A retrospective study on imported malaria in Jordan. 2. Malaria among non-military Jordanians

Current Status and the Epidemiology of Malaria in the Middle East Region and Beyond

Vector-borne parasitic infectious diseases are important causes of morbidity and mortality globally. Malaria is one of the most common vector-borne parasitic infection and is caused by five Plasmodium species, namely P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi. Epidemiologically, differences in the patterns of malaria cases, causative agent, disease severity, antimicrobial resistance, and mortality exist across diverse geographical regions. The world witnessed 229 million malaria cases which resulted in 409,000 deaths in 2019 alone. Although malaria cases are reported from 87 countries globally, Africa bears the brunt of these infections and deaths as nearly 94% of total malaria cases and deaths occur in this continent, particularly in sub-Saharan Africa. Most of the Middle East Region countries are malaria-free as no indigenous cases of infection have been described in recent years. However, imported cases of malaria continue to occur as some of these countries. Indeed, the six Gulf Cooperation Council (GCC) countries have large expatriate population originating from malaria endemic countries. In this review, the current status and epidemiology of malaria in the Middle East Region countries and other malaria-endemic countries that are home to a large migrant workforce being employed in Middle East Region countries are discussed.

The Double-Edged Sword of Military Response to Societal Disruptions: A Systematic Review of the Evidence for Military Personnel as Pathogen Transmitters

Given their lack of immunity and increased exposure, military personnel have the potential to serve as carriers or reservoirs for infectious diseases into or out of the deployment areas, but, to our knowledge, the historical evidence for such transmission events has not previously been reviewed. Using PubMed, we performed a systematic review of published literature between 1955 and 2018, which documented evidence for military personnel transporting infectious pathogens into or out of deployment areas. Of the 439 articles screened, 67 were included for final qualitative and quantitative review. The data extracted from these articles described numerous instances in which thousands of military service members demonstrated potential or actual transmission and transportation of multiple diverse pathogens. These data underscore the immense importance preventive medical professionals play in mitigating such risk, how their public health efforts must be supported, and the importance of surveillance in protecting both military and civilian populations.

Preparedness against self-infection and importation of Malaria - An airport survey among Saudis traveling to endemic countries

Background:

Infected travelers returning from malaria endemic countries pose the threat of local outbreaks in nonendemic countries. Such outbreaks are becoming potential public health threats with increasing volume of international travels.

Aims:

This study aimed to assess the knowledge, attitude, and practices toward malaria, its prevention and treatment among Saudi air travelers visiting malaria-endemic countries.

Methods:

A cross-sectional survey was conducted among Saudi passengers who were waiting at the departure gates of the King Khalid International Airport, Riyadh to travel to five chosen malaria-endemic countries. Knowledge, attitude, practice, and health-seeking behavior for malaria were assessed using a self-administered questionnaire. Factors associated with favorable responses were identified by statistical tests.

Results:

Among 531 travelers, adequate knowledge, favorable attitude, and healthy practices pertaining to malaria were present in 42.7%, 80.2%, and 55.7%, respectively. Traveling to India, age >=30 years, tourists and traveling businessmen, previous visit to same country or region, seeking malaria-specific advice were significantly associated with adequate knowledge. Only 11.3% had sought pretravel health advice on malaria. Lack of knowledge about the existence and importance of pretravel consultation was the common reason for not seeking advice.

Conclusion:

Knowledge about malaria and practice of preventive measures were suboptimal among Saudi travelers. Public awareness about travel consultation and chemoprophylaxis should be a part of malaria elimination and prevention efforts. Primary care physicians should take into account the level of knowledge among prospective travelers and provide opportunistic travel health services or refer them appropriately.
