tapeworm eggs in their feces, and if they practice poor hygiene (not washing their hands after using the bathroom), they can infect others or themselves if the eggs are accidently ingested.
