Today’s summary is based on a review of 604 articles (520 published, 84 in preprint)<\/em><\/p>\n \t\t\t\t<\/p>\n Two SARS-CoV-2 outbreaks in April, 2020 were identified among office workers in Washington, DC. The study identified two factors potentially associated with SARS-CoV-2 infection and transmission in the workplace: a significantly higher percentage of seropositive participants lived with someone who had a confirmed positive test result (13%) than those who were seronegative (1%), and more (60% vs. 32%) seropositive participants traveled by taxi after the cancellation of nonessential gatherings on March 11, 2020. There was no significant difference in workplace mitigation activities between seropositive and seronegative participants, including using a face covering most of the time or always, maintaining a distance of\u00a0>6 feet, and washing hands or using hand sanitizer\u00a0>5 times per day.\u00a0<\/span><\/p>\n Sami et al.

The authors identified the phenomenon after observing a green pigment in protein precipitate of recombinant SARS-CoV-2 spike produced in human cell lines. Binding to biliverdin inhibited the ability of immune sera and a subset of monoclonal antibodies to neutralize the virus. The study findings suggest that the spike N-terminal domain (NTD), a key site for antibody binding, is a dynamic and flexible region, and that interaction with biliverdin can cause conformational changes in the NTD such that it may evade the immune response. Spike protein isolated from endemic coronaviruses (NL63 and OC43) did not have similar properties.\u00a0<\/span><\/p>\n Rosa et al. (Jan 26, 2021).

Greater first wave severity was also associated with slower second wave growth rate. Possible explanations for these trends put forth by the authors were changes in the demographics of the subpopulations sampled by testing, increased social distancing behaviors, or changes in population immunity.\u00a0<\/span><\/p>\n Brookes et al.

Of 1,160,062 patients aged 80 or over and not living in a care home, 41% had been vaccinated. Within this group, there were substantial differences in vaccination by ethnicity (white 43% vaccinated, Black 21%) and across rankings of deprivation (least deprived 45%, most deprived 38%). In the 70-79 age cohort, 4% had been vaccinated. Among those age 65-70 who were care home residents the vaccine coverage was 33%.

In addition, around 3% of recovered patients demonstrated effective cross-neutralizing IgG antibodies to SARS-CoV-1 without known prior exposure to the virus. Key factors in predicting the development of SARS-CoV-2 neutralizing activity in mild cases were seroreactivity, age, time since disease onset, and fever.\u00a0<\/span><\/p>\n Vanshylla et al.

This variant was also modestly more resistant to neutralization with convalescent plasma (about 3 fold) and sera from people who had received the Pfizer or Moderna vaccines (about 2 fold). The B.1.351 (South Africa) variant resisted neutralization by most NTD mAbs, multiple individual mAbs directed against the RBD, convalescent plasma (about 11-33 fold), and sera from vaccinated people (about 6.5-8.6 fold). The authors note that loss of neutralizing activity against the B.1.1.7 variant is unlikely to have an adverse impact, while the reduction in activity levels against the B.1.351 variant were potentially concerning.\u00a0<\/span><\/p>\n Wang et al.

Obese participants had a lower elevation in body temperature (38.1C vs. 38.7C) but no other clinical differences between the groups were observed, including differences in time on ventilator, ICU length of stay, or 40-day mortality.

Despite the in vitro<\/i> susceptibility of cytotrophoblasts (a type of placental cell) to SARS-CoV-2 infection, viral RNA was detected in the placentas of only around 13% of women in the cohort, including those with severe disease and high viral loads. Bulk transcriptomic analysis of the placenta demonstrated clear differences in the expression of genes associated with immune responses, which the authors suggested could represent immune activation at the placenta even in the absence of detectable virus. However, only minor histological differences (an increase intervillous fibrin in the placentas from COVID-infected women) were observed when comparing the placentas from COVID-infected women to controls. \u00a0<\/span><\/p>\n Lu-Culligan et al.

Polio cases increased by about fourfold in polio endemic countries. Factors contributing to low vaccine coverage included fear of being exposed to the virus at health care facilities, restriction on city-wide movements, shortage of workers, and diversion of resources from child health to address the pandemic. 10 of these studies focused on campaigns in high-income countries.<\/p>\n Lassi et al.
