Journal Title: Asian Pacific Journal of Tropical Medicine - Year 2018, Vol 11, Issue 10
Abstract
All over the world approximately 98 countries faces endemic outbreak of leishmaniases, which is a group of parasitic disease. More than 350 million people reside under the risk of these diseases and new cases per year is about 0.7 to 1.3 million. The culprit and contagious agent Leishmania donovani (L. donovani), which is responsible for leishmaniases are breed mainly in South Asian constituency that harbor’s mainly the visceral leishmaniases (VL) globally. The inter-relationship within main etiological factor (L. donovani & remaining species of leishmaniases) and resultant biological events has been confronted in past years. For this reason there have been accentuated condition of reconsidering the formerly categorization. Rendering to the latest WHO data published in 2017 about leishmaniases death in bangladesh grasped to 988 or 0.13% of total mortality. The age of mortality rate is 0.61 per 100 000 of population, that ranks 7th in whole over the world. This disease can present mainly by three forms: cutaneous, mucocutaneous, and VL. Skin ulcer is the main presentation of cutaneous form, where in the mucocutaneous types, it present with skin ulcer with pyrexia, reduced RBC, hepatomegaly and splenomegaly. Whereas, VL well known as Kala-a-zar, which is focal, huddled inside the households, as well as typically cope the poor people. Also, VL stretches the poverty episode; nevertheless, loss of throughput and highly expensive treatment policy for affected families. Etiological factors for infectivity including residing area within 50 m fom the infected area or home as well as malnutrition and household ailments including splintered mud wall. Though the vector control is essential requirement for disease abolition, but there has been a noticeable lack of innovations from many years back. In addition, there have been many sorts of remarkable improvement in the field of diagnosis of disease as well as therapeutic intervention and vaccination protocol development. But also many kinds of obstacles arise. For exclusion of L. donovani induced leishmaniasis from the certain region of our country become a challenge, and the reality is an effective amendment of existing and new tools will be essential requirements. Both strong political and active community participation would be imperative, also need inter-country cooperation and mutual partnerships. Furthermore, appropriate diagnostic tools, treatment policies including effective demographic surveillance mandatory for ensure of successful outcome to elimination of L. donovani. Considerable success of operational research activities in early detection of disease and complete treatment, IVM, and clinical research achieved from National L. donovani elimination program. Though the activities need to strengthen their policies fro effective surveillance, behavioral change communication (BCC), monitoring, and evaluation as a whole. The main obstacles for the elimination program are inadequate human sources, funds, and logistics. These constrains may overcome by build up good communication and partnership with national and international organizations, donor agencies, and sponsorship institutions. Also operating wisely and diligently with policy makers to warrant this efficious platform is bearable.
