Throughout the COVID-19 pandemic, headlines ranging from “Coronavirus forecasts are grim: It’s going to get worse” to “Covid-19 cases and deaths in the US will fall over the next four weeks, forecast predicts” have dominated the news (Achenbach, 2020; Kallingal, 2021). The weekly-published Center for Disease Control and Prevention (CDC) COVID-19 forecasts have become the go-to forecasts for the media, the public, and various levels of government (Cramer et al., 2021). These projections, generated from epidemiological forecasting, not only inform the public’s caution towards the pandemic but are also crucial for officials to create public health guidelines and allocate resources in hospitals (Gibson et al., 2020). But where do these predictions come from?

Credible, reliable and consistent information to the public, as well as health professionals and decision makers, is crucial to help navigate uncertainty and risk in times of crisis and concern. Traditionally, information and health communications issued by respected and established government agencies have been regarded as factual, unbiased and credible. The U.S. Centers for Disease Control and Prevention (CDC) is such an agency that addresses all aspects of health and public health on behalf of the U.S Government for the benefit of its citizens. In July 2020, the CDC issued guidelines on reopening schools which resulted in open criticism by the U.S. President and others, prompting a review and publication of revised guidelines together with a special “Statement on the Importance of Reopening Schools under COVID-19.” We hypothesize that this statement introduced bias with the intention to shift the public perception and media narrative in favor of reopening of schools. Using a mixed methods approach, including an online text analysis tool, we demonstrate that document title and structure, word frequencies, word choice, and website presentation did not provide a balanced account of the complexity and uncertainty surrounding school reopening during the COVID-19 pandemic. Despite available scientific guidance and practical evidence-based advice on how to manage infection risks when reopening schools, the CDC Statement was intentionally overriding possible parent and public health concerns. The CDC Statement provides an example of how political influence is exercised over the presentation of science in the context of a major pandemic. It was withdrawn by the CDC in November 2020.

Background The Centers for Disease Control and Prevention (CDC) is a national public health protection agency in the United States. With the escalating impact of the COVID-19 pandemic on society in the United States and around the world, the CDC has become one of the focal points of public discussion. Objective This study aims to identify the topics and their overarching themes emerging from the public COVID-19-related discussion about the CDC on Twitter and to further provide insight into public's concerns, focus of attention, perception of the CDC's current performance, and expectations from the CDC. Methods Tweets were downloaded from a large-scale COVID-19 Twitter chatter data set from March 11, 2020, when the World Health Organization declared COVID-19 a pandemic, to August 14, 2020. We used R (The R Foundation) to clean the tweets and retain tweets that contained any of five specific keywords—cdc, CDC, centers for disease control and prevention, CDCgov, and cdcgov—while eliminating all 91 tweets posted by the CDC itself. The final data set included in the analysis consisted of 290,764 unique tweets from 152,314 different users. We used R to perform the latent Dirichlet allocation algorithm for topic modeling. Results The Twitter data generated 16 topics that the public linked to the CDC when they talked about COVID-19. Among the topics, the most discussed was COVID-19 death counts, accounting for 12.16% (n=35,347) of the total 290,764 tweets in the analysis, followed by general opinions about the credibility of the CDC and other authorities and the CDC's COVID-19 guidelines, with over 20,000 tweets for each. The 16 topics fell into four overarching themes: knowing the virus and the situation, policy and government actions, response guidelines, and general opinion about credibility. Conclusions Social media platforms, such as Twitter, provide valuable databases for public opinion. In a protracted pandemic, such as COVID-19, quickly and efficiently identifying the topics within the public discussion on Twitter would help public health agencies improve the next-round communication with the public.

BACKGROUND The emergence of SARS-CoV-2, the virus that causes COVID-19, has led to a widespread global pandemic not seen since the 1918 influenza outbreak. The empirical question is if the current pandemic would attenuate from an approach taken by President Wilson used during the Influenza Pandemic of 1918 that killed some 675,000 Americans and up to 50 million people worldwide or by the approach President Franklin Roosevelt implemented to control malaria in the 1940s. OBJECTIVE To test COVID-19 control policies at the federal and state level with surveillance metrics including 1) speed, 2) acceleration, 3) jerk, 4) 7-day persistence. We will surveil COVID transmission using standard surveillance techniques, novel rates of increase and persistence, combined with overall caseload. Novel indicators improve our understanding of where and how rapidly SARS-CoV-2 is transmitting, and quantifies shifts in the rate of acceleration or deceleration by state to inform policy targeting mitigation and prevention strategies in the U.S. METHODS Using a longitudinal trend analysis study design, we extracted 60 days of COVID data from public health registries. We use an empirical difference equation to measure daily case numbers in 50 US states and Washington D.C. as a function of the prior number of cases, the level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments (GMM) approach by implementing the Arellano-Bond estimator in R. RESULTS There is variation between and within states with some exemplars of good public health practice such as VT, NH, and ME. The overall U.S. caseload and increases in rates of infection translate into the country with highest caseload of coronavirus infections and deaths. The US 7-Day Persistence rate means super spreader events such as rallies, college parties, and other social gatherings not only infect large numbers of people but those infections echo forward with additional infections. Moving forward, blaming the virus on China or Spain was neither warranted nor helpful in controlling COVID-19 or the Influenza Pandemic; nor is censorship of the media or misinformation via social media. Other obstacles to recovery such as expressing skepticism of science and overt denial of the facts didn’t work for President Wilson during the 1918 influenza pandemic nor is it helpful today. We need a Roosevelt and not a Wilson response to the pandemic to return to normal. The current U.S. response to COVID-19 parallels President Wilson’s response to the 1918 Influenza Pandemic that killed 50 million people based on 1) no national response to control the outbreak; 2) misinformation; 3) unclear communication with the public; 4) widespread mistrust and panic.

Abstract Background The public health workforce (PHW) is a key component of a country’s public health system. Since the outbreak of SARS (severe acute respiratory syndrome) in 2003, the scale of PHW in China has been continuously expanding, but policymakers and researchers still focus on the distribution of public health personnel, especially the regional inequality in such distribution. We aimed to identify the root cause of PHW inequality by decomposing different geographical units in China. Methods This study was based on data from a nationwide survey, which included 2712 county-level data. The distribution of the PHW in geographical units was evaluated by the Gini coefficient and Theil T index, and inequalities at regional, provincial, and municipal levels were decomposed to identify the root causes of inequalities in the PHW. Additionally, the contextual factors affecting the distribution of the PHW were determined through regression analysis. Results The overall inequality results show that health professional and field epidemiological investigators faced worse inequality than the staff. In particular, field epidemiological investigators had a Gini coefficient close to 0.4. Step decomposition showed that within-region inequalities accounted for 98.5% or more of overall inter-county inequality in the distribution of all PHW categories; provincial decomposition showed that at least 74% of inequality is still distributed within provinces; the overall contribution of within-municipal inequality and between-municipal inequality was basically the same. Further, the contextual factor that influenced between-municipality and within-municipality inequality for all three categories of PHWs was the agency building area per employee. Per capita GDP had a similar effect, except for between-municipality inequality of professionals and within-municipality inequality of field epidemiological investigators. Conclusions The successive decomposition showed that inequality is mainly concentrated in counties at the within-province and within-municipal levels. This study clearly suggests that the government, especially the municipal government at the provincial level, should increase financial investment in Centers for Disease Control and Prevention (CDCs) with worse resource allocation in their jurisdiction through various ways of compensation and incentives, enhance their infrastructure, and improve the salary of personnel in these institutions, to attract more public health professionals to these institutions.

ABSTRACT As nonacademic careers in science have become less and less “alternative,” one field that has consistently attracted early-career virologists is public health research. The desire to make tangible contributions to public health needs and better protect the public from infectious disease often motivates the transition. In this career-related Gem, two academically trained virologists offer insights into pursuing a research career in public health at the Centers for Disease Control and Prevention.
