“…An increase in the abundance of mosquitoes during the July and August months has been reported in Pune, attributed to ideal mosquitogenic conditions. 15 Mutations in the viral proteins might enhance the transmission potential and contribute to the emergence of the virus. Earlier studies have shown that mutations in the E1 and E2 proteins, namely E1:A226V, E1:E211K/N/R, and E2:V264A, affect virus infectivity, dissemination, and transmission in vector mosquitoes.…”

A surge in chikungunya was observed during 2020‐21 in Pune district of Maharashtra, India. Whole genome sequencing and phylogenetic analysis of 21 samples/sequences revealed them as Indian ocean lineage of East Central South African genotype. Two distinct sequence clusters were found to circulate during 2020‐21; one with E1:K211E and E2:V264A mutations while the other had E1:I317V mutation along with E1:K211E and E2: V264A mutations. The former, the predominant cluster (n = 18), clustered with chikungunya virus (CHIKV) strains of pre 2014 period while the latter (n = 3) clustered with 2016−2018 period Indian strains. Though E1: A226V was not detected in any of the 21 sequences, several unique mutations were detected in the strains which might have played key roles in the enhanced virus transmission during the period. The study highlights parallel evolution, introduction from the neighboring regions and cocirculation of two sequence clusters of CHIKV in Pune. The complete genome data can be useful to determine how the circulating strains differ from candidate vaccines and might help to predict the protective efficacy of chikungunya vaccine candidates.

“…Dengue control in India is based on vector control practices such as indoor space spraying, fogging, environmental management and promotion of personal protection (NVBDCP, 2014). However, the nation-wide distribution of dengue vectors in India is not known and the presence of aedine species has been established only in some parts of the country based on local vector surveillance such as in southern peninsular India (Selvan et al, 2016), North eastern states (Soni et al, 2018) as well as the western and eastern coastlines (Chatterjee et al, 2015;Shil et al, 2018). Moreover, climate change could significantly affect the known distribution of vectors.…”

Dengue is the most widespread arthropod-borne disease, that has become endemic in more than 100 countries (World Health Organization, 2020). It is usually found in tropical and sub-tropical climates, with a vast majority of dengue cases occurring in the Americas and in South-East Asia (World Health Organization, 2020). In India, dengue has witnessed an alarming upsurge in the past decade, with more than fivefold increase from 28,066 cases in 2010 (NVBDCP, 2010) to 157,315 cases in 2019 (NVBDCP, 2020).The two arthropod vectors of dengue are Aedes (Stegomyia) aegypti (L.) and Aedes (Stegomyia) albopictus (Skuse), which are also responsible for the transmission of several other arboviruses such as the chikungunya virus, yellow fever virus and Zika virus. Aedes aegypti exhibits an indoor resting behavior and primarily feeds on humans during the day (Scott & Takken, 2012). It is mostly found in urban areas and usually breeds in man-made water receptacles such as plastic containers and rubber tyres (Vijayakumar et al., 2014). Aedes albopictus prefers to rest outdoors and is an opportunistic feeder (Paupy et al., 2009), though strong anthropophagic behavior has also been observed in some studies (Delatte et al., 2010;Ponlawat & Harrington, 2005). The presence and population size of these arthropod vectors is highly dependent on climatic factors such as temperature, rainfall and relative humidity. The poikilothermic physiology of mosquitoes renders them sensitive to temperature extremities, which affects larval development as well as vector mortality (Farjana et al., 2012). Rainfall also supports vector populations by providing suitable habitat for development of the aquatic larval stages (Farjana et al., 2012).
