Symptoms of dengue usually develop suddenly 4 to 10 days after becoming infected like; a high temperature (fever), severe headaches, pain behind the eyes, etc. The symptoms normally pass in about a week, although you may feel tired and slightly unwell for several weeks afterwards.
In rare cases dengue can be very serious and potentially life threatening. This is known as severe dengue or dengue haemorrhagic fever. People who've had dengue before are thought to be most at risk of severe dengue if they become infected again.
There's currently no widely available vaccine for dengue. You can prevent it by avoiding being bitten by mosquitoes, use insect repellent, wear loose but protective clothing, etc.
There's no cure or specific treatment for dengue. Treatment involves relieving your symptoms while the infection runs its course. You can usually look after yourself at home. Take paracetamol to relieve pain and fever, drink plenty of fluids, etc.
