The Seroprevalence of human brucellosis in Yemen was ranging from 0.3 to 32.3%. Nevertheless, it is suggested that a stronger inter-sectoral collaboration among pregnant women, veterinary, medical and public health professionals and country level in terms of one-health approach should be promoted. In spite of this disease is reported in humans and all domestic animals of the country, Yemeni people lack awareness about the zoonotic potential of the disease with their existing habit of raw milk consumption and close contact with domestic animals.

It also known as “Malta fever”, “undulant fever”, or “Mediterranean fever” [1]. Brucellosis caused by Brucella which is a small, gram-negative, coccobacilli, aerobic, facultative intracellular, non-motile, non-fermenting, non-spore- forming, non-fermenting [2,3]. Four species cause human disease: B. abortus in cattle and buffalo, B. canis in canine, B. suis in pigs, and B. melitensis in sheep, goats and camels which is the most virulent and the principle cause of human infection [1,4]. Brucella can be found in both domestic and wild animals. It is transmitted to humans through direct or indirect contact with infected animals or their products [1,5,6]. Portals of entry of the organism are the conjunctiva respiratory mucosa and damaged skin [7]. The transmission from person to person is uncommon, but the infection from human sources may occur in the following ways: a. Vertical transmission with placental circulation, breast feeding, blood transfusion, bone marrow transplantation the and sexual contact [8]. b. Brucellosis is endemic in the Middle East, south and central Asia, north and east Africa, Mediterranean countries of Europe, and central and South America. Worldwide, reported incidence of human brucellosis in endemic disease areas varies widely, from <0.01 to >200 per 100,000 population [5]. c. The incidence of human brucellosis in most countries is unknown and it has been estimated that the incidence may be 25 times higher than the reported incidence due to misdiagnosis and under-reporting [9]. In Yemen, there is a little information of animal and human brucellosis. The serological investigations and bacteriological isolations of Brucella carried on the country are very scarce. In spite the disease is reported in all domestic ruminants of the country, Yemeni people lack awareness about the zoonotic potential of the disease with their existing habit of raw milk consumption and close contact with domestic animals. Destruction of human and animals brucellosis by test-and-slaughter is impracticable in developing countries including Yemen because of limited resources to compensate farmers whose animals are slaughtered during such screening programs. Also, the national program is not available for prevention and control of brucellosis in the country. Only, there is one veterinary lab for animals which located in Sana’a. The main obstacles limiting the control of the disease are: security of the country, shortage of funds, laboratory facilities and trained manpower. So, this review article aims to describe an overview on brucellosis situation of the country and supports brucellosis interesting researchers to more understand the disease situation in the country. It also guides policy makers to draw sound decisions regarding brucellosis control policies. Human brucellosis in Yemen Until now, no attempts have been made of Brucella isolation, identification of genotypes and estimation of disease burden in human host in Yemen. The results of local prevalence studies done in human (Table 1) are summarized below. Epidemiology Studies on the prevalence of brucellosis in the general human population are limited in number. The Seroprevalence of human brucellosis in these studies was ranging from 0.3 to 32.3%. The first report was conducted a survey of Brucella antibodies among Yemeni blood donors. It investigated 1405 human serum samples using serum agglutination test (SAT) and revealed 0.4% positive. The prevalence founded from this study was in different
