There are at least five common mosquito-borne viruses (MBVs) recorded in Egypt, including dengue virus (DENV), Rift Valley fever virus (RVFV), West Nile virus (WNV), Chikungunya virus, and Sindbis virus. Unexpected outbreaks caused by MBVs reflect the deficiencies of the MBV surveillance system in Egypt. This systematic review characterized the epidemiology of MBV prevalence in Egypt. Human, animal, and vector prevalence studies on MBVs in Egypt were retrieved from Web of Science, PubMed, and Bing Scholar, and 33 eligible studies were included for further analyses. The monophyletic characterization of the RVFV and WNV strains found in Egypt, which spans about half a century, suggests that both RVFV and WNV are widely transmitted in this nation. Moreover, the seropositive rates of DENV and WNV in hosts were on the rise in recent years, and spillover events of DENV and WNV to other countries from Egypt have been recorded. The common drawback for surveillance of MBVs in Egypt is the lack of seroprevalence studies on MBVs, especially in this century. It is necessary to evaluate endemic transmission risk, establish an early warning system for MBVs, and develop a sound joint system for medical care and public health for managing MBVs in Egypt.

“…Five years later, an outbreak occurred in humans residing in Dariot district, Asyut Governorate; however, it was rapidly contained after application of the appropriate control measures [ 14 ]. Recently, in 2017, up to 2500 human cases of DF disease were reported in the Red Sea Governorate [ 15 ] where A. aegypti was documented to be circulating [ 16 ].…”

Sero-epidemiological study on Dengue fever virus in humans and camels at Upper Egypt

2020

Background and Aim: Dengue fever (DF) is an important mosquito-borne viral zoonosis affecting over 100 countries worldwide and putting about 3.9 billion people at risk of infection. The disease has re-emerged in Egypt since 2011; however, there is a paucity of recent epidemiological data available. Therefore, in this study, we employed a cross-sectional study to determine DF prevalence in humans and camels in Asyut and Sohag Governorates, Egypt, during 2019. Materials and Methods: A total of 91 humans and a similar number of dromedary camels were utilized in this study. Sera were obtained and analyzed for the presence of specific antibodies against DF virus using enzyme-linked immunosorbent assay. Related epidemiological data affecting the disease spread in humans and camels were recorded and statistically analyzed. Results: The seroprevalence of DF in humans and camels was 12.09% and 3.3%, respectively. The disease varied significantly by the species examined as humans were found to be at a higher risk of acquiring the infection compared to camels. Nearly equal odds of exposure (odds ratio [OR]) were seen in the individuals with close contact with camels compared to those without; however, individuals exposed to mosquitoes were at approximately 3 times higher risk of infection (OR=2.95 [95% confidence interval [CI], 0.73-11.93]) compared to individuals who were not exposed to mosquitoes (OR=0.033 [95% CI, 0.084-1.37]). Interestingly, DF seropositivity in camels was significantly related to the presence or absence of symptoms within 2 weeks before sampling (p=0.02) where symptomatic animals had higher odds of exposure (OR=19.51 [95%, 0.97- 392.3]) compared to asymptomatic ones (OR=0.05 [95%, 0.002-1.03]). Conclusion: The current study reports the presence of specific antibodies against dengue virus (DENV) in humans residing within Asyut and Sohag Governorates, Egypt. Furthermore, it provides the first serological evidence of DENV circulation in camels which is alarming. A more comprehensive study is needed; however, this baseline investigation underscores the urgent need for increasing awareness among people residing in the area as well as application of the appropriate mosquito control measures to avoid further spread of the disease.

were selected for entomological surveys where dengue fever was anticipated to be occurred at November 2017. A total number of 469 houses were participates survived, positive adult houses were 20.47% (96/469), while positive larvae houses were 10.23 % (48/469). The stogmoyia indices for the parameters of house index (HI), container index (CI) and Breteau index (BI) were (10.2, 7.0 &16) respectively. The survey yielded a total number of immature stages of Aedes aegypti of 92.22% (960/1041), or 92.5 % (888/960) for larvae and 7.5% (72/960) for pupa. The immature stages of other species were recorded 7.78% (81/1041), Aedes detritus, Culex pipiens, Cx. antennatus and Cx. perexiguus and represented 86.42% (70/81) for larvae and 13.58% (11/81) for pupa. Adults Ae. aegypti were 20.36% (90/442), but adult mosquito of other species were 79.64% (352/442). Adults Ae. aegypti at Hurghada showed resistant to deltamethrin, cyflothrin and bendiocarb, and suggested resistance to lambda-cyhalothrin, but they were susceptible to malathion. At Safaga City showed resistant for bendiocarb and susceptible to cyflothrin. Larvae of Aedes aegypti at Hurghada City showed resistant to chlorpyrifos, but susceptible to temephos. Also, at Safaga City showed susceptible to temephos insecticide.

Two Cases of Dengue Fever Imported from Egypt to Russia, 2017

Abstract: In 2017, two cases of dengue fever were imported from Hurghada, Egypt, where dengue fever was not considered endemic, to Moscow. These cases show how emergence of dengue fever in popular resort regions on the coast of the Red Sea can spread infection to countries where it is not endemic.
