Dengue Fever is a viral disease with flu-like symptoms. The disease is spread by mosquitoes but unlike malaria mosquitoes they can be found in the city areas in daylight hours.
Anti-malarial tablets do not offer any protection against dengue fever. Insect avoidance measures offers the best protection against dengue. Dengue viruses are found in many countries of the Caribbean, Central and South America, Mexico, the Pacific Islands, most tropical countries of Asia – including Singapore – and parts of tropical Africa.
Cases of Dengue Fever in most tropical areas have increased in recent years. Major outbreaks have occurred in the Pacific region and in North Queensland – Australia. The symptoms – fever, severe headaches, joint and muscle pain, rash and sore throat – usually appear 5-8 days after being bitten by the offending mosquito.
The rash, which develops on the 3rd to 5th day of the illness, spreads from the stomach to the arms, legs and face. A few days after the rash appears, the fever breaks and recovery begins.
Dengue Haemorrhagic Fever is a rare but potentially fatal complication of Dengue Fever. This is more common in India and South East Asia, particularly amongst those who have had dengue fever before. International Medical Clinic suggests any persons suspected of having dengue fever should be observed for signs of bleeding or bruising and seek urgent medical attention if this happens.
