伊蚊传播的病毒性疾病，主要是黄热病 (YF)、登革热 (DEN)、寨卡 (ZIK) 和基孔肯雅热 (CHK)，导致世界各地（尤其是非洲）许多人死亡。这些疾病在西非曾爆发过大规模疫情。尽管多年来加纳曾发生过黄热病疫情，但尚未有 DEN、ZIK 和 CHK 疫情记录。然而，由于靠近最近爆发疫情的西非国家，疫情爆发的风险很高。这项研究调查了加纳北部拉拉班加和鼹鼠禁猎区的蚊子群，以评估黄热病 (YFV)、登革热 (DENV)、基孔肯雅热 (CHKV) 和寨卡 (ZIKV) 病毒的传播风险。从拉拉班加和鼹鼠野生动物保护区收集了未成熟和成年阶段的伊蚊。雨季收集的蚊子数量显着高于旱季（P>0.001）。雨季共采集伊蚊1930只，并进行形态学鉴定。其中，埃及伊蚊 1,915 只（99.22%），斑纹伊蚊 15 只（0.22%）。旱季期间，27 Ae。收集了埃及蚊子。总共 415 Ae。埃及伊蚊被分子鉴定为亚种水平，其中伊蚊。 (Ae) 埃及伊蚊是主要亚种。两个都是艾。埃及伊蚊和台湾伊蚊在该地区共生。通过 RT-PCR 检查，所有伊蚊群 (75) 的 DENV、ZIKV 和 CHKV 均为阴性。评估了三个幼虫指数，即房屋指数 HI（伊蚊幼虫或蛹呈阳性的房屋百分比）、容器指数 CI（伊蚊幼虫或蛹呈阳性的容器百分比）和 Breteau 指数 BI（每 100 所检查房屋中的阳性容器数量），作为研究区域传播风险的衡量标准。两个站点的 HI、CI 和 BI 如下：鼹鼠野生动物保护区（HI，42.1%，CI，23.5%和BI，雨季为100，旱季所有指数为0）和拉拉班加（雨季为39%、15.5%和61，旱季为2.3%、1.3%和2.3）。两个地区伊蚊孳生地的空间分布表明，伊蚊幼虫在距离人类较近的地区孳生。卡车轮胎是所有研究区域伊蚊幼虫的主要来源。需要有关伊蚊的物种组成和在其传播的疾病未来爆发中的潜在作用的信息，以设计有效的监测和病媒控制工具。
Aedes-borne viral diseases mainly Yellow Fever (YF), Dengue (DEN), Zika (ZIK) and Chikungunya (CHK) have contributed to many deaths’ in the world especially in Africa. There have been major outbreaks of these diseases in West Africa. Although, YF outbreaks have occurred in Ghana over the years, no outbreak of DEN, ZIK and CHK has been recorded. However, the risk of outbreak is high due to its proximity to West African countries where outbreaks have been recently been recorded. This study surveyed the mosquito fauna to assess the risk of transmission of Yellow fever (YFV), Dengue (DENV), Chikungunya (CHKV) and Zika (ZIKV) viruses in Larabanga and Mole Game Reserve areas in Northern Ghana. The immature and adult stages of Aedes mosquitoes were collected from Larabanga and Mole Game Reserve area. There was a significant (P>0.001) number of mosquitoes collected during the rainy season than the dry season. A total of 1,930 Aedes mosquitoes were collected during the rainy season and morphologically identified. Of these, 1,915 (99.22%) were Aedes aegypti and 15 (0.22%) were Aedes vittatus. During the dry season, 27 Ae. aegypti mosquitoes were collected. A total of 415 Ae. aegypti mosquitoes were molecularly identified to subspecies level of which Ae. (Ae) aegypti aegypti was the predominant subspecies. Both Ae. aegypti aegypti and Ae aegypti formosus exist in sympatry in the area. All Aedes pools (75) were negative for DENV, ZIKV and CHKV when examined by RT- PCR. Three Larval indices namely House Index, HI (percentage of houses positive for Aedes larvae or pupae), Container Index, CI (the percentage of containers positive for Aedes larvae or pupae) and Breteau Index, BI (number of positive containers per 100 houses inspected) were assessed as a measure for risk of transmission in the study area. The HI, CI and BI for both sites were as follows; Mole Game Reserve (HI, 42.1%, CI, 23.5% and BI, 100 for rainy season and 0 for all indices for dry season) and Larabanga (39%, 15.5% and 61 for rainy season and 2.3%, 1.3% and 2.3 for dry season). The spatial distribution of Aedes breeding sites in both areas indicated that Aedes larvae were breeding in areas with close proximity to humans. Lorry tires were the main source of Aedes larvae in all the study areas. Information about the species composition and the potential role of Aedes mosquitoes in future outbreaks of the diseases that they transmit is needed to design efficient surveillance and vector control tools.
