Advice to schools in north Queensland
Schools are particularly at risk for rapid and widespread transmission of dengue through a community.
In a past outbreak in north Queensland, a school was found to be a significant source of dengue mosquito breeding. Many of the children and staff acquired dengue at school and then transmitted the virus to mosquitoes at home.
Young children infected with dengue face a lifetime of risk from developing dengue haemorrhagic fever if they are infected by a different type of dengue.
How to reduce the risk at schools
Check containers where mosquitoes breed
It is important to check school premises regularly for mosquito breeding sites, and:
-
throw out unused containers
-
tip out containers that can hold water and story in a dry place
-
clean out roof gutters.
Dengue mosquitoes breed in containers that hold water. The dengue mosquito does not breed in rivers, swamps, open drains, creeks or mangroves. These mosquitoes do not like to travel far from mosquito breeding sites. The best form of control is to get rid of dengue mosquito breeding sites. Dengue mosquitoes breed in containers that hold water, such as:
-
buckets
-
tyres – discarded with no rims
-
tarpaulins and black plastic
-
pot plant bases
-
vases
-
boats
-
tin cans and plastic containers
-
roof guttering
-
rainwater tanks with damaged or missing screens
-
water features – fountains, frog ponds and bird baths
-
fallen palm fronds
-
worm farm containers
-
hydroponic gardens
-
uncapped fence posts
-
bromeliads
-
striking containers (to grow plant cuttings)
-
coconut shells.
Fill drain sumps
Drain sump pits (eg. in driveways or large car parks) have proven to be a significant site for dengue mosquito breeding, because most of these pits hold water. This problem can be fixed by filling the lower part of the pits with concrete or sand, or by ensuring that pest controllers treat them during routine treatment of your school. Accumulated debris stops the flow and creates stagnant pools. You may consider putting a finer mesh over the grate to minimise litter entering the drain.
Drain sump pits can be a significant mosquito breeding site
Use temporary measures, eg. larvicide/insecticide, until sump pits are rectified/levelled.
Christmas break prevention
Schools in high-risk areas should consider routine application of residual insecticide during the Christmas break as a pre-emptive measure to minimise dengue risk in the new year.
Roof guttering should be cleared of debris before school returns.
Insect repellent
During outbreaks, parents should consider applying repellent to children. This is particularly important if the school is in a Dengue Watch Area (where dengue has occured in the last month).
