    Burden of dengue, leishmaniasis and lymphatic filariasis in India and its states from 1990�2019: Analysis from the Global Burden of Disease study (GBD 2019)
    (Public Library of Science, 2023-10-18T00:00:00) Dutta, Omprokash; Prasanth, Ajay; Kumari, Ashu; Akanksha, Kumari; Deeba, Farah; Salam, Nasir
    Vector-borne diseases such as dengue, leishmaniasis, and lymphatic filariasis, constitute significant sources of illness, disability, and mortality among the poor and vulnerable in many countries around the world, including India. Based on the global burden of diseases, injuries, and risk factors study 2019, we analyse the burden of dengue, leishmaniasis, and lymphatic filariasis, in India from 1990 to 2019. Over this period, there was a reduction in the burden of lymphatic filariasis and leishmaniasis. Notably, dengue emerged as the most common vector-borne disease, exhibiting high fatality rate above 15 years of age and the highest DALY within 15�49 age group. Additionally, dengue cases surged substantially between 1990 and 2019. Leishmaniasis related mortality and DALY declined in the year 2019 compared to the year 1990, with high mortality and DALY in the 0-49-year-old age group. For lymphatic filariasis, DALY was more pronounce among those in the 15�49-year age group, which underwent reduction in 2019. Males had a higher burden in other vector-borne diseases than females, although females had a slightly elevated dengue burden. These findings highlight the evolving epidemiological trends related to vector-borne diseases in India, over the last three decades and underline the critical significance of sustained efforts for the elimination and control of vector-borne diseases. � 2023 Dutta et al.

    A meta-analysis on the prevalence of Taenia solium and Taenia saginata infections in India
    (Oxford University Press, 2023-04-20T00:00:00) Balodhi, Ashutosh; Jain, Khushi; Gupta, Palak; Deeba, Farah; Salam, Nasir
    Tapeworm infections in humans are considered to be a significant public health menace. Despite its public health importance, the data on tapeworm infection remains fragmented and underutilised. The present study reviews the overall burden and distribution of taeniasis and cysticercosis caused by Taenia solium and Taenia saginata in India by conducting a systematic review of the scientific literature based on Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Data from 19 eligible articles were analysed and the prevalence of T. solium�associated taeniasis/cysticercosis was found to be 11.06% (95% confidence interval [CI] 6.856 to 16.119) and the prevalence of T. saginata�associated taeniasis was found to be 4.7% (95% CI 3.301 to 6.301). This systematic review and meta-analysis provides a comprehensive analysis of the available literature on tapeworm infections and assesses the burden of Taenia infection from India, identifying areas of high prevalence requiring active surveillance and public health interventions. � The Author(s) 2023.

    Prevalence of Amoebiasis and Associated Complications in India: A Systematic Review
    (Springer Science and Business Media Deutschland GmbH, 2022-04-11T00:00:00) Gupta, Palak; Singh, Kiran Kumari; Balodhi, Ashutosh; Jain, Khushi; Deeba, Farah; Salam, Nasir
    Purpose: Intestinal protozoan parasites are responsible for diarrheal diseases causing significant morbidity and mortality. Entamoeba histolytica is the principle protozoan parasite associated with diarrheal infections. The infection is often associated with inaccessibility to clean drinking water and poor sanitary conditions in low- and middle-income countries including India. A comprehensive systematic review was performed to evaluate a reliable nationwide estimate for prevalence and geographic distribution of amoebiasis in India and the complications associated with it. Methods: We used the PRISMA guidelines to perform a systematic review and meta-analysis of articles published between the year 2001�2020. Two English language databases PubMed and Web of Science were searched to achieve relevant studies. Results: Initial searches resulted in 467 studies out of which 64 eligible articles involving data from 289,659 human subjects from 12 states and 4 union territories were included in the final analysis. Prevalence of amoebiasis ranged from 3-23% in asymptomatic population, 0.64�11% in symptomatic patients and 1�17.5% in HIV-infected patients. Highest prevalence was seen in Tamil Nadu, Andaman Nicobar Island and North East India. Extra intestinal invasion of Entamoeba histolytica leading to complications such as amoebic liver abscess, amoebic colitis, colonic perforation and ameboma were also reported. Such complications have the potential to increase healthcare burden and may prove to be fatal. Conclusion: Amoebiasis remains a significant public health issue in India responsible for diarrheal diseases causing significant morbidity and mortality. Entamoeba histolytica is the principle protozoan parasite associated with amoebiasis. Public health efforts should be directed towards its control and better diagnostic methods should be employed for distinguishing between pathogenic and non-pathogenic species of Entamoeba. � 2022, The Author(s) under exclusive licence to Witold Stefa?ski Institute of Parasitology, Polish Academy of Sciences.
