World Health Organization and Bureau of Indian Standards recommend zero tolerance for coliforms in drinking water. A total of 592 drinking sources from 11 districts of Himachal Pradesh, India, were screened for coliform contamination and the presence of fecal origin Escherichia coli. The study revealed contamination levels of 55.

Objective: Informal healthcare providers (IHCPs) play a big role in health systems in low-and middle-income countries (LMICs) and are often the first point of contact for healthcare in rural and underserved areas where formal healthcare infrastructure is insufficient or absent. This study was performed to systematically review the literature on interventions targeting IHCPs in improving the delivery of healthcare services in LMICs.

Methods: PubMed, Embase, and Cochrane CENTRAL databases were searched for studies that assessed any type of intervention among IHCPs to improve the delivery of healthcare services in any LMIC.

Introduction: Post-COVID-19 condition (post COVID, also known as long COVID) is a global public health issue estimated to affect over 100 million people. Common symptoms include fatigue, dyspnoea and cognitive dysfunction ('brain fog'). Over time, these symptoms have an adverse effect on mental health, physical activity and quality of life (QoL).

Introduction: Rotavirus-induced viral gastroenteritis outbreaks result in over two million hospitalizations globally yearly. Wastewater-based epidemiology (WBE) has emerged as a crucial tool for detecting and monitoring viral outbreaks. The adoption of WBE has been instrumental in the early detection and surveillance of such viral outbreaks, providing a non-invasive method to assess public health.

Aim: To evaluate and compare the effect of impregnated retraction cord vs Laser on gingival attachment level and pain perception following retraction for subgingival margins.

Settings And Design: Many methods for achieving and measuring the amount of gingival retraction in fixed prosthodontic work have been advocated. Though the gingival attachment level is crucial in Periodontology, the literature available regarding the effect of these retraction methods on the same is scarce.

Background: Infections caused by soil-transmitted helminths (STHs) are the most prevalent neglected tropical diseases and result in a major disease burden in low- and middle-income countries, especially in school-aged children. Improved diagnostic methods, especially for light intensity infections, are needed for efficient, control and elimination of STHs as a public health problem, as well as STH management. Image-based artificial intelligence (AI) has shown promise for STH detection in digitized stool samples.

Article Synopsis
  • India launched its COVID-19 vaccination drive on January 16, 2021, focusing on adults over 18, leading to over 1 billion first doses and nearly 950 million second doses, but only 217 million precaution doses were administered, indicating a significant gap.
  • The Ministry of Health & Family Welfare conducted an exploratory study across six states to identify the facilitators and barriers affecting the uptake of precaution doses among adults, utilizing in-depth interviews and focus group discussions among various community members and health officials.
  • Preliminary results suggested that an increase in COVID-19 cases motivated some community members to pursue precaution doses, highlighting the need for improved communication and outreach in future immunization campaigns.

Waste segregation at source, particularly at the household level, is an integral component of sustainable solid waste management, which is a critical public health issue. Although multiple interventions have been published, often with contradictory findings, few authors have conducted a comprehensive systematic synthesis of the published literature. Therefore, we undertook a systematic review to synthesize all published interventions conducted in any country in the world which targeted household-level waste segregation with or without additional focus on recycling or composting.

Introduction: A neurodevelopmental disorder, autism is typically identified with three primary behavioral consequences, such as social impairment, communication problems, and limited or stereotypical behavior. Because of its co-morbidity and lack of therapeutic options, autism is a global economic burden. A short chain of fatty acid, propionic acid is formed biologically by the gut microbiome.

Introduction: Crowdsourcing is an emerging technique to engage or access a wider set of experts and multiple stakeholders through online platforms, which might effectively be employed in waste management. Therefore, we assessed the feasibility of the crowdsourcing method to provide an alternative approach that can improve household waste segregation using an "online-slogan-contest".

Methods: The contest was promoted via targeted emails to various governmental and non-governmental organizations and through social media platforms for around 4 weeks (25 days).

Waste segregation is an essential function in improving waste management. Waste segregation not only facilitates recycling and reduces waste going to landfills, rather it can benefit our environment and human in various ways. A pick analysis of waste composition is used to characterize the household waste stream and thus can analyze the segregation rate among the residents.

Introduction: Individual and community characteristics predictive of knowledge, perception, and attitude on COVID-19, specifically on gender, have not been adequately explored.

Objective: To examine the gender differences in COVID-19 knowledge, self-risk perception and public stigma among the general community and to understand other socio-demographic factors which were predictive of them.

Method: A nationally representative cross-sectional multi-centric survey was conducted among adult individuals(≥18 yrs) from the community member (N = 1978) from six states and one union territory of India between August 2020 to February 2021.

Background: The health implications surrounding a mass gathering pose significant challenges to public health officials. The use of syndromic surveillance provides an ideal method for achieving the public health goals and objectives at such events. In the absence of published reports of systematic documentation of public health preparedness in mass gatherings in the local context, we describe the public health preparedness and demonstrate the operational feasibility of a tablet-based participatory syndromic surveillance among pilgrims during the annual ritual circumambulation- .

Widespread use of antibiotics for treating human and animal ailments has increased their discharge in the environment through excreta. Moreover, unscientific disposal of unused antibiotics has further increased their presence in the environmental matrices. Thus, occurrence of used and/or discarded antibiotics in water resources is becoming a growing concern across the globe.
