Q

Mr. X during the recent GCQ went to Tagaytay to visit his friends for 3 days.
Little did he know, the President will revert his announcement from GCQ to
MECQ. Due to lack of transportation, he was forced to walk from Tagaytay to
Fairview. While traversing the secluded area of Aguinaldo Highway, Mr. X got
thirsty hence he opened his can of soda. He got starved so he bought food
from a timely passing taho peddler. He decided to rest for a while, sat on a
huge slab of stone where the back portion is covered with green vines and
vegetations but adjacent to that was a deep ravine. When he decided to lean
his back, he fell and went inside a huge tunnel-like sliding cave with clean
and refreshing water, smooth surface but with dark surroundings and
seemed without ending. After an agonizing 1 hour of continuous sliding,
tumbling, and freewheeling in a long and winding tunnel, he reached the very
end of it which happened to be the main water gate of La Mesa Dam, thereby
cutting short his trip from Cavite to Fairview. After which Mr. X developed
fever, frequent diarrhea with blood on his stool and after 2 months of that
incident, he developed chronic granulomatous lesion.
The infective stage of Mr. X’s infection is which of the following forms?
1. Cyst
2. Trophozoite
3. Promastigote
4. Trypomastigote

Q

Mr. C and Mrs. D during the GCQ decided to go to sandy beaches in Thailand
to unwind with their children A and B for 3 days. In Thailand, they decided to
go to Phuket, little did they know, and since Mr. C and Mrs. D are not familiar
with the route, they reached a secluded beach instead of Phuket. A and B, to
their dismay, started to throw tantrums prompted their parents Mr. C and Mrs.
D to just enjoy the sea, leaving the two children behind. A and B sat on the
sand which they found a little bit itchy and seemed to have sand flies. After a
while, A and B joined their parents in swimming. The water is not that clear
and with a foul odor. Then, the 2 hours became 4 and the 4 hours became 6.
With so much drinking, eating with the food they bought in the street, and
swimming, it was already nightfall when they decided to leave the area. A
week after their return in the Philippines, B, one of the children, developed mild
diarrhea, anorexia, and a full blown malabsorption syndrome.

D to just enjoy the sea, leaving the two children behind. A and B sat on the

swimming, it was already nightfall when they decided to leave the area. A

Q

Mr. A and B during the recent ECQ went to Gubat sa Ciudad Resort to have a
drinking spree and to swim with their friends for about 2 hours. Little did they
know, a concern citizen phoned the IATF and the LGU of Caloocan and
reported the illegal activities being held in the resort. Mr. A and B were
accosted by unknown personnel, while their friends were able to flee. The two
were brought in a secluded place with a man-made lake with a depth of
about 2 meters. The water is somehow muddy because of dead vegetations
and with a foul odor. The unknown personnel started to interrogate them but
Mr. A and B insisted that they should be brought in a nearest police station.
The captors paid no heed to their demand, instead they started to tease Mr.
A and B and the two unfortunately fell in the said dirty lake. Timely, the real policemen were able to follow the unknown personnel and rescue Mr. A and B and were released thereafter after giving citations for violating the IATF
Guidelines. A day after the incident, Mr. A developed fever followed by a rapid
onset of nausea and vomiting
accompanied by generalized seizures and
Kernig’s signs. 6 days after the onset of the symptoms, Mr. A died.
