Hands are frequently contaminated with fecal bacteria and enteric pathogens globally: a systematic review and meta-analysis (Publications)
Enteric pathogen infections are a leading cause of morbidity and mortality globally, with the highest disease burden in low-income countries. Hands act as intermediaries in enteric pathogen transmissi
Nutrition in City Ecosystems (NICE): protocol of a multi-sectoral development project to improve food and nutrition security of secondary city... (Publications)
BACKGROUND: Secondary cities tend to be better linked with local food systems than primate cities, acting as important platforms to trade agricultural produce with rural surrounding. COVID-19, conflic
Long-term exposure to elemental components of fine particulate matter and all-natural and cause-specific mortality in a Danish nationwide... (Publications)
BACKGROUND: Fine particulate matter (PM(2.5)) is a well-recognized risk factor for premature death. However, evidence on which PM(2.5) components are most relevant is unclear. METHODS: We evaluated th
The air and viruses we breathe: assessing the effect the PM2.5 air pollutant has on the burden of COVID-19 (Publications)
Evidence suggests an association between air pollutant exposure and worse outcomes for respiratory viral diseases, like COVID-19. However, does breathing polluted air over many years affect the suscep
Health service quality in 2929 facilities in six low-income and middle-income countries: a positive deviance analysis (Publications)
BACKGROUND: Primary care is of insufficient quality in many low-income and middle-income countries. Some health facilities perform better than others despite operating in similar contexts, although th
Antibody and B cell responses to SARS-CoV-2 infection and vaccination (Publications)
Antibodies, and the B cell and plasma cell populations responsible for their production, are key components of the human immune system's response to SARS-CoV-2, which has caused the coronavirus diseas
Human B cell clonal expansion and convergent antibody responses to SARS-CoV-2 (Publications)
B cells are critical for the production of antibodies and protective immunity to viruses. Here we show that patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who deve
Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) seroprevalence in healthcare personnel in northern California early in the coronavirus... (Publications)
OBJECTIVE: We assessed the magnitude of unidentified coronavirus disease 2019 (COVID-19) in our healthcare personnel (HCP) early in the COVID-19 pandemic, and we evaluated risk factors for infection t
Defining the features and duration of antibody responses to SARS-CoV-2 infection associated with disease severity and outcome (Publications)
SARS-CoV-2-specific antibodies, particularly those preventing viral spike receptor binding domain (RBD) interaction with host angiotensin-converting enzyme 2 (ACE2) receptor, can neutralize the virus.
