Parasite in the City 2: A Growing Threat to Urban Health

As urbanization continues to accelerate, cities are becoming increasingly crowded and complex environments. This provides ideal conditions for the transmission of parasites, which can have devastating impacts on human health.

According to the World Health Organization (WHO), an estimated 3.5 billion people worldwide are infected with parasites. Of these, over 1 billion people live in urban areas. The most common parasites found in cities include protozoa, worms, and arthropods.

Protozoa

Protozoa are single-celled organisms that can cause a variety of diseases, including malaria, amebiasis, and giardiasis. Malaria is the most deadly parasitic disease in the world, killing over 400,000 people annually. Amebiasis is a common cause of diarrhea, while giardiasis can cause abdominal pain, nausea, and vomiting.

Worms

Worms are multicellular organisms that can range in size from microscopic to several meters in length. The most common types of worms found in cities include roundworms, hookworms, and tapeworms. Roundworms and hookworms can cause anemia, while tapeworms can cause abdominal pain, weight loss, and malnutrition.

Mosquitoes can transmit malaria, dengue fever, and yellow fever. Flies can transmit typhoid fever and dysentery. Cockroaches can spread bacteria and viruses.
