The World Health Organisation (WHO) has identified anti- malarial resistance in four countries of South East Asia and launched an emergency response to prevent resistant strains of the malarial parasites from spreading further.

On the occasion of World Malaria Day today, the WHO has also cited concerns over resistance emerging to insecticides which countries like India and sub-Saharan Africa are using to treat mosquito nets for the purpose of vector control. The advice for such countries is — develop new insecticides.
