Effective monitoring, epidemiological assessment and evaluation are necessary to achieve the aim of interrupting LF transmission. This manual is designed to ensure that national elimination programmes have available the best information on methodologies and procedures for monitoring MDA, appropriate...ly assessing when infection has been reduced to levels where transmission is likely no longer sustainable, implementing adequate surveillance after MDA has ceased to determine whether recrudescence has occurred, and preparing for verification of the absence of transmission. The manual provides general guidance to national programmes; relevant background information on technical issues is contained in the annexes. As real-life situations may not correspond to predefined categories, consultation with WHO and experts is recommended in complicated situations.

                                                                Asthma is one of the most common chronic respiratory conditions in the world and is increasing in prevalence, particularly in Africa and other low-income countries. The disproportionately high numbers of premature deaths and severe or uncontrolled cases in many African countries are indicative of th...eir inability to cope with a costly disease like asthma. Progress has, however, been made in understanding the complex and heterogeneous nature of the disease. The objective of this study will be to summarise the epidemiological literature on the nature of asthma in African countries.
