Re: Singapore MOH Updates

RoRo,

Have you taken a plot over time on the conjunctivitis cases?

[Ronan Kelly]

Re: Singapore MOH Updates

Hi NS1,

Singapore MOH has a graph of conjunctivitis incidence for 2009 and 2010 on page 8 of this link; http://www.moh.gov.sg/mohcorp/upload...10_week_50.pdf

They also provide graphics for most of the other reportable diseases.
