Parasites can enter their hosts through various portals, including the skin, mucous membranes, and gastrointestinal tract. For example, some parasites, like hookworms, penetrate the skin directly, while others, such as Giardia, are ingested through contaminated food or water. Respiratory routes are also common for certain parasites, like the larvae of Strongyloides, which can enter through inhalation. Additionally, vectors such as mosquitoes can introduce parasites like malaria directly into the bloodstream.

Parasites can enter the host through various portals, including ingestion (through contaminated food or water), inhalation (breathing in parasite eggs or spores), skin penetration (through insect bites or contact with contaminated soil or water), and sexual transmission (during intercourse).

What are the portals of entry and exit of yellow fever?
The portals of entry for yellow fever are primarily through the bite of infected mosquitoes, particularly Aedes aegypti and Haemagogus species, which inject the virus into the bloodstream. The virus can also enter through broken skin or mucous membranes. The primary portals of exit are through the blood of infected individuals, as the virus can be present in high concentrations in the bloodstream, which can then be transmitted by mosquitoes feeding on them. Additionally, the virus can be excreted in bodily fluids such as saliva and urine, although these are less significant for transmission.

Hosts defend themselves from parasites through various mechanisms, including physical barriers like skin and mucous membranes that prevent entry.

Some hosts also develop tolerance, allowing them to coexist with certain parasites without suffering significant harm.
