After nearly 28 years, The Communication Initiative (The CI) Global is entering a new chapter. 

Following a period of transition, the global website has been transferred to the University of the Witwatersrand (Wits) in South Africa, where it will be administered by the Social and Behaviour Change Communication Division. Wits' commitment to social change and justice makes it a trusted steward for The CI's legacy and future. 

On the transfer, co-founder Victoria Martin expressed her pleasure to see this work continue under Wits' leadership, knowing that co-founder Warren Feek (1953–2024) would have felt deep pride in The CI Global's Africa-led direction. 

As Wits, we honour the team and partners who sustained The CI for decades and look forward building from that strong base. This includes co-founders Warren Feek (1953-2024) and Victoria Martin as well as La Iniciativa de Comunicación (CILA), which continues independently at lainiciativadecomunicacion.com with links to The CI Global site. We are also eager to forge new partnerships and entertain new ideas as we consider how best to contribute to social and behaviour change in our rapidly evolving environment.

If you are joining the International Social and Behaviour Change Communication (SBCC) Summit in Panama, please join Wits and CILA on Monday, 22 June, to share your thoughts and suggestion for the relaunch of the Communication Initiative. We will be in Pacifica 5 from 12-1:25 for the Refuel, Reflect, and Renew Lunch Series: The Communication Initiative: celebrating a driving force for Communication for Social Change and the way forward. We will reflect on the legacy of Warren Feek and family in creating the Communication Initiative, consider the contributions of CI over the years and then turn our attention towards the future in this dynamic session. 

If you are unable to join us in Panama, we still want to hear from you. Please contribute your thoughts by following this link: https://redcap.link/CommunicationInitiative2026 or reaching out to ci_surveys@commint.com.

Facemasks and hand hygiene to prevent influenza transmission in households: a cluster randomized trial

0 comments

Cowling, B. J., K. H. Chan, et al. (2009). "Facemasks and hand hygiene to prevent influenza transmission in households: a cluster randomized trial." Ann Intern Med 151(7): 437-446.

BACKGROUND: Few data are available about the effectiveness of nonpharmaceutical interventions for preventing influenza virus transmission.

OBJECTIVE: To investigate whether hand hygiene and use of facemasks prevents household transmission of influenza.

DESIGN: Cluster randomized, controlled trial. Randomization was computer generated; allocation was concealed from treating physicians and clinics and implemented by study nurses at the time of the initial household visit. Participants and personnel administering the interventions were not blinded to group assignment. (ClinicalTrials.gov registration number: NCT00425893)

SETTING: Households in Hong Kong. PATIENTS: 407 people presenting to outpatient clinics with influenza-like illness who were positive for influenza A or B virus by rapid testing (index patients) and 794 household members (contacts) in 259 households.

INTERVENTION: Lifestyle education (control) (134 households), hand hygiene (136 households), or surgical facemasks plus hand hygiene (137 households) for all household members.

MEASUREMENTS: Influenza virus infection in contacts, as confirmed by reverse-transcription polymerase chain reaction (RT-PCR) or diagnosed clinically after 7 days.

RESULTS: Sixty (8%) contacts in the 259 households had RT-PCR-confirmed influenza virus infection in the 7 days after intervention. Hand hygiene with or without facemasks seemed to reduce influenza transmission, but the differences compared with the control group were not significant. In 154 households in which interventions were implemented within 36 hours of symptom onset in the index patient, transmission of RT-PCR-confirmed infection seemed reduced, an effect attributable to fewer infections among participants using facemasks plus hand hygiene (adjusted odds ratio, 0.33 [95% CI, 0.13 to 0.87]). Adherence to interventions varied.

LIMITATION: The delay from index patient symptom onset to intervention and variable adherence may have mitigated intervention effectiveness.

CONCLUSION: Hand hygiene and facemasks seemed to prevent household transmission of influenza virus when implemented within 36 hours of index patient symptom onset. These findings suggest that nonpharmaceutical interventions are important for mitigation of pandemic and interpandemic influenza.
