They take around 2 weeks to hatch. Children can get worms again after they've been treated for them if they get the eggs in their mouth. This is why it's important to encourage children to wash their hands regularly.

Signs & Symptoms. Due to the small number of HPS cases, the “incubation time” is not positively known. However, on the basis of limited information, it appears that symptoms may develop between 1 and 8 weeks after exposure to fresh urine, droppings, or saliva of infected rodents.

The incubation period refers to the time between contracting an infection and experiencing symptoms. The World Health Organization (WHO) note that the typical incubation period for the flu is about 2 days but that it can range from 1 to 4 days. The symptoms of flu typically last about 3 to 7 days in most cases.

While the virus usually causes short-lasting outbreaks, it can be extremely infectious. The incubation period is usually around 24-48 hours but may be as short as six hours. What are the symptoms? The first symptoms are often abdominal pain and nausea.

The infection can then spread from person to person through infected feces. Roundworms can live inside the small intestine for up to 2 years. The worms are about as thick as a pencil. They can grow to be about 13 inches long.

Ringworm has a long incubation period. The red rash can actually take a few days to appear on your skin. If you have ringworm of the scalp, you may not see any signs for a full two weeks after you were exposed. Humans and their pets can share a number of diseases, including ringworm.

At least two or three treatments are needed and are typically performed at two- to four-week intervals. However, none of these treatments will kill the immature forms of the worm or the migrating larvae. The eggs are highly resistant to common disinfectants and even to harsh environmental conditions.

Again, placing fingers in the mouth allows transmission to occur. After the patient is infested, pinworms must hatch and mature before ovipositing begins. The average time from ingestion to detection of eggs in the perianal areas is four to six weeks.

How long does it take for the lesions to appear? The incubation period between exposure to ringworm fungus and the development of ringworm lesions usually ranges from seven to fourteen days; some cases may take up to 21 days before signs of infection develop.

The time between when you eat food containing the parasite and when you first start having symptoms of the disease is generally 7 to 14 days. However, it's possible to start having symptoms as soon as a day after you eat contaminated food. It's also possible not to have any symptoms.

How soon after infection do symptoms occur? The incubation period is usually 8 days but may range from 3 days to 3 weeks. Shorter incubation periods are associated with more heavily contaminated wounds.
517997
Symptoms usually are noticed one to two months after infection. How are pinworms spread? Humans are the only known source of pinworms; pets and other animals do not have pinworms. People become infected when they eat the eggs of the worm.
576442
The incubation period for rotavirus disease is approximately 2 days. Children may develop rotavirus disease more than once because neither vaccine nor natural infection provide full immunity from future infections.
1356549
The incubation period between acquisition of infection and onset of symptoms averages ~1 week (ranges from ~2–14 or more days).
867637
What happens during infection? Once a dog or puppy is infected, there is an incubation period of three to seven days before the onset of first symptoms.
212863
Once the eggs hatch, lice are known as nymphs, an immature form of the parasite that is grayish tan in color. After nine to 12 days the nymphs mature into adults, the average size of which is roughly 2–3 millimeters, or about the size of a sesame seed.

The breeding cycle is approximately 27 days from mating to laying eggs. Worms can double in population every 60 days.
