The best way of dengue prevention is to take preventive measures and stay alert. You must wear light-coloured long-sleeved clothes. Make sure no skin is exposed, especially when moving out. Applying mosquito repellents is also helpful. Stay away from places where mosquitoes can breed. These involve cans, old tires, flowerpots, etc. Change the water that you serve outdoors for birdbaths (if any). Moreover, if a family member gets infected with dengue fever, be careful about it.
