    Abstract After SARS-CoV-2 set foot in India, the Indian Government took a number of steps to limit the spread of the disease in the country. This study involves assessing how the disease affected the population in the initial days of the epidemic. Data was collected from government controlled and crowdsourced websites and then put through analysis and calculations. With a study on age and sex parameters of 413 patients, the median age of the affected individuals was found out to be 36 years (IQR 25-54 years) with 20-39 years males being the most affected group. The number of affected males (66.34%) was more than that of the females(33.66%).Using SIR model, the range of contact rate(β) of India was calculated and the role of public health interventions was assessed which proved that the interventions were effective for a little while but the effect reduced due to violations.

    Abstract Background: After SARS-CoV-2 set foot in India, the Government took a number of steps to limit the spread of the virus in the country. This included restricted testing, isolation, contact tracing and quarantine, and enforcement of a nation-wide lockdown starting 25 March 2020. The objectives of this study were to i) describe the age,gender distribution and mortality among COVID-19 patients identified till 14 April 2020 and predict the range of contact rate; and ii) predict the number of active COVID-19 patients after 40 days of lockdown. Methods: We used a cross-sectional descriptive design for first objective and a susceptible-infected-removed model for in silico predictions. We collected data from government-controlled and crowdsourced websites. Results: Studying age and gender parameters of 1161 Indian COVID-19 patients, the median age was 38 years (IQR, 27-52) with 20-39 year-old males being the most affected group. The number of affected patients were 854 (73.6%) men and 307 (26.4%) women. If the current contact rate continues (0.25-27), India may have 110460 to 220575 infected persons at the end of 40 days lockdown. Conclusion: The disease is majorly affecting a younger age group in India. Interventions have been helpful in preventing the worst-case scenario in India, but will be unable to prevent the spike in number of cases.

    Abstract Present investigation deals with the diversity of cyanobacteria in fresh water lakes and water bodies of Himachal Pradesh. During the study, 10 genera and 18 species belonging to the families Chroococcaceae, Oscillatoriaceae, Nostocaceae and Rivulariaceae have been collected and identified. Among these, 12 species were non- heterocystous and 6 species were heterocystous (N₂ fixing) showing morphological diversities from unicellular to multicellular and colonial to filamentous forms. Physico-chemical analysis of water for temperature, pH, alkalinity, free CO₂, total hardness, chlorides etc. was done. The most abundant distributed cyanobacteria were Oscillatoria sancta, Lyngbya major among non-heterocystous forms followed by Chroococcus minutus, Aphanothece castagnei, Microcystis aeruginosa whereas Nostoc punctiforme, Calothrix braunii and Anabaena iyengarii were among the heterocystous forms. These species were found during August to October. Calothrix braunii, Nostoc punctiforme, Cylinderospermum stagnale and Calothrix brevissima have been recorded for the first time. Present study of Cyanobacterial diversity and their distributional pattern has significance for agriculture as renewable biofertilizers and for their potential as repository of bioactive compounds.
