Summary: Arbovirus infections are prevalent in Africa due to the lack of established epidemiological surveillance systems and accurate differential diagnosis. Studies indicate these infections are endemic in most African countries, highlighting the need for improved monitoring to enhance diagnostic accuracy. Healthcare providers should be informed about prevalent arboviral diseases to better identify and manage possible cases.

Summary: This study evaluated factors associated with deaths from chikungunya (CHIK) in Fortaleza, Brazil. The results showed that chronic kidney disease and previous heart disease, presence of fever, abdominal pain, apathy, dyspnea, and arthritis were significantly associated with death. Laboratory findings such as leukocytosis, leukopenia, thrombocytopenia, neutropenia, and lymphopenia were also linked to higher risk of death.

Summary: Testing blood donations for arboviruses in Brazil can contribute to public health, as the study found that transfusion recipients were likely exposed to Zika virus, chikungunya virus, and dengue virus viremic blood components during the study period.

Summary: In Fortaleza, Brazil, there was simultaneous circulation and co-infection of Zika virus (ZIKV), dengue virus (DENV), and chikungunya virus (CHIKV) in women after a Zika epidemic. Socioeconomic and environmental factors associated with arbovirus positivity included low socioeconomic class and the presence of a water box sealing in the household.

Summary: Dutch travellers to Suriname, especially tourists, are at substantial risk of DENV infection. The introduction of ZIKV and CHIKV in Suriname has also increased the risk of infection. The potential cross-reactivity and cross-protection of anti-DENV and -ZIKV antibodies should be further explored.

Summary: Guangdong is a high-risk area for dengue, with seasonal transmission mainly triggered by imported cases. The highest risk period for local outbreaks is from August to September, affecting young and middle-aged adults. Dengue virus serotype 1 (DENV 1) has been the dominant serotype, with an increasing tendency of DENV 2. Local outbreaks of DENV 3 are rare, and DENV 4 is only found in imported cases. Early detection, case management, and precise control strategies are key for preventing local dengue transmission.

Summary: The study found that both Zika virus and chikungunya virus mainly spread in northern Colombia over short distances. While there were similarities between the epidemics, Zika virus spread considerably faster than chikungunya virus.

Summary: This report presents the epidemiological indicators of Dengue, Zika, and Chikungunya in 19 municipalities of the Southwestern Region of Bahia, Brazil from 2010 to 2016. The analysis includes vector characteristics, Home Infestation Index, and characterization of human reported cases, with most municipalities showing high annual values of Home Infestation Index, indicating a warning situation. The data collected are believed to contribute to public health policies aimed at controlling future epidemics of these arboviruses.

Summary: In the study, the dengue vaccine showed a protective effect against Zika virus infection caused by dengue virus infection, but the protective effect against serologically suspected Zika was not significant. Similarly, after the Zika epidemic, dengue antibody titers increased, and the impact of the Zika epidemic on the infected population depended on their baseline dengue serostatus.

Summary: This study analyzed the epidemiological profile of DENV, CHIKV, and ZIKV in patients with suspected infection in Juazeiro do Norte, Brazil using serological and molecular tests. The results showed a higher prevalence of CHIKV antibodies compared to DENV antibodies, with mono-infection rates of 19.23% for ZIKV, 3.84% for CHIKV, and 1.09% for co-infection with ZIKV and CHIKV.

Summary: This study aimed to identify sociodemographic and environmental risk factors for the occurrence of Zika, dengue, and chikungunya in adolescents. The study found that adolescents with better socioeconomic conditions had a lower risk of infection. Additionally, a higher risk of arboviral diseases was associated with a high mosquito infestation index in the school's region. These findings can contribute to the implementation of control measures in population groups and priority locations.

Summary: This study utilized whole-genome sequencing to analyze the evolutionary patterns of multiple dengue virus serotypes circulating in Nicaragua from 2013 to 2016. The research revealed two co-circulating lineages of DENV-1 and a unique divergent lineage of DENV-2 with high epidemic potential emerged in 2015, driving an outbreak in 2016.
