Article Abstract
Background: The number of deaths and people infected with coronavirus disease 2019 (COVID-19) in Brazil has steadily increased in the first few months of the pandemic. Despite the underreporting of coronavirus cases by government agencies across the country, São Paulo has the highest rate among all Brazilian states.
Methods: To identify the highest-risk municipalities during the initial outbreak, we utilized daily confirmed case data from official reports between February 25 and May 5, 2020, which were aggregated to the municipality level. A prospective space-time scan statistic was conducted to detect active clusters in three different time periods.
Results: Our findings suggest that approximately 4.6 times more municipalities belong to a significant space-time cluster with a relative risk (RR) > 1 on May 5, 2020.
Conclusions: Our study demonstrated the applicability of the space-time scan statistic for the detection of emerging clusters of COVID-19. In particular, we identified the clusters and RR of municipalities in the initial months of the pandemic, explaining the spatiotemporal patterns of COVID-19 transmission in the state of São Paulo. These results can be used to improve disease monitoring and facilitate targeted interventions.

Background: Liver cancer remains an important issue of public health management in the United States, and the geographical differences in mortality indicators are noticeable. Understanding space-time models and basic risk factors is important for targeted public health mediation.
Methods: This study examined liver cancer mortality at the county level across the United States from 2010 to 2019.

Objective: To estimate years of life lost (YLL) due to cervical cancer (CC) at the subnational level in Argentina from 2001 to 2020 and identify spatial and spatiotemporal clusters of CC mortality.
Methods: Ecological time-series study. Mortality data were obtained from the Directorate of Health Statistics and Information, and population data, from the censuses conducted by the National Statistics and Census Institute and intercensal projections.
Spatial and temporal epidemiology of FMD in Bhutan (2011-2019).

Background: Foot and Mouth Disease (FMD) is an important disease in livestock in Bhutan due to its significant social and economic impacts to the farmers as well as to the government. FMD outbreaks continue to occur every year with greater frequency in some parts of the country despite the implementation of control measures. It is imperative to understand the current patterns of the disease for planning effective control programs.

Introduction: Despite emerging disease syndromes in Australian Thoroughbred horses in recent years, there is no formal surveillance for fetal loss in the industry. This study aimed to characterise the distribution of equine pregnancy loss > 45 days of gestation in a major Thoroughbred breeding region to provide insights into causes, prevention, and surveillance feasibility.
Methods: Data were collected from 574 fetal loss submissions to veterinary pathology services between February 2015 and November 2021.

Background: Breast cancer is the most common malignant tumor affecting women, with significant space-time disparities in incidence and mortality, underscoring the importance of exploring its dynamic trends and clustering patterns.
Methods: The data were obtained from the Global Burden of Disease Study 2021. The study employed multiple spatial analytical methods to systematically examine the space-time distribution patterns of female breast cancer incidence and mortality worldwide.
