Title: Dengue Fever is Dangerous

Dengue Fever is Dangerous
  • Mosquitoes are more than Pests

Why is the Threat of Dengue Important to us?
  • Dengue is important to us because it is a serious
    illness it is on the increase in the Caribbean
    and the wider Americas.
  • Dengue Hemorrhagic Fever can cause DEATH.

Dangerous Dengue is on the Increase
  • Dengue is a dangerous illness, it can cause much
    suffering, and in some cases death. Over the past
    decade the Caribbean region has been experiencing
    increased cases of dengue.
  • In 1980, the Caribbean Epidemiology Centre
    reported 20 cases (people) with Dengue Fever.
  • By 1990, this had increased to 616.

Dangerous Dengue is on the Increase continued
  • In re-defining the Caribbean region for our
    purposes as English, French, Dutch and Spanish
    speaking countries from the ABC Islands (Aruba,
    Bonaire and Curacao) and Guyana in the south to
    Cuba and everywhere in between, we learn from the
    Pan American Health Organization (PAHO) that in
    1995, there were 12,830 Dengue Cases and 15
  • 2006 was a record-making year Dengue cases
    reached an unprecedented 32,764. 62 persons
  • The next year, 2007, Dengue cases and deaths
    stepped back slightly to 31,665 and 64
  • Last year, the number of cases nose-dived to
    12,398. The death toll remained relatively high,
    at 43. Now hold on

Dangerous Dengue is on the Increase continued
  • Minus Puerto Rico, the Dominican Republic and
    Cuba, which does not routinely report anyway, the
    Dengue situation would still have reached a peak
    of 23,578 cases in 2006.
  • Dengue infections for this part of the region
    were reduced by half in 2007 to 10,987 cases.
  • That number went down another 50 between January
    and December of 2008 for a total of 4,681 cases.
  • There were 3 Dengue deaths in the Caribbean in
    08, all in Trinidad, compared to 8 the year
    before in just Guadeloupe and Martinique.

Dangerous Dengue is on the Increase concluded
  • On May 08 2009, PAHO records have it that the
    Caribbean had 4,152 Dengue cases, 43 of which
    progressed to Dengue Hemorrhagic Fever (DHF), and
    2 deaths.
  • Add Hispanic Caribbean countries, Puerto Rico and
    the Dominican Republic and you get a further
    1,827 Dengue cases, 55 DHF and 7 deaths.

What is Dengue Fever ?
  • Dengue Fever is an illness that results from
    contracting the dengue virus from the bite of an
    infected Aedes aegypti mosquito that is carrying
    the virus.
  • There are four types of dengue viruses. When a
    person has had one type of dengue virus infection
    once in his/her life, and later gets infected
    with another type of dengue virus, that person is
    in danger of getting Dengue Hemorrhagic Fever.
    This fever can kill.

Signs and Symptoms of Dengue Fever
  • Abrupt onset of high fever
  • Severe frontal headache
  • Pain behind the eyes which worsens with eye
  • Muscle and joint pains
  • Loss of sense of taste and appetite
  • Measles-like rash over chest and upper limbs
  • Nausea and vomiting

Signs and Symptoms of Dengue Hemorrhagic Fever
  • Symptoms similar to dengue fever plus
  • Frequent vomiting with or without blood
  • Internal bleeding which can lead to shock
  • Difficulty in breathing.
  • This fever can be difficult to treat, and in
    some cases even with the best medical care people
    die. Do not wait, see a doctor immediately. It is
    crucial to quickly treat anyone with these

How is Dengue Spread ?
  • Dengue is spread when the female Aedes aegypti
    mosquito bites an infected person, it sucks up
    the blood with the virus and passes this virus
    onto the next person she bites for more blood. In
    this way the mosquito becomes a carrier of the
    dengue virus. We call these carriers of disease
    and illness vectors

How can we prevent Dengue from spreading?
  • There is no vaccine to protect us from Dengue.
  • We must, therefore, protect ourselves by
    avoiding the infection. The only way of becoming
    infected is through the bite of the mosquito that
    is carrying the virus.

We avoid dengue, when we can avoid mosquito bites
  • The Aedes aegypti mosquito that carries the
    dengue virus, likes to lay her eggs in water near
    or in our homes. She enjoys living near to
    humans, her convenient blood supply.
  • Anything that holds water can be a
    mosquito-breeding site. Therefore, the best way
    of protecting your family and community from
    dengue fever is to destroy all the places in
    which the mosquito can lay eggs, breed more young
    mosquitoes, increase their number, and so spread
    dengue to more persons when they bite them for
    their blood. Here are some actions you can take
    to rid your home and community of mosquito
    breeding sites.

Mosquito proof your Cistern
  • Screen Outlets (use 18 screening/mesh wire)
  • Screen Down spouts from the roof
  • Seal points of entry of pipe into cistern
  • Place small fish in your cisterns for these eat
    the mosquito larvae (wrigglers)

Mosquito Proof Ground Level Water Tanks
  • Ensure the cover fits tightly this prevents
    adult mosquitoes from entering and laying eggs.
  • Repair broken manhole covers.
  • Plug overflow holes located under the cover of
    Black Rotoplastic tanks.

Prevent Mosquito Breeding in Flower and Plant Pots
  • Change the water-pots holding your plants or cut
    flowers at least once a week.
  • Drain flower pots flowerpots should have holes
    for drainage
  • Plants should ideally be grown in a mixture of
    sand and water or...
  • Use damp soil instead of water for growing
  • Keep the saucers of flower pots dry

Prevent Mosquito Breeding inside your House and
  • Throw out the water in your draining pan under
    your refrigerator at least once per week
  • Clean and scrub your dish drainers at least once
    per week
  • Toilet flush tanks should be inspected and
    cleaned at least once per week and always kept
    tightly covered
  • Keep surroundings clean and get rid of containers
    which may hold even the tiniest amount of water
    e.g. tins, old tires, old pans, bottles, etc.

Actions to take
  • Punch holes in tins before disposal
  • Get rid of derelict vehicles
  • Ornamental pools and fountains should be
    regularly drained and scrubbed, chlorinated,
    and/or stocked with guppies (fish).
  • Swimming pools should be kept clean, filtered,
    and in good condition.

Community Actions
  • Community members can work together to
  • Keep the environment clean e.g. de-bush empty
  • Keep gullies/ghuts and drains clean
  • Monitor and destroy any other mosquito breeding

Personal Protection
  • People can further protect themselves from
    mosquito bites by using
  • Mosquito coils
  • electric vapor mats
  • Mosquito repellent sprayed on skin
  • Screen windows and doors
  • sleep under mosquito proof bed nets
  • Close windows late evenings and early mornings
  • Wear protective clothing, such as long sleeve
    shirts, long pants, and thick (bobby) socks
    during day time. It is also advisable to avoid
    wearing dark colours.

Community Government -Partners in Dengue
  • Every government takes the responsibility for
    keeping public places free of garbage and junk
    that can become mosquito-breeding places. Your
    Government provides us with information on how we
    can act to protect yourself, and assist us as
    much as possible.
  • But, no Department of Health, no government, can
    come into our homes and workplaces and stop
    mosquitoes from biting us. Only we can do this.
    The government cannot stop the mosquito from
    breeding in our flowerpots or debris left strewn
    in our yards. Only we can do this.
  • If we are serious and determined, we can ensure
    that mosquitoes have no place to breed more
    mosquitoes to bite us and give us dengue fever.
  • So Search and Destroy mosquito breeding places at
    home and work
