Singapore : Weekly dengue cases hit new high

Via Channel News Asia, Singapore dengue cases are up :

" Weekly dengue cases so far this year have hit a new high, with 185 cases recorded in the 26 June-2 July period.

The number exceeded the Ministry of Health's (MOH) warning levels of 146 cases per week for the first time this year.

And if dengue cases increase to 191 per week, it would take the situation to epidemic levels.

The National Environment Agency (NEA) said that last week's 185 cases were also higher than the average 66 cases a week recorded in May and 108 cases a week recorded in June last year.

The NEA said dengue cases have been creeping up, with the weekly average number of cases increasing from 106 in May to 149 last month. But it said this is still far from the 2005 dengue outbreak situation.

The NEA said these levels are moving averages based largely on the past five years worth of data.

As such, the higher the previous cases recorded, the higher the warning and epidemic level would be.

The NEA said given that dengue cases have been relatively low in the past years since the 2005 outbreak, this year's warning and epidemic levels are at the lower end.

In 2006, the warning and epidemic levels were higher, at 256 cases per week and 378 per week, respectively, because of the high cases in 2004 and 2005."
