AI Article Synopsis

  • COVID-19 containment measures significantly reduced the prevalence of invasive pneumococcal disease, impacting carriage rates among adults aged 64 and older.
  • During the study from January 2019 to December 2021, nasal and throat swabs revealed a decrease in pneumococcal carriage from 12.9% before lockdown to 4.2% during lockdown.
  • As society reopened, the carriage rate rebounded to 12.1%, indicating that pandemic measures influenced pneumococcal transmission.

Article Abstract

Background: COVID-19 containment measures reduced the burden of invasive pneumococcal disease. Data on pneumococcal carriage rates among adults during the pandemic are scarce.

Methods: Naso- and oropharyngeal swabs and questionnaires were collected during January 2019 to December 2021 from adults ≥64 years of age. Carriage was determined by PCR.

Results: A total of 1556 participants provided paired naso- and oropharyngeal swabs. Their median age was 74 years (IQR, 70-79). DNA was detected in 146 (9.4%) oropharyngeal swabs and 34 (2.2%) nasopharyngeal. The carriage rate decreased from 12.9% (95% CI, 10.1%-16.1%, n = 66/511) prelockdown (January 2019-February 2020) to 4.2% (95% CI, 2.0%-7.5%, n = 10/240) during lockdown (March 2020-February 2021) and increased to 12.1% (95% CI, 9.8%-14.7%, n = 87/719) with the reopening of society (March 2021-December 2021; = .0009).

Conclusions: Pneumococcal carriage prevalence declined significantly during pandemic mitigation measures and rebounded to prepandemic levels as measures were lifted.

Background: Streptococcus pneumoniae is an important cause of pneumonia, sepsis, and meningitis, which are leading causes of child mortality. Pneumococcal conjugate vaccines (PCVs) protect against disease and nasopharyngeal colonization with vaccine serotypes, reducing transmission to and among unvaccinated individuals. Mozambique introduced 10-valent PCV (PCV10) in 2013.

Background: Pneumococcal conjugate vaccines (PCV) reduced invasive disease, but the overall prevalence of pneumococcal nasopharyngeal colonization among children has not changed significantly. Our knowledge of which serotypes, once colonized, hold a higher likelihood to cause invasive disease is limited.

Methods: Serotype-specific invasive capacity (IC) of Streptococcus pneumoniae was estimated using an enhanced population-based invasive pneumococcal disease (IPD) surveillance in children <7 years of age in Massachusetts and surveillance of nasopharyngeal (NP) colonization in selected Massachusetts communities in corresponding respiratory seasons.

Microbiology reference laboratories perform a crucial role within public health systems. This role was especially evident during the COVID-19 pandemic. In this Viewpoint, we emphasise the importance of microbiology reference laboratories and highlight the types of digital data and expertise they provide, which benefit national and international public health.

Article Synopsis
  • The study investigates the prevalence of nasopharyngeal Streptococcus pneumoniae carriage (NSPC) in infants under two years, focusing on differences by vaccine types and country income levels.
  • A systematic review of 49 articles revealed a highest NSPC prevalence in infants aged 4 to 6 months and 7 to 9 months, particularly elevated in low-income countries.
  • The findings stress the importance of monitoring NSPC trends, especially non-vaccine serotypes, to inform vaccination strategies and reduce pneumococcal disease burden in infants.
