Types of Parasitic Infections

There are three main types of parasitic infections: protozoa, helminths, and ectoparasites. Each one is treated differently and has its own unique timeline for removal.


Protozoa are single-celled organisms that can cause a variety of illnesses. These illnesses can range from gastrointestinal issues to malaria. The time it takes to kill these parasites can vary depending on the severity of the infection. Typically, treatments for protozoa take between 7–14 days to work.


Helminths are worms that can range from flatworms to roundworms. These internal parasites are often contracted from contact with contaminated soil, water, or food. It usually takes between 1–3 weeks for treatments to kill helminth parasites.

Ectoparasites, such as fleas, lice, mites, and ticks, are organisms that live on the surface of the host. Treatments for ectoparasites, such as insecticides, often take effect within 24 hours.

Preventing Parasitic Infections

In order to minimize the risk of contracting parasites, here are some simple steps you can take:

  • Wash your hands regularly with soap and water
  • Drink only clean, purified water
  • Avoid contact with animal waste
  • Wear appropriate clothing when outdoors
  • Cook food to a safe temperature
  • Check your pets for signs of parasites on a regular basis


It is important to know how long it takes for treatments to kill parasites. Protozoa and helminth parasites can take between 7-14 days and 1-3 weeks to be eliminated, respectively. On the other hand, ectoparasites can be removed within 24 hours. It is also important to practice preventive measures, such as regularly washing hands and cooking food to a safe temperature, to avoid contracting parasites in the first place.
