(i) Wearing socks and full sleeves at night will not prevent the attack from dengue.
(ii) In a slum, many people are reported to be suffering from malaria.
(i) Dengue is caused by bite of Aedes mosquito, which is active during day time, so wearing socks and full sleeves only at night will not prevent the disease.
