Answer 3

mature/asexual/larval stage

Question 4

the host that harbors the sexual/ mature stage of the parasite

Answer 4

Final/definitive host

Question 5

Paratenic host is:

a. responsible for transmitting the parasite from one host to another
b. allow the parasite’s life cycle to continue and become additional sources of infection
c. transmit same stage to susceptible host
d. parasite does not develop further to later stages

Answer 5

d. parasite does not develop further to later stages

ex: larva will remain until reach susceptible host

Question 6

the period between exposure and the earliest sign and symptoms

Answer 6

Clinical incubation period

bt. exposure and sign & symptoms

Question 7

the period where the development of the parasite in a particular host and the demonstration of the parasite in the different specimens

Answer 7

Biological incubation period

(developed parasite and presence in stool/ specimen

Question 8

an infection where an infected individual is further infected
with the same species leading to massive infection with the parasite.

Answer 8

superinfection/hyperinfection

Question 9

The condition in which

the infection is transmitted from one infected man to another

Answer 9

anthroponoses (human to human)

Question 10

condition where infection is transmitted from animals to humans

Answer 10

zoonoses (animal to human)

Question 11

Answer 11

contaminated soil, water, food
