    BACKGROUND: Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. Body mass index is a simple index of weight-for-height that is commonly used in classifying overweight and obesity in adult populations and individuals.
    OBJECTIVES: A study was conducted to screen the medical students of AIMST University for overweight/obesity using Body Mass Index(BMI) and to determine the prevalence among them.
    MATERIALS AND METHODS: This is an institution based cross sectional study was conducted among 290 medical students using a pre-tested questionnaire and measured their Body Mass Index (BMI). Data obtained was analyzed statistically by calculating proportions.
    RESULTS: Out of 290 students who participated in the study, 45.2% were males. In the study, 14.8% were found to be overweight (BMI 23-24.9 kg/m2); 13.7% of males and 15.7% of females. Pre-obese students (BMI 25-29kg/m2) accounted for 15.9% of the total (males 18.3% and females 13.8%). 5.2% were found to be obese (BMI > 30 kg/m2): males 9.2% and females 1.9%. Also 14.8% were found to be underweight (males 12.2% and females 17.0%). The study group consisted of 63.8% Indian, 32.4% Chinese and 3.8% Malay students.
    CONCLUSIONS: The study reveals that the prevalence of overweight and obesity among the medical students of AIMST University is on the high, which is comparable to the findings of earlier studies conducted in Malaysia, reinforcing the need to encourage healthy lifestyle, healthy food habits and a physically active daily routine, among the adolescents and youth of this country.

    Problem: The proliferation of information and communication technologies in India has enabled the emergence of health-related digital applications, from which important ethical issues arise.

    Approach: The Aadhaar identification system provides each resident in India with a 12-digit unique identification number, linked to demographic and biometric data. Identification by Aadhaar in welfare programmes has the important advantage of ensuring targeted benefits reach the intended recipients.

    Local setting: Some of the major issues faced by the public health sector in India are inadequate funding and inefficient utilization of the funds allocated. The enhancement of currently available digital health records will greatly increase the efficiency of the health care services.

    Relevant changes: The Aadhaar identification system has been linked to several health programmes since 2013. Success was achieved in a programme encouraging pregnant women to undergo delivery at a health facility, as use of Aadhaar number ensured that cash incentives reached the correct recipient. However, interruptions in the treatment of patients with tuberculosis and acquired immunodeficiency syndrome have been reported in other health programmes, due to patients fearing a breach of their confidentiality.

    Lessons learnt: Although the proposed merging of the Aadhaar identification system with digital health care records could enable greater efficiency in monitoring public health and welfare programmes, important ethical issues of privacy and data ownership and use must be considered. In joining the digital revolution, low- and middle-income countries must also develop strict legal regulation to protect data and avoid information technology companies exploiting such databases for profit.

    The SARS-CoV-2 virus has spread globally and has severely impacted public health and the economy. Hand hygiene, social distancing, and the usage of personal protective equipment are considered the most vital tools in controlling the primary transmission of the virus. Converging evidence indicated the presence of SARS-CoV-2 in wastewater and its persistence over several days, which may create secondary transmission of the virus via waterborne and wastewater pathways. Although, researchers have started focusing on this mode of virus transmission, limited knowledge and societal unawareness of the transmission through wastewater may lead to significant increases in the number of positive cases. To emphasize the severe issue of virus transmission through wastewater and create societal awareness, we present a state of the art critical review on transmission of SARS-CoV-2 in wastewater and the potential remedial strategies to effectively control the viral spread and safeguard society. For low-income countries with high population densities, it is suggested to identify the virus in large scale municipal wastewater plants before following up with one-to-one testing for effective control of the secondary transmission. Ultrafiltration is an effective method for wastewater treatment and usually more than 4 logs of virus removal are achieved while safeguarding good protein permeability. Decentralized wastewater treatment facilities using solar-assisted disinfestation methods are most economical and can be effectively used in hospitals, isolation wards, and medical centers for reducing the risk of transmission from high local concentration sites, especially in tropical countries with abundant solar energy. Disinfection with chlorine, sodium hypochlorite, benzalkonium chloride, and peracetic acid have shown potential in terms of virucidal properties. Biological wastewater treatment using micro-algae will be highly effective in removal of virus and can be incorporated into membrane bio-reaction to achieve excellent virus removal rate. Though promising results have been shown by initial research for inactivation of SARS-CoV-2 in wastewater using physical, chemical and biological based treatment methods, there is a pressing need for extensive investigation of COVID-19 specific disinfectants with appropriate concentrations, their environmental implications, and regular monitoring of transmission. Effective wastewater treatment methods with high virus removal capacity and low treatment costs should be selected to control the virus spread and safeguard society from this deadly virus.
