Background: The COVID-19 pandemic has brought new situations that require the effective delivery of health information across the world and it's important to offer clear, consistent, and credible information on the pandemic to mitigate and control the outbreak., Aim: To assess COVID-19 information source, need and trust among the rural community of southwest Ethiopia., Methods: A community-based cross-sectional study design was conducted among 634 rural communities of southwest Ethiopia. The data were collected by interviewing individuals from selected households and analyzed by SPSS version 26. A multivariable logistic regression model was used to assess factors affecting information needs., Results: Radio 484 (76.3%) was mostly used as a source of information for COVID-19, and government 404 (63.7%) and health professionals 345 (57.7%) were trusted. However, only 10 (1.6%) of the participants acquired information from health professionals. Around 395 (62.3%) of the participants needed additional information on COVID-19. Around 230 (58.2%) and 186 (47.1%) of the participants required additional information on cause and sign and symptoms, respectively. Age of < 45 years old (AOR: 2.11, 95% CI: 1.43, 3.12, P < 0.001), and absence of formal education (AOR: 2.00, 95% CI: 1.35, 2.95, P: 0.001) were factors positively affecting the information needs of the participants on COVID-19. Church goers (AOR: 3.24; 95% CI: 2.03, 5.19; P < 0.001), television (AOR: 2.39; 95% CI: 1.63, 3.49; P < 0.001) and social media users (AOR: 4.52; 95% CI: 2.26, 9.04; P < 0.001) as source of information required additional information on COVID-19, and the participants that trusted social media (AOR: 2.52; 95% CI: 1.64, 3.87; P < 0.001) and friends/relatives (AOR: 2.95: 95% CI: 1.51, 5.76; P < 0.001) were also required additional information on COVID-19., Conclusions: The popular sources of COVID-19-related information were radio and television. The participants trusted the government and health professionals on COVID-19. However, less than 2% of the participants had information from health professionals. The majority of the participants wanted to learn more about COVID-19. The areas the participants required additional information include cause and signs and symptoms. Age, educational status, trust in social media, trust in friends, using the church, television and social media as a source were factors associated with information needs., (© 2022. The Author(s).)
