hot country thick with humidity can close around you: grass is wide at the
bottom and angled like so many swords. The foliage, dense and matted,
looms threateningly. Flowers are large, blood-coloured, orange, yellow,
without fragrance, appear plastic. All around are signs of decay. Guavas
riddled with worms are crushed underfoot into pulp. Papaws rot on a
kitchen counter. In a forgotten vase, stems rot into water leaving a

creaking frogs, a mad man shouting obscenities, randomly, to no one in
particular. A mosquito wheels about mockingly, escaping the swatter
easily, swooping down, swaying menacingly, then flying out of reach.

images of a half drunk glass of water, left overnight under the bed, an
itch on your arm, are now, ridiculously, intimations of death. In this
land where the lines between folklore, heresy, myth, truth and prejudice
are blended into a blurred hysteria it is difficult enough simply to
establish facts. Between conjecture and media reports, this is what I
managed to establish:
women have died from Dengue Haemorrhagic Fever (DHF). There are 30
confirmed cases of DHF. At the San Fernando hospital more than 220
patients with dengue-like symptoms have been admitted for observation.
Overcrowding was severe and at one point up to five patients were
occupying one bed. It was reported that patients who might have gone into
shock and begun to bleed from DHF on a weekend ran the risk of bleeding to
death since the hospital did not have adequate supplies of life saving
platelets - blood cells which help clotting.
was too little to go on. I could no longer look at a glass of water
standing still on a table for five minutes without thinking of DHF. So I
did what all hypochondriacs do. Called the doctors: the closest we
hypochondriacs will ever get to divinity because we trust them with our
neuroses. But they are wary of journalists, of our capacity to alarm or
twist their replies into sensationalism. I was lucky to be put on to Dr
James Hospedales at Carec, by a helpful doctor at PAHO. I also used the
Net. My questions to doctors and the “search” on the Net reflected
paranoia, hysteria, megalomania. The questions tumbled out. Was it true
that that there was an epidemic, that Dengue Haemorrhagic Fever was fatal,
that it came about because we were not spraying for mosquitoes? Was it
are the facts as I now understand them, gleaned from these various
reliable sources. Firstly there is a dengue outbreak, but no epidemic in
Trinidad and Tobago. Dengue fever is transmitted through the bite of an
infected female Aedes aegypti mosquito. It affects as many as 50 million
people worldwide each year. There has been a recent outbreak in Cuba and
dengue remains a major health risk in Africa, South and Central America
and southern areas of the United States. The dengue virus, most prevalent
in Third World tropical regions but also found in subtropical developed
countries, causes dengue fever, a severe, flu-like illness. The dengue
virus has circulated in the tropical world for generations. Symptoms
include pain to the joints and muscles, headaches, sore throat, fever,
runny eyes, and an irritating rash. There is no cure, but recovery usually
occurs within several days.
fever is part of a vicious cycle: the Aedes aegypti mosquito is infected
when it bites a person who has dengue. Then the mosquito, now a carrier of
dengue in turn infects people. If you are bitten by an infected mosquito,
you have an incubation period of a week to ten days before you get ill
with symptoms. On the day before you fall ill and for four days afterwards
you have the virus in your blood stream. In order to break the cycle and
prevent the spread of the virus it is vital to prevent the person who has
dengue fever from being bitten during the incubation period. This can be
done by spraying the patient’s walls with insecticide. (A vital and
underrated aspect of prevention.) The dengue infection, however, cannot be
passed on through direct contact with a person who has the virus.
Haemorrhagic Fever (DHF) is a severe, frequently fatal infection caused by
one of several dengue viruses (there are four “types”) and is also
spread by the bite of female Aedes aegypti mosquitoes. Anybody getting a
dengue infection is at risk of getting DHF, but it’s very low if it’s
the first time you are getting infected by dengue or a long time since
your last infection. DHF generally occurs when several types of virus are
present at the same time or when the patient has contracted a second or
third dengue virus after previous infections by another type. The overall
risk of DHF has increased in Trinidad and Tobago due to the heavy outbreak
of dengue fever of the type 1 virus last year. Those who contract dengue
for the second and third time before they have become immune to the virus
are the most susceptible to the Dengue Haemorrhagic Fever. Their blood
vessels become leakier and leak plasma, there is hemorrhaging, the liver
swells, and the patient suffers from sudden and severe abdominal pains.
“A one two combination punch in quick succession,” as Dr Hospedales
put it. No one type of dengue is intrinsically bad. It the sequential
fever that sets us up DHF.
is believed that the various types of dengue virus are brought back to
Trinidad by people who travel to countries where they exist. Infections of
any one type of dengue dominate a population for a few years until people
become immune to it. Then another type against which there is no immunity
is introduced to a population, causing infection. The early symptoms of
Dengue Haemorrhagic Fever (DHF) are similar to those of dengue fever but
after several days the patient becomes irritable, restless and sweaty
followed by a shock-like state. Bleeding may appear as pinpoint spots of
blood on the skin and larger patches of blood under the skin. Bleeding may
occur from minor injuries. Death generally occurs from shock. If the
patient survives, recovery begins after a one-day crisis period. DHF
deaths are preventable if symptoms are recognised and treated early
enough. The treatment largely consists of replacing lost fluids. For those
under observation it can take anything from three days to three weeks to
get a confirmed diagnosis, depending on how far the disease has
of people have dengue to various degrees but Dr Hospedales says it is
neither necessary nor practical to admit all of them to hospital. Doctors
need to make a judgment call. People with dengue-like symptoms need to be
told to watch for the danger signs. If they bleed easily or profusely,
start coughing blood, are restless, sweaty, or suffer from abdominal pain
then they need to go to the hospital immediately. Basic dengue lasts for
between five and seven days and recovery is complete. Even patients
recovering from DHF have long term complications. However, patients may
suffer from post viral fatigue which can last up to four weeks.
are no commercially available dengue vaccines available although vaccine
research has been going on for some time. Many people with dengue fever
have mild symptoms or no symptoms at all. This is where the general
campaign to eliminate the breeding Aedes aegypti is so important. The
mosquito breeds in clear water, and it doesn’t need a lot. It especially
thrives in a human domestic atmosphere, and lives under beds, on walls.
Water lying in a child’s plastic boat in a bath could do it, or
rainwater in a brick, or water in a vase. These are all breeding grounds,
anything that will collect water.
big producers are the big uncovered drums and tanks with water. You get
rid of the mosquitoes by spraying with insecticide inside and outside the
house. It is impossible to get rid of mosquitoes in one home because they
come in from the outside so entire communities need to band together both
to prevent breeding and to eradicate them by spraying.
surprise in my investigation was the conclusion that the effectiveness of
spraying was limited, like spinning top in mud. Apparently (although I was
not able to confirm this) the Ministry has been spraying but the experts
say that even if spraying was done both inside and outside homes and was
100 percent effective (a very costly and labour intensive exercise) the
pesky eggs hatch the moment your back is turned, the next day.
way out is to interrupt the breeding by creating a zero tolerance of
mosquitoes which can only be done if all of us (some won’t do) in every
home interrupt the breeding. We do this through eternal vigilance:
cleaning our drains, covering our water, emptying every vessel, every tin
pan, drum, vase and pot of standing water. And every single home needs to
do it. If you do it, and I don’t, the damn things will still breed and
get into your house and vice versa.
we like it or not we are all in this together. United we stand, divided we
fall like flies. And I found that the clear water must be left standing
for at least a week before the female Aedes aegypti mosquito will breed in
it. I didn’t have to drain every drop from the glass before I went to
