Dengue cases spike in 2013



Dengue cases spike in 2013

Dengue cases have spiked in the first two months of this year. 

It's a cause for concern as the surge comes outside the traditional peak season. 

The situation is also aggravated by more people contracting the less common dengue strains in particular virus types 1 and 3. 

The National Environment Agency is concerned that people may have less immunity to these strains which could lead to an increase in dengue incidents. 

In Singapore, the most common strain is the dengue virus type 2. 

Just last month however, the type 2 strain accounted for just under 40% of all dengue cases. 

This is a big drop from June last year, when it accounted for about 85% of all cases.
