    The contribution of asymptomatic SARS-CoV-2 infections to transmission on the Diamond Princess cruise ship

    Jon C Emery et al.
    Nearly 75% of SARS-CoV-2 infections on the Diamond Princess were asymptomatic, half were never detected, and asymptomatic infections may have contributed substantially to transmission.

    Single-dose BNT162b2 vaccine protects against asymptomatic SARS-CoV-2 infection

    Nick K Jones et al.
    A fourfold reduction in the rate of asymptomatic SARS-CoV-2 infection in healthcare workers ≥12 days after a single dose of BNT162b2 mRNA COVID-19 vaccine (Pfizer-BioNTech) has been found.

    Asymptomatic Bordetella pertussis infections in a longitudinal cohort of young African infants and their mothers

    Christopher J Gill et al.
    Longitudinal qPCR-based pertussis surveillance of a low-resource African cohort reveals frequent asymptomatic pertussis infections in both young infants and mothers and suggests possible early warning signals for epidemic outbreaks.

    Screening of healthcare workers for SARS-CoV-2 highlights the role of asymptomatic carriage in COVID-19 transmission

    Lucy Rivett et al.
    3% of >1,000 asymptomatic healthcare workers in their workplace tested positive for SARS-CoV-2, suggesting that comprehensive screening programmes are vital to prevent acquisition of COVID-19 in hospitals.

    Impact of asymptomatic Plasmodium falciparum infection on the risk of subsequent symptomatic malaria in a longitudinal cohort in Kenya

    Kelsey M Sumner et al.
    The increased risk for symptomatic malaria following an asymptomatic Plasmodium falciparum infection supports targeting asymptomatic infections as a tool to reduce clinical malaria in high-transmission settings.

    Sex-based differences in clearance of chronic Plasmodium falciparum infection

    Jessica Briggs et al.
    Lower malaria prevalence in females does not appear to be due to lower rates of infection but rather due to faster clearance of asymptomatic infections.

    Saliva TwoStep for rapid detection of asymptomatic SARS-CoV-2 carriers

    Qing Yang et al.
    A quick and portable test makes saliva samples turn yellow when people are carrying SARS-CoV-2, the virus that causes COVID-19.

    Evidence for transmission of COVID-19 prior to symptom onset

    Lauren C Tindale et al.
    Control of COVID-19 will require strong case finding and isolation of exposed individuals because transmission can occur days prior to symptom onset.

    Identifying prostate cancer and its clinical risk in asymptomatic men using machine learning of high dimensional peripheral blood flow cytometric natural killer cell subset phenotyping data

    Simon P Hood et al.
    Diagnosing the presence and clinical significance of prostate cancer can be achieved using AI-based analysis of peripheral blood natural killer (NK) cell subset profiles.

    Potential herd protection against Plasmodium falciparum infections conferred by mass antimalarial drug administrations

    Daniel M Parker et al.
    Given sufficient population adherence, mass drug administration for falciparum malaria can provide group level benefits, also known as ‘herd effects’.
