“…Few records exist of WNV in human samples [19–22], and in three pools of mosquitoes [19, 22]. In the State of Chihuahua, antibodies to West Nile have been isolated in samples of horses, goats, and several species of wild and poultry birds [7], and up to 5.13% in human samples in a cohort study [23] showing local transmission in Ciudad Juárez, Chihuahua. However, monitoring and surveillance of WNV in mosquitoes are almost non‐existent in Mexico.…”

“…Based on the recently documented epizootic [7] and the finding of WNV‐positive horses in Nuevo Casas Grandes Chihuahua, mosquitoes were collected from three areas of Chihuahua by entomological aspirators, traps for gravid females, CDC‐type traps, and manual larvae collection (Figure 1a,b). Having found that 43% of the pools were WNV‐positive indicates the susceptibility of mosquitoes to the virus and underlines the importance of protecting the biological material at the time of collection as well as the sensitivity of the qPCR in the laboratory.…”

“…vexans [5]. In Mexico, since the arrival of the WNV in the country, WNV-seropositive samples from non-human vertebrates (wild birds, horses, and bats) have been recorded mainly in the Yucatan Peninsula [12][13][14][15][16][17] and in the north of the country in samples of horses [18], dogs [6] and wild and domestic birds [7].…”

“…The vectorial capacity of other mosquito species with epidemiological and health implications due to their wide distribution and feeding preferences was similarly evaluated, among which Aedes vexans , Culiseta inornata , and Ochlerotatus dorsalis stand out. In Mexico, the presence of reservoirs of WNV in domestic dogs in Reynosa, Tamaulipas, a city in the North of the country has been verified [6], as well as in other vertebrates in different towns in Chihuahua [7]. However, there is a gap in the diagnosis and characterisation of West Nile cases in the human population of the sampled area, and no cases in field mosquitoes from the Mexican side of the border have been registered.…”

West Nile virus (WNV) has been documented in human and/or mosquito samples near the border with Mexico in El Paso, Texas, and Doña Ana County, New Mexico. However, on the Mexican side of the border, particularly in the State of Chihuahua, no such cases of WNV-infected mosquitoes have been documented. We tested 367 mosquitoes of four species (Culex quinquefasciatus, Cx. tarsalis, Aedes aegypti, and Aedes (Ochlerotatus) epactius) and found a high rate of WNV-positivity, including the first record of Ae. (Ochlerotatus) epactius infection with WNV. These results call for intensifying WNV surveillance efforts on the border between the United States and Mexico, with particular emphasis on vector control and monitoring of the species included in this study. K E Y W O R D S Aedes (Ochlerotatus) epactius, flavivirus, mosquito, vector-borne-disease, West Nile virus David Mejia Zuñiga and Jorge Cime-Castillo contributed equally.

“…An aliquot of each serum was transported to Iowa State University and serologically and antigenically tested for seven arboviruses known to occur in Guerrero (CHIKV, DENV1–4, WNV, and ZIKV). 3 – 5 To identify patients with acute CHIKV infections, sera were assayed for CHIKV IgM using the CHIKjj Detect IgM ELISA Kit (InBios International Inc., Seattle, WA). The laboratory criteria for the diagnosis of chikungunya, as established by the WHO, is the isolation of CHIKV from acute serum, detection of CHIKV IgM or RNA in acute serum or a 4-fold increase in CHIKV IgG titer in sera collected at least 3 weeks apart.…”

We provide evidence of concurrent and close sequential infections between SARS-CoV-2 and select arboviruses—namely, chikungunya virus (CHIKV); dengue viruses 1, 2, and 3 (DENV1–3), and Zika virus (ZIKV)—in patients in Guerrero, southwest Mexico, in 2020–2021. The study population consisted of 176 febrile patients with laboratory evidence of SARS-CoV-2 infection. Sera from all patients were serologically and antigenically tested for seven arboviruses known to occur in Guerrero. Eighteen patients contained CHIKV IgM, six of whom also contained CHIKV RNA. Another 16 patients contained flavivirus antigen. The flaviviruses responsible for the infections were identified by plaque reduction neutralization test as DENV1 (two patients), DENV2 (five patients), DENV3 (three patients), ZIKV (three patients), and an undetermined flavivirus (three patients). In summary, we identified patients in Guerrero, Mexico, with concurrent or recent sequential infections between SARS-CoV-2 and select arboviruses, exemplifying the importance of performing differential diagnosis in regions where these viruses cocirculate.

Over the last decade, there has been an increasing concern for epidemics in Latin America, as well as in other regions, due to arboviruses causing epidemics. Before 2013, dengue and yellow fever were of major preoccupation in urban and rural areas, respectively. But after that year, the emergence of chikungunya (2013) and Zika (2015) with their widespread in the region, affected millions of individuals, especially in tropical countries. Nowadays, other alpha and flaviviruses, but also bunyaviruses, have been circulating in the region causing small outbreaks, as is the case of Mayaro, Madariaga, Rocio, Oropouche, and St. Louis encephalitis, among others. In the current chapter, we address the situation regarding these other arboviruses that have been neglected by also being a differential diagnosis and an etiology of febrile syndrome in the region.
