Health Ministry issues Dengue Fever alert
The Ministry of Health says it is putting in place measures to prevent the introduction and spread of the Dengue fever which has claimed about 15 lives in neighbouring Burkina Faso.

According to the ministry, although there is no evidence indicating an outbreak of the disease in Ghana, the risk of an outbreak is high due to the proximity and high density of the vector Aedes mosquito in the country.
“In this regard, there is the need to enhance surveillance and increase awareness among the health staff and general population to prevent, protect against, early detect and appropriately respond to cases,” a statement signed by the Health Minister, Mr Alex Segbefia said.
The ministry further entreated the public to improve environmental conditions to prevent mosquito breeding and protect against mosquito bites to prevent Dengue fever.
Dengue is an acute fever caused by a virus. Burkina Faso has since August and as at November 12, recorded a total of 1,061 probable cases out of 1,266 suspected cases.
What is Dengue Fever
Dengue is an acute fever caused by a virus. It occurs in two forms namely:
- Dengue Fever: presents as febrile illness marked by sudden onset of high grade fever, severe headache and pain behind the eyes, muscles and joints.
- Dengue Haemorrhagic Fever (DHF): is a more severe form. In addition to above, there is bleeding and sometimes shock occurs, leading to death. It is most serious in children. Symptoms of bleeding usually occur after 3-5 days of fever.
- The high fever continues for five to six days (39-40 Degrees Celsius). It comes down on the third or fourth day but rises again. The patient feels much discomfort and is very weak after the illness.
Dengue spreads rapidly and may affect large number of people during an epidemic resulting in reduced work productivity, but most importantly causing the loss of lives.
Signs and symptoms (recognition) of dengue fever
- Sudden onset of high fever
- Severe headache (mostly in the forehead)
- Pain behind the eyes which worsens with eye movement
- Body aches and joint pains
- Nausea or vomiting
Signs and symptoms (recognition): dengue haemorrhagic fever and shock
Symptoms similar to dengue fever as above, plus any one of the following:
- Severe and continuous pain in abdomen;
- Bleeding from the nose, mouth and gums or skin bruising;
- Frequent vomiting with or without blood;
- Black stools, like coal tar;
- Excessive thirst (dry mouth)
- Pale, cold skin
- Restlessness, or sleepiness
Treatment
Treatment is to mostly supportive care with re-hydration and symptomatic treatment improves survival. There is no specific medicine for the treatment of the disease. However proper and early treatment can relieve the symptoms and prevent complications and death.
Aspirin, Brufen and other non-steroidal anti-inflamatory drugs (NSAIDs) should be avoided in dengue fever, as they are known to increase the bleeding tendency and also it increases the stomach pain. Paracetamol can be given on medical advice.
If one or more signs of Dengue Haemorrhagic fever are seen, take the patient to the hospital immediately. Give fluids to drink while transferring the patient to the hospital.
Preparedness Measures and Actions Done:
- Alerts have been sent to all regions and districts to enhance surveillance for early detection, sensitize health staff and provide public awareness.
- Enhanced Surveillance at all levels
- Public education on signs and symptoms and prevention
- We have conducted Entomological Assessment in the affected areas which indicates the presence of Aedes mosquitoes
Mode of spread
Spread of Dengue fever is through the bite of infected Aedes aegypti mosquito.
The mosquito gets the virus by biting the infected persons. The first symptoms of the disease occur about 5-7 days after an infected bite. It is impossible to tell if a mosquito is carrying the dengue virus. Therefore, people must protect themselves from all mosquito bites.
The Aedes mosquito rests indoors, in closets and other dark places. Outside, they rest at cool and with shade. The female mosquito lays her eggs in water containers in and around homes, schools and other areas in towns or villages. These eggs become adult in about 10 days.
Aedes mosquitoes breed in stored exposed water collections and conditions that favour breeding places are as follow:
Barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, discarded bottles, tins, tyres, water cooler, etc. and a lot more places where rain- water collects or is stored.
Preventive measures
Avoid and protect against mosquito bites.
Major efforts of prevention and control should be directed against the mosquitoes. It is important to take control measures to eliminate the mosquitoes and their breeding places. Efforts should be intensified before the transmission season (during and after the rainy season) and at the time of the epidemic.
Prevent mosquito bites. Dengue transmitting mosquitoes bite during the daytime. Individuals must protect themselves from mosquito bites by doing the following:
- Wear full sleeve clothes and long dresses to cover the limbs;
- Use of mosquito repellent is helpful. Care should be taken in using repellents on small children and the elderly;
- Use mosquito coils and electric vapour mats during the daytime to prevent Dengue;
- Use insecticide treated mosquito nets – to protect babies, old people and others, who may rest during the day.
- Curtains can also be treated with insecticide and hung at windows or doorways, to repel or kill mosquitoes.
- Protect people sick with dengue by using mosquito nets and mosquito nets and mosquito coils to help stop the spread of dengue
- Prevent multiplication of mosquitoes:
Mosquitoes, which spread dengue, live and breed in and around houses.
- Cover and drain water from coolers, tanks, barrels, drums and buckets, etc.;
- There should be no water in coolers when not in use;
- Remove from the house all objects which have water collected in them;
- Remove water from refrigerator drip pans every other day;
- All stored water containers should be kept covered all the time;
- Discard solid waste and objects where water collects, e.g. bottles,
tins, tyres, coconut husk, etc.
The World Health Organization (WHO) doesn’t recommend any restriction of travel and trade to the affected country based on the information available on this Dengue fever outbreak.
The Ministry of Health do request intensive public awareness of the disease and direct health workers at all levels to kindly to take this up for action. We further charge the leadership in various health regions and districts to initiate processes for public awareness creation on the disease and related complications, and institute systems for enhanced surveillance, facilities for case management, holding areas and strict adherence for infection prevention and control at all health facilities.
Specifically, we recommend the following to be done in all health institutions and by all health workers:
- Surveillance on Dengue fever and Arbovirus fevers in general (using case definitions) should be enhanced.
- Suspected cases of Dengue fever should be investigated and managed in accordance with guidelines and standard operative procedures.
- Health workers should adhere to regular infection prevention and control (IPC) measures to prevent and protect against possible nosocomial transmission
- Blood sample from suspected case(s) should be taken and safely packaged and sent to Noguchi Memorial Institute for Medical Research (NMIMR) for laboratory investigations
- All levels (National, Regions, Districts and Facilities) are requested to update their preparedness and response plans for Dengue and other Arboviruses in general, sensitize the respective staff and create public awareness.
We wish to assure all Ghanaians that, the Ministry of Health is following with keen interest the progression of Dengue fever in the affected areas. We will not renege on our efforts to protect the people of Ghana.
We have initiated process for preparedness and response mechanisms which has the following major components:
- Epidemiological and laboratory surveillance
- Risk communication-social mobilization and health education which is a major tool in public health
- Case management
- Logistics, security and financial resources and
- Coordination National Coordinating Committee, National Technical Coordinating Committee and EOC meetings on the issue.
