In Asia, dengue virus (DENV), Zika virus (ZIKV), and chikungunya virus (CHIKV) infections pose significant public health threats, which could result in substantially increased morbidity and mortality rates. These viruses, collectively known as arboviruses, share similarities in their epidemiology, transmission, and clinical manifestations. They often cause mild, subtle, or nonspecific clinical symptoms, while also potentially leading to severe and life-threatening complications [1]. Their rapid transmission is primarily facilitated through mosquito bites, notably by Aedes aegypti and Ae.

Arboviral infections have hit South America heavily in the past decade, with the epidemic of Zika virus in 2015–16, and recurrent outbreaks of chikungunya and dengue, the latter of which is affecting Brazil with a particularly high number of cases this year. In addition, the region is now facing the re-emergence of another little-known arbovirus, Oropouche virus, on an unprecedented scale.

Abstract The Zika virus (ZIKV) epidemic in Latin America (2015-2016) has primarily been studied in urban centers, with less understanding of its impact on smaller rural communities. To address this gap, we analyzed ZIKV sero-epidemiology in six rural Ecuadorian communities (2018-2019) with varying access to a commercial hub. Seroprevalence ranged from 19% to 54% measured by NS1 blockade of binding ELISA. We observed a decline in ZIKV seroprevalence between 2018 and 2019 that was greater among younger populations, suggesting that the attack rates in the 2015-16 epidemic were significantly higher than our 2018 observations. These data indicate that the 2015-16 epidemic included significant transmission in rural and more remote settings. Our observations of high seroprevalence in our area of study highlights the importance of surveillance and research in rural areas lacking robust health systems to manage future Zika outbreaks and vaccine initiatives.

The Ile-de-France Region (IDFR), which is set to host the Paris 2024 Olympics, is experiencing a concerning rise in imported cases of chikungunya, Zika, and dengue arboviral diseases [1]. The escalating presence of the Aedes albopictus mosquito, a competent vector for these diseases in temperate climates, is a significant threat [1]. The first dengue outbreak in the IDFR last fall underscored the local vulnerability to this risk [1].

IntroductionAcute undifferentiated febrile illnesses (AUFIs) impose a large burden in the tropics. Understanding of AUFI’s epidemiology is limited. Insufficient diagnostic capacity hinders the detection of outbreaks. The lack of interconnection in healthcare systems hinders timely response. We describe a protocol to study the epidemiology and aetiologies of AUFI and pathogen discovery in strategic areas of Latin America (LA). Methods and analysisGlobal Infectious Diseases Network investigators comprising institutions in Colombia, Dominican Republic, México, Perú and the USA, developed a common cohort study protocol. The primary objective is to determine the aetiologies of AUFI at healthcare facilities in high-risk areas. Data collection and laboratory testing for viral, bacterial and parasitic agents are performed in rural and urban healthcare facilities and partner laboratories. Centralised laboratory and data management cores deploy diagnostic tests and data management tools. Subjects >6 years with fever for

Purpose of review Arbovirus infections are a challenge for immunocompromised hosts who travel to or live in endemic regions or who receive organs or tissues from donors who travel or live in such areas. This review addresses Dengue (DENV), Chikungunya (CHIKV), and Zika (ZIKV) infections in hematological patients, hematopoietic cell or solid organ transplant recipients, and people with HIV (PWH). Recent findings Transmission is mainly due through Aedes mosquito bite. DENV and ZIKV may also be transmitted through blood, tissues or donor grafts. Clinical manifestations are quite similar and diagnosis requires laboratory confirmation to provide appropriate management. The best diagnostic method is PCR since serology may present false negative results in immunocompromised patients, or cross-reactivity as in the case of DENV and ZIKV. There is no specific treatment for any of these infections. Summary Educational and preventive measures are the best strategy: vector control, knowledge of the vector\'s habits, protection against mosquito bites, avoiding travel to endemic areas or with a current epidemic, and avoiding nonvector transmission according to local recommendations for donor deferral. Vaccination, currently only available for DENV, has not yet been studied in immunocompromised patients and is not currently recommended.

The transmission of flaviviruses, such as dengue virus (DENV) and Zika virus (ZIKV), poses a significant threat to global public health. Zhang et al. recently showed that Rosenbergiella sp. YN46 (Rosenbergiella_YN46), a bacterium from the mosquito gut, inhibits flavivirus transmission and thus offers a potential biocontrol strategy with broad public health implications.
