In this paper, we investigate the fractional epidemic mathematical model and dynamics of COVID-19. The Wuhan city of China is considered as the origin of the corona virus. The novel corona virus is continuously spread its range of effectiveness in nearly all corners of the world. Here we analyze that under what parameters and conditions it is possible to slow the speed of spreading of corona virus. We formulate a transmission dynamical model where it is assumed that some portion of the people generates the infections, which is affected by the quarantine and latent time. We study the effect of various parameters of corona virus through the fractional mathematical model. The Laguerre collocation technique is used to deal with the concerned mathematical model numerically. In order to deal with the dynamics of the novel corona virus we collect the experimental data from 15th-21st April, 2020 of Maharashtra state, India. We analyze the effect of various parameters on the numerical solutions by graphical comparison for fractional order as well as integer order. The pictorial presentation of the variation of different parameters used in model are depicted for upper and lower solution both.

Assessing the impact of the COVID-19 pandemic on neglected tropical diseases in India: a perspective.
Front Public Health

Indian Institute of Public Health Delhi, New Delhi, India.
The COVID-19 pandemic has significantly challenged healthcare systems worldwide, particularly in India, a country already burdened with a high prevalence of Neglected Tropical Diseases (NTDs). This perspective examines the pandemic's direct and indirect impacts on the prevalence, diagnosis, and management of NTDs in India. Using a narrative review approach, we analyzed literature published between January 2020 and September 2023 from databases such as PubMed, Scopus, and Google Scholar, along with grey literature.

Article Synopsis
- The COVID-19 pandemic has heightened psychological distress, with factors like childhood trauma and maladaptive personality traits contributing to mental health issues.
- A study of 6,451 adults identified key connections between childhood trauma, maladaptive traits, and increased psychopathological symptoms, using self-reported measures and structural equation modeling.
- Findings suggest that targeting emotion dysregulation and mentalizing may be beneficial in developing interventions to alleviate pandemic-related psychological distress, especially for those with childhood trauma and maladaptive traits.
Clinical characteristics and prognostic factors of COVID-19 in rheumatic patients and their family members: a retrospective study.

Article Synopsis
- Patients with rheumatic diseases tend to recover from COVID-19 faster (average 13 days) compared to their family members (average 16 days), despite being on immunosuppressive treatments.
- The study found that rheumatic patients have a lower risk of developing moderate to severe COVID-19, with pre-infection use of NSAIDs linked to a higher chance of mild cases.
- Patients using disease-modifying anti-rheumatic drugs (DMARDs) before infection were significantly less likely to develop severe cases compared to those who were not on these medications.
COVID-19 and social distancing: pandemic has altered social relationships and contacts in older adults over 4 years.

Introduction: Social isolation is a main risk factor for loneliness, health issues and psychological diseases. With its restriction measures, the coronavirus pandemic has led to an objective reduction in meaningful interactions, communication, and social contacts in general (social isolation). However, it has been shown that older adults cope differently with social isolation.

Background: There is limited data that assessed the changes in public confidence in routine childhood and adult vaccines after Corona Virus Disease-2019 (COVID-19) pandemic. We, therefore, assessed these changes and the reasons; if any; for these changes and measured the impact of COVID-19 on peoples' thoughts regarding routine vaccinations in Saudi Arabia.
Methods: We undertook a cross-sectional online study in Saudi Arabia from November 2023 to April 2024.
