Molecular Characterization and Genomic Surveillance of SARS-CoV-2 Lineages in Central India.

Since the first reported case of COVID-19 in December 2019, several SARS-CoV-2 variants have evolved, and some of them have shown higher transmissibility, becoming the prevalent strains. Genomic epidemiological investigations into strains from different time points, including the early stages of the pandemic, are very crucial for understanding the evolution and transmission patterns. Using whole-genome sequences, our study describes the early landscape of SARS-CoV-2 variants in central India retrospectively (including the first known occurrence of SARS-CoV-2 in Madhya Pradesh).

Use of dry blots for serotyping and genotyping of dengue viruses: A pilot study.

Background & Objectives: Dengue (DEN) is a result of infection by one or multiple types of four dengue viruses known as Dengue virus (DENV) 1-4. Identifying circulating serotype and genotype is epidemiologically important, however, it is challenging in resource limited areas. Moreover, transporting samples from the collation site to the laboratory in appropriate condition is an exigent task.

Expansion of the measles and rubella laboratory network, India.

Objective: To expand the measles and rubella laboratory network of India by integrating new laboratories.

Methods: In collaboration with the World Health Organization (WHO), the Indian government developed a 10-step scheme to systematically expand the number of laboratories performing serological and molecular testing for measles and rubella. The Indian Council of Medical Research and WHO identified suitable laboratories based on their geographical location, willingness, preparedness, past performance and adherence to national quality control and quality assurance mechanisms.

Molecular xenomonitoring of Dengue, Chikungunya and Zika infections: a year-round study from two Dengue endemic districts of central India.

Background & Objectives: Infections caused by arboviruses and transmitted by Aedes species mosquitoes are a serious health concern. India is endemic for diseases like Dengue, Chikungunya and recently Zika has been reported from few states. Vector control is the only way to contain these diseases, however, data regarding vectors from central India is lacking; to fulfill the lacuna we conducted this study.

Laboratory surveillance of chikungunya in Madhya Pradesh, India (2016-2017).

Background & Objectives: Chikungunya (CHIK) is a neglected, re-emerging arboviral disease. Limited information on CHIK-confirmed cases during interepidemic period is available from India. This surveillance study was conducted in Madhya Pradesh (MP), India, during the years 2016-2017, to provide information about CHIK cases.

Outbreaks of dengue in Central India in 2016: Clinical, laboratory & epidemiological study.

Background & Objectives: Dengue virus (DENV) causes outbreaks and sporadic cases in tropical and subtropical countries. Documenting intricacies of DEN outbreaks is important for future interventions. The objective of this study was to report clinical, laboratory and epidemiological features of DEN outbreaks reported in different districts of Central India in 2016.

Molecular studies on dengue viruses detected in patients from Central India.

Purpose: Dengue viruses (DENVs), the causative agents of dengue (DEN), are classified into four serotypes and several genotypes. Identifying circulating serotypes and genotypes has clinical and epidemiological importance; however, limited information in this regard is available from Central India. This laboratory-based study was done to fill this lacuna.

Molecular and epidemiological analysis of pandemic and post-pandemic influenza A(H1N1)pdm09 virus from central India.

Influenza A(H1N1)pdm09 virus pandemic struck India in 2009 and continues to cause outbreaks in its post-pandemic phase. Diminutive information is available about influenza A(H1N1)pdm09 from central India. This observational study presents epidemiological and molecular findings for the period of 6 years.

Seroprevalence of sexually transmitted viruses in the tribal population of Central India.

Objective: To determine the seroprevalence of human immunodeficiency virus (HIV), hepatitis B and C viruses (HBV, HCV), and herpes simplex virus type 2 (HSV-2) in the tribal population of central India.

Methods: A community-based cross-sectional survey was carried out in the tribal population of Jabalpur district. Blood samples were drawn from 326 patients with sexually transmitted infections (STIs) and 526 randomly selected adults.

Undernutrition & childhood morbidities among tribal preschool children.

Background & Objective: Undernutrition and various morbidities go hand in hand, particularly in children. Nutritional status is a sensitive indicator of community health and nutrition. The present study is an attempt to assess the nutritional status of pre-school children of Gond tribal community in Madhya Pradesh.
