We have discovered early markers for prognosis of development of severe Dengue. The findings were recently published in the Journal of Biomedical Science and Biomed Research International. Only a small percentage of dengue infected patients develop severe symptoms.

However, there is no way to predict who will develop severe symptoms among dengue patients during their admission to hospitals.The discovered method will predict who will develop severe dengue before any severe symptoms appear. Therefore, hospital care can be provided to those patients who may develop severe symptoms to reduce mortality.

Due to this discovery, monitoring all dengue patients with hospital care will not be necessary. This will relieve the burden of hospital care. We are currently in the process of developing economic methods for prognosis of severe dengue that can be used in resource limited settings based on these markers.

These studies are supported by the UNESCO and the International Development Research Center, Ottawa, Canada under the Early Career Research Fellowship Grant awarded by the Organization for Women in Science for the Developing World (OWSD), the National Science Foundation, Sri Lanka and the University of Kelaniya.
