for soil transmitted helminth species, intensity infection is measured by the number of eggs per gram of feces using kato kate technique or others techniques.my question is, this count of eggs reflect really the burden of worm within in the host
Yes the eggs count is the good indicator for the burden of the infection
i say that because i have read in a book intitulate "soil transsmitted helmiminths:Mathematical Models of Transmission, the Impact of Mass Drug Administration and transmission Elimination Criteria".book of J.E. Truscott and al. and that say:As the number of worms increases within the host, the rate at which each female worm produces eggs decrease.i think i didn't understand this sentence.
in my experience Kato Kat's thick smear evaluation is very good for egg counting and accordingly for parasite burden. Go on
Despite possible variations in the number of eggs produced, egg counts nevertheless remain a good indicator of the intensity of infection.
Prevalence and intensity are key epidemiological measures of the status of infection in a certain community. On the other hand, the severity of infection can be measured by the faecal egg count of infected individuals as it is also used as a representative for worm load and infection-induced morbidity.

Heterogeneity in transmission parameters of hookworm infection within the baseline data from the TUMIKIA study in Kenya. page 2. retrieved from https://parasitesandvectors.biomedcentral.com/track/pdf/10.1186/s13071-019-3686-2)
Yes, because if there are so many eggs inside the host it cam also caise to spread them and make the host to die of they are not treated.
