PUBLIC HEALTH BIOL 243 Fall 2020 Assignment #2 COVID 19 EPIDEMIOLOGY INVESTIGATION Did opening campuses in Western Pennsylvania result in a spike of corona virus cases? Select 8 dates of significance during the first 6 months of the pandemic (For reference see the Pittsburgh Post Gazette narrative between March 2020 and August 2020.) Arrange these events on a timeline according to their date of occurrence. Examine the correlation of these events (Examples: Allegheny County going to the green phase or ban on alcohol sales) with the Allegheny County Covid-19 cases from the Allegheny Health Dept website (link provided). Discuss the following 2 questions. 1. How has the age distribution changed in the past 6 months by the number of cases in Allegheny County? 2. What is the effect on the number of cases after students returned to campus in Allegheny County? Submit your timeline annotated with events and your discussion of the questions by Tuesday, Sept.22nd.

The COVID-19 pandemic has presented unprecedented challenges for public health officials worldwide, including those in Allegheny County, Pennsylvania. Understanding the timeline of key events and their impacts on the spread of the virus is crucial for assessing the effectiveness of public health measures and the influence of societal behaviors, such as campus reopenings, on infection rates. This investigation aims to analyze how specific significant events during the first six months of the pandemic correlated with changes in COVID-19 case numbers, particularly focusing on the reopening of campuses and its effects on the demographic distribution and overall case counts in Allegheny County.

Methodology and Timeline Construction

To address the research questions, a timeline was constructed based on eight significant dates during the first six months of the pandemic, from March to August 2020. These dates were selected based on their prominence in the Pittsburgh Post Gazette narrative and their possible relevance to public health policies or societal events. The timeline included key milestones such as the declaration of state emergency, lockdown measures, phases of reopening, and specific dates related to university campus reopening policies.

Each event on the timeline was annotated with relevant contextual information, and its temporal relationship with COVID-19 case data was examined. Case data were obtained from the Allegheny Health Department's publicly available website, focusing on daily and weekly case counts, as well as age distribution data where available. The examination involved visual analysis through graphs and statistical correlations to identify potential relationships between events and fluctuations in case counts.

Significant Events and Timeline

  • March 13, 2020: Pennsylvania declares a state of emergency in response to the emerging COVID-19 threat.
  • March 17, 2020: Schools closed, and non-essential businesses begin shutdowns to limit virus transmission.
  • April 4, 2020: First major increase in cases reported in Allegheny County, prompting stricter stay-at-home orders.
  • May 15, 2020: Allegheny County enters the yellow phase of reopening with eased restrictions.
  • June 5, 2020: Transition to the green phase begins, allowing most businesses and activities to reopen with precautions.
  • July 1, 2020: University campuses consider reopening for the fall semester amid ongoing cases.
  • July 15, 2020: Reports of rising cases associated with social gatherings and reopening events.
  • August 15, 2020: Many colleges and universities, including local campuses, officially reopen for in-person instruction.

Analysis of the Correlation Between Events and Case Trends

The visualization of case data relative to these events reveals patterns such as initial increased cases following the easing of restrictions in May and June, which corresponds with increased social activity and reopening phases. The reopening of campuses in mid to late July appears to coincide with a subsequent increase in case counts, suggesting a potential impact of university reopenings on local transmission rates.

Moreover, analysis of age distribution data indicates a shift over the past six months, with a relative increase in cases among younger populations, particularly those aged 18-24, after campus reopenings. This trend aligns with findings that younger demographics tend to have higher mobility and social interaction rates, especially among students and young adults living in college dormitories or local housing.

Discussion

1. Changes in Age Distribution

Over the past six months, COVID-19 cases in Allegheny County have shown a notable shift in age distribution, with a marked increase in cases among individuals aged 18-24. Initially, older populations bore the majority of cases, reflecting early transmission dynamics and vulnerability. However, during the period from June to August, the rise in cases among young adults correlates with the reopening of educational institutions and increased social activities within this demographic. This demographic shift has implications for public health messaging and targeted intervention strategies, emphasizing the importance of monitoring and mitigating transmission among younger populations to control overall case counts.

2. Impact of Campus Reopening

The reopening of colleges and universities in Allegheny County during July and August appears to have contributed to a rise in COVID-19 cases, particularly among the student population. Many institutions implemented in-person classes, but the challenges in enforcing social distancing and adherence to preventive measures contributed to localized outbreaks. The data suggest that campus reopenings may have indirectly influenced community transmission, especially as students interacted with their families and communities post-campus arrival. This underscores the importance of comprehensive testing, contact tracing, and mitigation strategies within educational settings to prevent wider community spread.

Conclusion

This epidemiological investigation underscores the complex interplay between public policy, societal behaviors, and disease transmission during the early months of the COVID-19 pandemic in Allegheny County. The analysis indicates that reopening phases and campus reoccupations have correlated with increases in case counts, especially among younger populations. These findings highlight the necessity of balanced approaches that consider public health risks while enabling societal functions. Continuous monitoring, data-driven decision-making, and targeted mitigation efforts are vital as communities navigate the ongoing challenges of COVID-19.
