A Systematic Review]]> https://www.researchpad.co/article/elastic_article_12507 Initial reports from China observed low rates of COVID-19 in children compared with adults. Emerging evidence suggests that children may be infected at the same rate as adults but are more likely to experience asymptomatic or mild disease.

<![CDATA[Unmasking the Actual COVID-19 Case Count]]> https://www.researchpad.co/article/elastic_article_12484 This report presents a novel approach to estimate the total number of COVID-19 cases in the United States, including undocumented infections, by combining the Centers for Disease Control and Prevention’s influenza-like illness surveillance data with aggregated prescription data. We estimated that the cumulative number of COVID-19 cases in the United States by 4 April 2020 was > 2.5 million.

<![CDATA[Clinical and Virological Characteristics of Acute Sinusitis in Children]]> https://www.researchpad.co/article/Nf41275cf-c8db-48e0-be42-21fb171e137f

Abstract

Background

Acute bacterial sinusitis is a frequent complication of viral upper respiratory infection (URI). We describe the clinical and virologic features of URIs that remain uncomplicated and those that precede an episode of sinusitis. We hypothesize that certain viruses are more likely to lead to acute sinusitis, and we compare viruses identified at the time of diagnosis of sinusitis with those identified early in the URI.

Methods

Children aged 48–96 months were followed longitudinally for 1 year. Nasal samples were obtained at surveillance visits, on Day 3–4 of the URI, and on Day 10, when sinusitis was diagnosed. Molecular diagnostic testing was performed on nasal washes for common respiratory viruses and pathogenic bacteria. A standardized score was used to quantify symptom severity.

Results

We evaluated 519 URIs, and 37 illnesses in 31 patients met the criteria for sinusitis. Respiratory syncytial virus was detected more frequently in URI visits that led to sinusitis, compared to in uncomplicated URIs (10.8% vs 3.4%; P = .05). New viruses were detected in 29% of sinusitis episodes, and their pattern was different than those patterns observed at surveillance. The median number of URIs per subject per year was 1 (range 0–9) in uncomplicated URI subjects and 3 (range 1–9) in sinusitis subjects (P < .001).

Conclusions

Children who developed sinusitis experienced more frequent URIs, compared to children whose URIs remained uncomplicated. When nasal samples were obtained on the day of diagnosis of acute sinusitis, nearly 30% of children had a new virus identified, suggesting that some children deemed to have sinusitis were experiencing sequential viral infections.
