Prevention of Dengue Fever

There are a several cases of Dengue Fever. We would urged our members to maintain strict environmental hygiene, mosquito control and personal protective measures both locally and during travel.

Dengue fever is an acute mosquito-borne infection caused by the dengue viruses. This is found in tropical and sub-tropical regions around the world. For instance, dengue fever is an endemic illness in many countries in South East Asia. The dengue viruses encompass 4 different serotypes, each of which can lead to dengue fever and severe dengue (also known as 'dengue haemorrhagic fever').

Dengue fever is clinically characterised by high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, swollen lymph nodes and rash. Some infected people may not develop apparent symptoms, and some may only have mild symptoms like fever, e.g. young children may exhibit a milder non-specific febrile illness with rash.

The incubation period of dengue fever ranges from 3 – 14 days, commonly 4 – 7 days. Members who feel unwell should seek medical advice promptly.
