Epidemiology is the study of how diseases spread through populations and what factors influence their patterns. Rather than focusing on individual patients, this field examines broader trends to identify outbreaks, track transmission, and guide public health decisions. By analyzing data on infection rates and risk factors, researchers work to prevent future health crises and protect communities worldwide.

On Gist.Science, we process every new preprint in this category directly from medRxiv to make these critical findings instantly accessible. For each study, we provide both a plain-language explanation for general readers and a detailed technical summary for specialists. This dual approach ensures that vital insights into disease dynamics are understood clearly and quickly by everyone who needs them.

Explore the latest research below to see how scientists are currently mapping disease trends and developing strategies to safeguard global health.

Estimating probabilities of malaria importation in southern Mozambique through P. falciparum genomics and mobility patterns

By integrating human mobility data with *P. falciparum* genomics, this study developed a novel Bayesian approach to quantify malaria importation in southern Mozambique, revealing that nearly half of infections in targeted elimination districts are imported—primarily from Inhambane province—and highlighting the need for fine-scale, source-targeted strategies to achieve malaria elimination.

Modeling the impact of adherence to U.S. isolation and masking guidance on SARS-CoV-2 transmission in office workplaces in 2021-2022

A network-based mathematical model of the 2021–2022 US epidemic reveals that while moderate adherence to isolation and masking guidance in office workplaces helps reduce transmission, increasing adherence yields limited additional benefits due to low contact intensity and hybrid work, highlighting that community-wide adoption of these non-pharmaceutical interventions is more effective for reducing infections and deaths.

The evolving epidemiology of scrub typhus in Thailand (2003-2024): insights from latent process modelling of national surveillance data

By integrating 22 years of national surveillance data with seroprevalence and antibody kinetics through latent process modelling, this study reveals that scrub typhus transmission in Thailand extends significantly beyond its traditional northern focus into the northeast and south, while the at-risk demographic has progressively shifted toward older adults who face the highest mortality, necessitating regionally tailored surveillance and age-targeted clinical strategies.

Coupling models of within-human, human-to-mosquito, and within-mosquito malaria parasite dynamics to identify key drivers of malaria transmission

By integrating data from a human challenge study into a multi-scale mathematical model, this study quantifies key biological parameters of human-to-mosquito malaria transmission and identifies that parasite multiplication and gametocyte maturation drive the onset of infectiousness, while circulating gametocyte availability and fertilization efficiency determine the infectiousness of established infections.

Assessing the impact of social prescribing on health service utilisation: Evidence from the UK

Drawing on longitudinal data from 4,547 participants in the UK, this study utilizes Bayesian growth curve modelling to demonstrate that social prescribing significantly reduces health service utilization across primary and secondary care settings, with substantial decreases observed in GP visits, A&E attendances, and hospital admissions.

Unscheduled bleeding and endometrial cancer in women on postmenopausal hormone replacement therapy and their matched controls: protocol for a descriptive cohort study using the Orchid-e database

This paper outlines the protocol for a descriptive cohort study using the ORCHID-e database to investigate the diagnostic accuracy of unscheduled bleeding for endometrial cancer in postmenopausal women taking hormone replacement therapy compared to matched controls, aiming to inform guidelines on unnecessary referrals and invasive testing.
