DISEASES CAUSED BY VIRUSES
It is caused by the measles
virus, transmitted through
air droplets from coughing
or sneezing. Its main
symptoms are fever and
skin rash.
Measles (Campak)
This occurs when virus-
carrying aphids infect plants,
leading to the upward rolling of
leaf margins, often
accompanied by a crunchy
texture when touched.

Bakteri gram negatif kecil ini ditemukan di

terjadi).
Spotted Fever (demam berbintik)
A flaky, white or red rash
between the toes caused
by a group of fungi called
dermatophytes
Caused by the fungus
Botrytis tulipae, leading to
brown spots and withered,
distorted leaves and, in
severe cases, a scorched
appearance

TRANSMISSION CYCLE OF MALARIA

Plasmodium (single-celled
parasites). Once the parasites enter
the body, they travel and
