The tropical skin disease called yaws is transmitted by direct contact. Its causative agent, Treponema pallidum pertenue, is indistinguishable from T. pallidum. Syphilis epidemics in Europe coincided with the return of Columbus from the New World. How might T. pallidum pertenue have evolved into T. pallidum in the temperate climate of Europe?

What is the significance of the behavior of the vectors that allow La Crosse encephalitis to persist in the eastern US while Malaria is mostly eliminated.
Hello,
What else would you add to this explanation about "Ascaris lumbricoides", can be any cusious fact about it :)
Ascaris lumbricoides, commonly known as the human roundworm. It is a parasitic worm that infects about 772–892 million people worldwide. It belongs to a group of parasites known as soil-transmitted helminths (STH), which are spread through contact with contaminated soil. The adult worms live in the human intestine, where they can cause various health problems, especially in children. Infection usually occurs when a person consumes food or water contaminated with infective Ascaris eggs from soil. This is common in areas with poor sanitation and hygiene practices, especially in tropical and subtropical regions of Asia, sub-Saharan Africa, and the Americas (About Ascariasis, 2024).
The life cycle begins when an infected person’s feces contaminates soil with Ascaris eggs. These eggs mature and become infective, spreading to humans through ingesting contaminated food or…
