Following the Food and Drug Administration's release of recommendations on limiting the use of products containing hexachlorophene (HCP) for bathing newborn infants, 142 hospitals spontaneously reported outbreaks of neonatal staphybococcal disease. Epidemiologic investigations were carried out in 73 of these hospitals; 66 had confirmed outbreaks of neonatal staphylococcal disease. In 60 of the 66, discontinuation of HCP bathing of newborn infants preceded the epidemic. Alterations in handwashing policies did not appear implicated in any outbreak investigated. These findings suggested that discontinuation of HCP bathing of newborn infants was associated with increased incidence of neonatal staphylococcal disease.

AbstractBackgroundShiga toxin–producing Escherchia coli (STEC) O157:H7 is a zoonotic pathogen that causes numerous food and waterborne disease outbreaks. It is globally distributed, but its origin and the temporal sequence of its geographical spread are unknown.MethodsWe analyzed whole-genome sequencing data of 757 isolates from 4 continents, and performed a pan-genome analysis to identify the core genome and, from this, extracted single-nucleotide polymorphisms. A timed phylogeographic analysis was performed on a subset of the isolates to investigate its worldwide spread.ResultsThe common ancestor of this set of isolates occurred around 1890 (1845–1925) and originated from the Netherlands. Phylogeographic analysis identified 34 major transmission events. The earliest were predominantly intercontinental, moving from Europe to Australia around 1937 (1909–1958), to the United States in 1941 (1921–1962), to Canada in 1960 (1943–1979), and from Australia to New Zealand in 1966 (1943–1982). This pre-dates the first reported human case of E. coli O157:H7, which was in 1975 from the United States.ConclusionsInter- and intra-continental transmission events have resulted in the current international distribution of E. coli O157:H7, and it is likely that these events were facilitated by animal movements (eg, Holstein Friesian cattle). These findings will inform policy on action that is crucial to reduce the further spread of E. coli O157:H7 and other (emerging) STEC strains globally.

Abstract Background: Travel patterns of humans play a major part in the spread of infectious diseases. This was evident in the geographical spread of COVID-19 in the United States. However, the impact of this mobility and the transmission of the virus due to local travel, compared to the population traveling across state boundaries, is unknown. This study evaluates the impact of local vs. visitor mobility in understanding the growth in the number of cases for infectious disease outbreaks. Methods: We use two different mobility metrics, namely the local risk and visitor risk extracted from trip data generated from anonymized mobile phone data across all 50 states in the United States. We analyzed the impact of just using local trips on infection spread and infection risk potential generated from visitors' trips from various other states. We used the Diebold-Mariano test to compare across three machine learning models. Finally, we compared the performance of models, including visitor mobility for all the three waves in the United States and across all 50 states. Results: We observe that visitor mobility impacts case growth and that including visitor mobility in forecasting the number of COVID-19 cases improves prediction accuracy by 34. We found the statistical significance with respect to the performance improvement resulting from including visitor mobility using the Diebold-Mariano test. We also observe that the significance was much higher during the first peak March to June 2020. Conclusion: With presence of cases everywhere (i.e. local and visitor), visitor mobility (even within the country) is shown to have significant impact on growth in number of cases. While it is not possible to account for other factors such as the impact of interventions, and differences in local mobility and visitor mobility, we find that these observations can be used to plan for both reopening and limiting visitors from regions where there are high number of cases.

Measles Outbreaks

As measles cases continue to rise in the United States and elsewhere, public health officials, health care providers and elected officials alike are facing critical questions of how to protect the health of the public from current and future vaccine preventable disease outbreaks while still preserving the religious and personal autonomy of the populations they serve. As measles cases are being examined and carefully managed, public health officials are also tasked with revisiting vaccination policies and agendas to determine the best evidence-based interventions to control this epidemic. To determine the best course of action for the public's interest, research and current literature must be examined to protect and promote the health and wellbeing of those currently affected by the measles outbreak and those yet to be exposed.

ABSTRACT This paper describes the whole-genome sequences for three Streptococcus agalactiae serotype Ia isolates. The isolates were recovered from the brains of clinically sick tilapia, Oreochromis niloticus, that were suffering from streptococcosis. One isolate was from tilapia in the United States and the other two from fish in China.

Despite an increasing number of techniques that are designed to mitigate microbial contamination of food and the resulting food borne disease outbreaks, the United States and many other countries across the world continue to experience impressive numbers of such outbreaks. Microbial contamination can occur during activities that take place in the pre-harvest environment or in the processing facility post-harvest. Current treatments of food that are aimed at reducing bacterial numbers may be only partially effective because of the development of bacterial resistance, the formation of bacterial biofilms, and inactivation of the treatment compound by the food products themselves. This Special Issue will include basic research approaches that are aimed at enhancing our understanding of how contamination occurs throughout the food processing chain, as well as more immediate and applied approaches to the development and use of novel anti-microbials to combat microbes in food. Novel techniques that aim to evaluate the efficacy of novel anti-microbials are included. Overall, we present a broad spectrum of novel approaches to reduce microbial contamination on food at all stages of production.
