Unveiling malaria’s silent threat: A path to effective prevention in India

Malaria, primarily transmitted by Plasmodium parasite, continues to be a life-threatening disease, with Plasmodium falciparum and P. vivax being the most dangerous species for human health. It is imperative to acknowledge that in the Southeast Asian region, India accounts for 77% of the overall cases of malaria; making it the country with the highest incidence of malaria in Asia[1]. Thus, an improved cost-effective approach to reduce malaria transmission and promoting overall positive public health outcomes in India is an urgent need to move towards disease eradication. A recent study conducted by Ronald et al. in Uganda provides valuable insights into the factors governing prevalence of malaria in low socioeconomic countries. Importantly, the study highlighted a significant 17.6% disparity in malaria prevalence between children from low socioeconomic backgrounds and those from higher socioeconomic status families[2]. This socioeconomic divide is closely linked to parents' education, employment opportunities, and income levels which influence their ability to implement effective malarial prevention measures. The research findings underscore a positive impact of various preventive measures; indoor residual spraying (IRS) and the use of insecticide-treated mosquito bed nets (ITNs) to combat malaria prevalence among children. These interventions were associated with an impressive 18.4% (p=<0.001) decrease in the percentage of affected children and a 0.3 times lower risk of contracting malaria. Notably, IRS was found to significantly reduce malaria risk by lowering the vector density, resulting in households sprayed with IRS being 0.2 times less (p=0.011) susceptible to malaria infection. The study also shed light on the influence of different religious affiliations on malaria prevalence, revealing an 11.7% increase in malaria cases among children whose mothers identified as Catholic compared to those from Anglican families. These findings indicate a potential link between religious beliefs and malaria incidence, highlighting the need for in-depth studies within India's diverse religious communities to better understand the factors contributing to rising cases. In light of these research findings, it can be suggested that additional measures are required to protect vulnerable children from malaria. World Health Organization (WHO) has recommended the use of the RTS,S/AS01 (RTS,S) malaria vaccine[3]. When combined with ITNs and IRS, this vaccine holds promise as an effective strategy to combat malaria prevalence in low-resource countries globally, including India. The initiation of RTS,S vaccination initiatives represents a favourable initial stride, and as per WHO it has the potential to decrease severe illness in 30% of immunized children[4]. Importantly, it provides active immunity to children, which becomes increasingly crucial as passive immunity acquired from mother diminishes over time, especially beyond the breastfeeding age. In conclusion, the promotion of existing techniques such as ITNs and IRS, along with introduction of innovative solutions like the RTS,S malaria vaccine represents a vital approach to tackle rising malaria cases and high prevalence among low socioeconomic countries, including India and various African nations. Furthermore, exploration of the role of religious beliefs in driving malaria incidence may unveil novel avenues for malaria prevention tailored to diverse religious communities as it could act as a barrier in providing effective measures.
