The COVID-19 pandemic impacted immensely in schools worldwide, emphasising the pivotal importance of infectious diseases. This study aims to delineate the teaching of diseases in middle schools, investigating how content and instruction was influenced in the aftermath of the pandemic. Semi-structured individual interviews were conducted with teachers. The analytical method involved thematic analysis. The first analysis concerned teaching content was based on the framework of contagion literacy. The second analysis investigated the teaching approaches through an inductive analysis. The findings suggest that the pandemic had an impact on the biology teaching in relation to infectious diseases. During the pandemic, teaching largely revolved around student-initiated, question-driven discussions about current events related to societal health initiatives within schools, rather than expanding the planned biology curriculum. The main finding is that teachers focused on hygiene and to influence students’ behaviours interactively. The pandemic was not fully exploited by the participating teachers to develop more curriculum-based teaching including functional and critical health literacy perspectives. The study recommends that biology teachers collaborate with school health teams and engage in interdisciplinary work. We also suggest to amend primary science teacher education to meet the need to teach the young people in the event of future pandemics.

The COVID-19 pandemic had an immense impact on communities around the world. We know that new epidemic-prone diseases will emerge in the future. Consequently, it is important to investigate what impact the current pandemic had on school children’s understanding of infectious diseases in order to develop biology education based on that novel understanding. The aim of this study was to explore Swedish middle school (10-12-year-old) pupils’ understanding of infectious diseases and their perceived sources of knowledge. Data was collected through individual semi-structured interviews with fifteen pupils and analysed by thematic coding. Results revealed a great impact of the pandemic on the respondents’ conceptions. Firstly, their notion of infectious diseases based on their idea of COVID-19 was elusive because COVID-19 can manifest very differently. Secondly, the need to care about oneself and others was recognized. Thirdly, the importance of vaccines was recognized, but vaccines were given different roles. Finally, their understanding of infection seems to originate from informal domains such as the news and the Internet, rather than from biology education. One proposal for biology teaching could be to introduce scientific concepts earlier, to pay more attention to differences and similarities between infectious diseases, and to cooperate with other school subjects.

Recently, the COVID-19 pandemic impacted immensely on individuals and societies around the world. This study aimed at delineating Swedish middle school (10?12-year-old) pupils? understanding of bacteria and viruses, thereby illustrating the influence of the pandemic at schools and in society. Data was collected by semi-structured, individual interviews and by asking pupils to draw images. Thematic coding of interview transcripts and content analysis of pupils? annotated drawings were used. The morphology of microorganisms from the drawings was often 'corona-like', with a round shape and with protruding parts. Viruses were commonly considered larger than bacteria, but sometimes also similar in size. Interrelationships between bacteria and viruses were expressed with a superior microorganism. Pupils drew microorganisms as cell-like and never portrayed them as animals or with anthropomorphic features. Viruses were considered to cause a more severe disease than bacteria. Pupils seldomly tethered a specific virus to a specific infectious disease, and often named both (virus and disease) 'corona'. However, when they did make a connection, viruses were considered to cause flu and COVID-19, bacteria to cause cold and plague. In general, these results indicate that viruses received a more pronounced position amongst microorganisms in the minds of pupils in the aftermath of COVID-19.
