We report acute Oropouche virus infections in 2 previously healthy women from a nonendemic region of Brazil outside the Amazon Basin. Infections rapidly progressed to hemorrhagic manifestations and fatal outcomes in 4-5 days. These cases highlight the critical need for enhanced surveillance to clarify epidemiology of this neglected disease.

- The Covid-19 pandemic has caused widespread suffering and economic disruption globally, making it crucial for authorities to understand the disease's spread and characteristics for effective interventions.
- A hybrid model incorporating local SIR models and population flow networks provides a more accurate representation of contagion dynamics compared to traditional models that assume uniform contact rates among municipalities.
- By highlighting the importance of local variations and inter-municipality transport, the study suggests that early restrictions on movement can significantly help in controlling the spread of the virus.
Dengue infection is a public health problem with a complex distribution. The physical means of propagation and the dynamics of diffusion of the disease between municipalities need to be analysed to direct efficient public policies to prevent dengue infection. The present study presents correlations of occurrences of reported cases of dengue infection among municipalities, self-organized criticality (SOC), and transportation between areas, identifying the municipalities that play an important role in the diffusion of dengue across the state of Bahia, Brazil.
