what are the symptoms of giardiasis in children, how the infection occurs and
how the disease is diagnosed, we will tell in our article.
Ways of infection with giardiasis
How is giardiasis transmitted? The source of infection is most often

acute intestinal infections.

gas formation in the intestines.
- These symptoms may disappear on their own in 15-20 days, and
Giardiasis can either become chronic or spontaneously
disappear after a few months, which depends on the degree

the number of pathogenic staphylococci, streptococci, candid.
The most accurate factor indicating the diagnosis of giardiasis is
identifying cyst lamblia in the feces of the child. However, due to
undulating selection of parasites with feces, this method with
a negative result should not be taken as a 100% exception
of this disease. One of the modern diagnostic methods for
Today is the definition of specific antibodies to
