Infectious diseases — practice question

In 2015, the World Health Organization (WHO) issued the Global Technical Strategy for Malaria 2016-2030. This worldwide strategy, building on the 2008 Global Malaria Action Plan (GMAP), is intended to advance the control and elimination of malaria. Both the global strategy and GMAP are designed to lower: • the case incidence (the number of new cases each year) of malaria • the mortality rate (the number of deaths each year) from malaria.
