Background: Lymphatic filariasis (LF) is a mosquito-borne parasitic disease which is targeted for elimination as a public health problem worldwide. Niue is a small self-governing South Pacific island nation with approximately 1600 residents that was formerly LF endemic. Here, we review the progress made towards eliminating LF in Niue since 1999., Methods: This study has reviewed all the available literature relating to LF in Niue to assess surveillance efforts and the elimination of transmission. Reviewed documentation included both published and unpublished works including historical reports of LF, WHO PacELF records, and Niue Country Reports of the national LF elimination program., Findings: Niue conducted mapping of baseline LF endemicity by testing the total present and consenting population for LF antigen with immunochromatographic test (ICT) in 1999, when circulating filarial antigen prevalence was 3.1% (n = 1794). Five nationwide annual mass drug administration (MDA) rounds with albendazole (400 mg) and diethylcarbamazine citrate (DEC) were undertaken from 2000 to 2004, with coverage reported from distribution records ranging from 78 to 99% of the eligible population, which excluded pregnant women and children under 2 years of age. A further whole population survey using ICT in 2001 found 1.3% positive (n = 1630). In 2004, antigen prevalence had reduced to 0.2% (n = 1285). A similar post-MDA survey in 2009 indicated antigen prevalence to be 0.5% (n = 1378). Seven positive cases were re-tested and re-treated every six months until negative., Conclusions: After five rounds of MDA, Niue had reduced the LF antigen population prevalence in all ages from 3.1% to below 1% and maintained this prevalence for a further  five years. Due to Niue's small population, surveillance was done by whole population surveys. Niue's results support the WHO recommended strategy that five to six rounds of annual MDA with effective population coverage can successfully interrupt the transmission of LF. Niue received official acknowledgement of the validation of elimination of LF as a public health problem by the WHO Director-General and WHO Western Pacific Regional Office (WPRO) Regional Director at the 67th session of the Regional Committee for the Western Pacific held in Manila in October 2016., Competing Interests: The authors alone are responsible for the views expressed in this article and they do not necessarily represent the views, decisions or policies of the institutions with which they are affiliated.This was a secondary data analysis reviewing de-identified data.Manuscript does not contain data from any individually identifiable person.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Objectives: We conducted a survey of health facilities and household members to determine supply and demand aspects of contraceptive use in Azerbaijan., Methods: In June 2005, we conducted interviews with 758 women and 253 men in a community-based survey in 40 communities in five districts. We also surveyed a sample of health facilities and pharmacies and conducted interviews with key informants., Results: Both men and women in these communities desire small families, yet significant supply and demand impediments exist. Despite community interest, lack of knowledge of contraception is prevalent. Fear of side effects plays a role in non-use and discontinuation of modern methods, although little opportunity exists for counselling on side effects, since few health workers are trained. An obstacle to use is legislation that only allows contraception to be prescribed by gynaecologists, who are mostly concentrated in the hospitals of urban centres. However, the main handicap to increased use of modern contraception, is insufficient contraceptive supply. Not only is there a lack of method choice nationally, but few of the facilities we surveyed had any contraceptives available. This situation threatens to worsen as the United Nations Population Fund (UNFPA) retracts commodities' funding., Conclusions: The lack of knowledge of modern contraception, lack of trained staff and poor commodity availability signals that much remains to be done for the people of Azerbaijan to achieve their fertility control goals.
