Anyways I had a look at the dengue data of Singapore (the
published ones). You really cannot expect much from the Government
now . They are already reacting to it - the wheels are in motion
.
For those of you not familiar with study of diseases, the
epidemiological triad comes into play - environment, host ,
agent.
The dengue (agent) epidemic is based on the Aedes Aegypti mosquito
vector. Singapore's high density population and living conditions
does not make it easier to control dengue. Dengue can also be
imported easily, if you look at how busy Changi Airport,causeway
and shipping ports. Environment, host and agents - Singapore has
all the essential ingredients for a huge epidemic, not only Dengue
(aka Flaviviruses) but also for influenza and SARS.
You can't shut down the airport,causeway or ports because it
affects the economic structure of the country. You can't create a
no entry zone around them because Singapore is too small and land
is scarce. You can't fog the whole Singapore at all.
What they can only do is educate the public and hope it that the
public listens- that is the cheapest form . The other alternative
is to start active sentinel surveillance which is too expensive.
Not sure if they use spatial syndromic surveillance. I know that
research is going on in that aspect in USA and Australia - tag
certain group of symptoms and track it all out.
So really , I think effectiveness is majorly based on the
grassroots response - whether they want to listen or not .
Threatening them with legal repercussions under the 1998 Control of
Vectors and Pesticide Act doesn't help at all. The kiasee attitude will kick in as an
advantage when everyone finally realises the impact. The case of
SARs is one fine example.
Dengue and any communicable diseases can only be controlled
effectively if all parties working together - not against each
other ( or resentfully silent against the other). Now is not the
time for complaining, it is more the time of working together.
Complain later.
