Long COVID poses major public-health challenges, making effective surveillance essential. This study evaluates whether Google Trends can improve monitoring of long COVID symptoms. Using 33 search terms and 20 related topics identified from CDC and scite sources, researchers created a merged search volume (MSV) metric to address data limitations. They found four symptom topics that rise in search popularity before “long COVID,” and nine that rise afterward. MSV successfully forecasted long COVID prevalence, indicating that Google Trends–based analytics can support risk management and early detection.

This study introduces a global network analysis to assess COVID-19 pandemic risk by linking 164 countries based on the co-movement of newly confirmed cases. When many countries experience rising cases simultaneously, the network’s density, clustering, and assortativity indicate heightened global spread, providing early warning signals as early as late February 2020. The authors develop two indicators: a preparedness risk score for predicting spread and a severity risk score for monitoring control. Asia contributed 25–50% of preparedness risk after February 2020, while the Americas contributed about 40% in July. By December 2020, America and Europe contributed about 90% of severity risk. An online dashboard tracks these metrics.

Family caregivers often face heavy stress that can lead to psychosocial health problems, but early detection can help prevent long-term harm. This study developed an Automatic Speech Analytics Program (ASAP) to identify caregiver stress levels using speech data. Testing with 100 Cantonese-speaking caregivers showed that ASAP could distinguish high versus low stress burden with 72% accuracy. The results demonstrate the potential of digital tools to support psychosocial assessments. Unlike traditional evaluations that require specialists and multiple interviews, ASAP offers a rapid, cost-effective first-line screening method, enabling timely referral to social workers or healthcare professionals for further assessment and treatment.

This paper presents a modified method for estimating high-dimensional dynamic variance–covariance matrices using risk factor mapping to efficiently model dependence among asset returns in large portfolios. The key idea is to capture time-varying dependence through the co-movement of returns with underlying risk factors, allowing the mapping matrices themselves to change over time. Risk factors are flexibly modeled using a copula MGARCH framework. Because the number of parameters depends on the number of risk factors rather than the number of assets, the approach is highly scalable. Bayesian methods are used for parameter and risk-measure estimation. An empirical study on the Hong Kong stock market demonstrates the method’s practical effectiveness.
