Where it’s common: India, Southeast Asia, Southern China and Africa.
Where it’s common: Yet another mosquito-borne tropical disease that’s on the rise, 80 per cent of dengue cases are asymptomatic, but can morph into sudden onset fever, weakness, nose bleeds, easy bruising and a headache typically experienced behind the eyes. Depending on the severity of the case, treatment can include oral or intravenous rehydration or a blood transfusion. For quick pain relief, opt for acetaminophen tablets instead of aspirin, which could worsen bleeding. As per usual, standard protocol is to ward against the illness with liberal use of insect repellant, long sleeves and netted sleeping grounds.
