Viral Haemorrhagic Fevers and Malaria Co-Infections Among Febrile Patients Seeking Health Care in Tanzania

“…Available statistics indicate that Buhigwe is among the districts with high malaria prevalence (24%) in Tanzania [14,37]. Moreover, a recent seroprevalence study has reported a 4.4% overall prevalence of VHF in the same district, the highest rate reported in Tanzania [4]. Co-infections due to malaria and either RVF or CCHF were most prevalent in Kinondoni district.…”

“…Co-infections due to malaria and either RVF or CCHF were most prevalent in Kinondoni district. The district is within the high malaria burden region [37] and a recent study has reported an overall prevalence of VHF of 2.8% [4].…”

“…Moreover, a recent study in Tanzania has reported the presence of immunoglobulin M (IgM) and IgG antibodies against to CCHF, EVD, MVD, RVF, and YF in 12.8% of the population across the country. The speci c disease estimated seroprevalence of CCHF, EVD, MVD, RFV and YF was 2.0%, 3.4%, 1.2%, 4.8%, and 1.4%, respectively [4].…”

“…Viral haemorrhagic fevers (VHF) have become more prevalent in Sub-Saharan Africa during recent years, causing either sporadic or largescale epidemics, thus posing signi cant risk to public health. The VHFs reported in Sub-Saharan Africa in recent years include Crimean-Congo haemorrhagic fever (CCHF), Ebola virus disease (EVD), Lassa fever (LF), Marburg virus disease (MVD), Rift Valley fever (RVF), and yellow fever (YF) [1][2][3][4]. On the other hand, malaria is among the most important mosquito-borne parasitic endemic disease in the region, accounting for 94% of the reported cases globally [5].…”
