“…In Iran, it is estimated that 5 to 10% of the annual GDP budget has been allocated to manage disasters (122). Following disasters so many risk factors in favor of the propagation of vectors and multiplication of reservoirs will be created, and as a result, epidemics of varying degrees of CL will occur (96,(123)(124)(125).…”

Iran has invariably been under the growing public health threat of cutaneous leishmaniasis (CL), a significant barrier to local development that hinders the prevention and control efforts toward eliminating the disease. So far, no comprehensive and in-depth epidemiological analysis of the CL situation has been carried out nationwide. This study aimed to employ advanced statistical models to analyze the data collected through the Center for Diseases Control and Prevention of Communicable Diseases during 1989–2020. However, we emphasized the current trends, 2013–2020, to study temporal and spatial CL patterns. In the country, the epidemiology of CL is incredibly intricate due to various factors. This fact indicates that the basic infrastructure, the preceding supports, and the implementation plan related to preventive and therapeutic measures need crucial support. The leishmaniasis situation analysis is consistent with desperate requirements for efficient information on the control program in the area. This review provides evidence of temporally regressive and spatially expanding incidence of CL with characteristic geographical patterns and disease hotspots, signifying an urgent need for comprehensive control strategies. This information could be a suitable model and practical experience in the Eastern Mediterranean Region, where over 80% of CL is reported.

“…The results demonstrated increases in the leishmaniases frequencies in post-disaster conditions, but not robustly, and the authors emphasized that the effects of NDs on leishmaniases needed more meticulous and comprehensive studies. 12 Several studies in Iran have stressed out the frequency of CL after NDs. A significant increase in the number of CL cases and creating new foci of transmission after the Bam Earthquake of 2003 has been indicated in a previous study in Iran.…”

“…During the past decades, the most frequent NDs in Iran were floods, earthquakes, and droughts. 11 Although there are several reports on the frequency of malaria and leishmaniases in postdisaster conditions of stricken areas of Iran, 8,12 the relationship between NDs and the incidents of these infections is not clearly understood. Due to the importance of cutaneous leishmaniasis (CL) and malaria and frequent NDs in Iran, the relationship between them should be evaluated.…”

Background/Objective: Natural disasters (NDs) are calamitous phenomena that can increase the risk of infections in disaster-affected regions. This study aimed to evaluate the frequency of malaria and cutaneous leishmaniasis (CL) before and after earthquakes, floods, and droughts during the past four decades in Iran. Methods: Malaria and CL data were obtained from the reports of the Ministry of Health and Medical Education in Iran for the years 1983 through 2017. The data of NDs were extracted from the Centre for Research on the Epidemiology of Disasters (CRED). Interrupted time series analysis with linear regression modeling was used to estimate time trends of mentioned diseases in pre- and post-disaster conditions. Results: For the periods preceding the disasters drought and flood, a decreasing time trend for malaria and CL was found over time. The time trend of malaria rate preceding the 1990 earthquake was stable, a downward trend was found after 1990 disaster until 1997 (β coefficient: −10.7; P = .001), and this declining trend was continued after 1997 disaster (β coefficient: −2.7; P = .001). The time trend of CL rate preceding the 1990 earthquake had a declining trend, an upward trend was found after 1990 earthquake until 1999 (β coefficient: +8.7; P = .293), and a slight upward trend had also appeared after 1999 earthquake (β coefficient: +0.75; P = .839). Conclusion: The results of the current study indicated the occurrence of earthquakes, floods, and droughts has no significant effect on the frequency of malaria and CL in Iran.

“…Disasters, including earthquakes, tsunamis, and floods provide numerous precipitating factors and in turn, prepare suitable breeding conditions for the propagation of vectors and spread of parasites to susceptible hosts [ 71 , 72 ]. Large epidemics describe the disease in greatly populated cities particularly peri-urban inhabitants and disaster-affected public, enhance significantly population motility, frequent wildlife, and animal foodstuffs, and zoonotic diseases between countryside and municipal communities[ 73 ].…”

Leishmaniasis is a disease of poverty that imposes a devastating medical, social, and economic burden on over 1 billion people nationwide. To date, no in-depth study to analyze the major global challenges and needs assessment has been carried out. This investigation aimed to explore a comprehensive narrative review of leishmaniasis’s main challenges and initially highlight obstacles that might impede the implementation of control measures. Also, we propose a specific list of priorities for needs assessment. The presence of socioeconomic factors, multiple clinical and epidemiological forms, various Leishmania species, the complexity of the life cycle, the absence of effective drugs and vaccines, and the lack of efficient vector and reservoir control make this organism unique and sophisticated in playing a tangled role to react tricky with its surrounding environments, despite extensive efforts and implementation of all-inclusive former control measures. These facts indicate that the previous strategic plans, financial support, and basic infrastructures connected to leishmaniasis surveillance are still insufficient. Strengthening the leishmaniasis framework in a context of accelerated programmatic action and intensification of cross-cutting activities along with other neglected tropical diseases (NTDs) is confidently expected to result in greater effectiveness, cost–benefit, and fruitful management. Sensitive diagnostics, effective therapeutics, and efficacious vaccines are vital to accelerating advancement toward elimination, and reducing morbidity/mortality and program costs. Collective actions devoted by all sectors and policy-makers can hopefully overcome technical and operational barriers to guarantee that effective and coordinated implementation plans are sustained to meet the road map for NTDs 2021- 2030 goals.
