(i) Before travelling, visit a doctor for preventive medicines and pack mosquito repellents, nets and long-sleeved clothes. During the trip, stay indoors after dusk, apply repellent regularly and sleep under a mosquito net. Avoid areas with stagnant water. After returning, monitor for symptoms like fever, chills or weakness. If any appear, consult a doctor immediately. These steps help prevent malaria and ensure a safe trip for the whole family.

(ii) I’d explain to my sibling that malaria spreads through mosquito bites and that mosquito nets and repellents act like shields. Nets protect us while we sleep and repellents keep mosquitoes away during the day. I’d say, “Just like we wear jackets to avoid cold, nets and creams protect us from bites.” By making it easy to understand and showing care, I’d help them take these precautions seriously and willingly.

(iii) Ignoring health advisories in malaria-prone areas can lead to serious illness. Travellers may get infected through mosquito bites and suffer from high fever, chills and weakness. Some may require hospitalization. If they return home sick, the disease might spread to others. Missing out on preventive steps like using nets or medicines increases health risks. Health advisories are given to protect everyone’s well-being and should always be followed carefully.
