Neglected Tropical Diseases in Lebanon

Abstract

Introduction Neglected tropical diseases (NTDs) are highly endemic and distributed within the Middle East and North Africa (MENA) region, affecting an estimated 65 million people. Lebanon suffers from several NTDs as they are either endemic in the country or imported via expats residing in endemic regions, refugees, and foreign labor force. The Syrian crisis and the displacement of refugees to Lebanon have made the country the largest host of refugees per capita right after the Syrian crisis in 2011, peaking in the year of 2013. Additionally, foreign labor in Lebanon come from different countries in Africa and Asia that are endemic with certain NTDs. The Lebanese diaspora is approximately twice the number of those residing in the country and is distributed throughout the continents carrying the risk of importing new NTDs. Materials and Methods A descriptive study about the prevalence of NTDs in Lebanon, their distribution, and factors contributing to spread was performed. The Lebanese Ministry of Public Health (LMPH) database regarding reportable transmissible diseases was reviewed for reportable NTDs between 2002 and 2020 in relation to age, gender, prevalence, and geographical distribution. The medical literature was searched using several engines looking for all reports about NTDs in Lebanon, those relevant to regions hosting Lebanese diaspora, and countries where the refugees and migrant workers came from. Results Only leishmaniasis, leprosy , echinococcosis , schistosomiasis, and rabies are mandatorily reportable NTDs by the LMPH. Additionally, case reports about fasciolosis, ascaridiosis, and Dengue were reported from Lebanon. The presence of the Syrian refugees in the country affected the prevalence of leishmaniasis and rabies. The most prevalent NTD in Lebanon is cutaneous leishmaniasis. The Lebanese diaspora reside mainly in South America, Africa, and in some Arab states known to be endemic with certain NTDs. Conclusion Little information is known about NTDs in Lebanon. The country is at an increased risk of experiencing several new NTDs due to refugee influx, foreign labor, economic crisis, and ever-growing number of Lebanese seeking work opportunities abroad. More information is needed to assess the true burden of NTDs in Lebanon and the future steps to contain and mitigate their effects.

The Use of Water Filters to Prevent Contagious Skin Infections Amidst Refugee Camps: A Research Protocol

“…The escalating incidence of leprosy, a bacterial skin infection with an increased rate of "1.6 new cases per year" since 2012, is of particular concern [4]. A 2020 study proved that poor water, sanitation and hygiene (WASH) factors are associated with higher odds of leprosy [5].…”

Defining indicators for disease burden, health outcomes, policies and barriers and facilitators to health services for migrant populations in the Middle East and North African region: a protocol for a suite of systematic reviews

“…17 Similarly, high rates of hepatitis B and C have been found in newly arriving sub-Saharan migrants in Libya (23.4% and 31.2%, respectively), 18 and migration has been identified as partly explaining the slowing of the decline in TB and the reintroduction of malaria in the region, 19 20 as well as outbreaks of neglected tropical diseases such as leishmaniasis and cysticercosis/taeniasis in Lebanon. 21 …”
