'Fogging campaign paying off'

THE MINISTRY of Health, citing success in its mosquito eradication campaign,
is reporting a decline in the incidence of dengue fever.

A Government release said January witnessed a drastic decrease in the Aedes
aegypti
mosquito, which carries dengue.

The campaign was stepped up in October 1993 after an increase in the mosquito
population, with most reports being made from the Black Rock catchment area of
Brighton, and the Pine area. Prior to October, however, there had been
sporadic cases from as early as April, 1993.

By December 1993 the Queen Elizabeth Hospital had sent 497 samples of
suspected cases of dengue fever to the Caribbean Epidemiological Centre in
Trinidad for confirmation.


Out of these, 18 per cent tested positive for the type four while none was
diagnosed with the more dangerous dengue haemorrhagic fever.

The three-pronged eradication campaign comprises an island-wide fogging
exercise, with the main focus being areas where reports of greater mosquito
activity are most numerous.

Running in conjunction with the fogging exercise is an educational programme
utilising both radio and television.

Health inspectors have also been mobilised with an increase in home visits and
talks at schools, polyclinics and to youth groups, about the part they can
play in helping to eradicate the mosquito around the home.

The Ministry of Health said it was pleased with the decline in the mosquito
indices and reports of dengue fever, and acknowledged that this could not have
been achieved without the support of the general public.

This is much apparent since the fogging exercise only targets the adult
mosquito, with a four to five day span of effectiveness.

Public support is therefore critical to the eradication and control of the
earlier stages of mosquito development, and the public is being encouraged to
continue its efforts by maintaining clean surroundings and by checking and
properly disposing of objects outside and inside the home which may aid in the
mosquito breeding process, the release said.
