A parasite primarily thriving among cats can be a source of unwanted sickness, experts say.

The toxoplasmosis disease, caused by the parasite Toxoplasma gondii, primarily targets cats as its hosts. Cats can spread the parasite through their feces.

Experts warn the public that humans can act as intermediate hosts of the parasite. More often, parasites can enter the human body through ingesting contaminated food.

As cats are oftentimes household pets, a household may be prone to contamination if sanitary measures are overlooked.

According to the World Health Organization, toxoplasmosis is one of the 5 most commonly “neglected parasitic infection” as the parasite Toxoplasma gondii may be considered asymptomatic, or which shows no signs of symptoms among those with strong immunity.

A person with a strong immune system will immediately develop protection against the Toxoplasma gondii parasite, hence avoiding further harmful effects.

However, some individuals may not be as safe. People with weak immunities may still suffer symptoms while pregnant women and their unborn babies could experience worse.

Among the symptoms caused by the disease include body aches, swollen lymph nodes, head ache fever, or fatigue.

Meanwhile, pregnant mothers who suddenly ingest the parasite could possibly contract congenital toxoplasmosis which could lead to fetal death. The parasite can even cause brain or eye damage, and cause abnormal enlargement of a baby’s head.

Experts, however, assure that mothers who have contracted the parasite before pregnancy could be safer as the body may have al
