Introduction
The global coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on public health worldwide, leading to widespread changes in human behavior and psychological responses to the virus (Wang et al. and Alkhamees et al.) [1,2].Understanding these changes is essential for developing effective public health interventions.This study aims to compare two groups of YouTube videos posted during different periods of the pandemic, with a focus on examining the evolution of people's emotions, behaviors, and precautions (Basch et al. and Basch et al.) [3,4].Specifically, this research seeks to investigate how people's attitudes and actions toward COVID-19 have been influenced by their perceptions of the virus's transmission, symptomatology, and prevention measures (Dryhurst et al. and Abu et al.) [5,6].By analyzing and comparing the titles of these videos, we aim to gain insights into the evolving public responses to the pandemic such as in Gozzi et al. and Pobiruchin et al. [7,8] and how they may impact future public health interventions (Holmes et al. and Chong et al.) [9,10].

Materials And Methods
This observational study aims to compare changes in people's emotions, behaviors, and precautions related to COVID-19 at the initial and conclusion periods of the pandemic by analyzing two groups of YouTube videos.The first group of videos were those posted during the initial period of the pandemic, between January and June 2020, while the second group included videos posted two years later, between January and June 2022.The keyword "COVID-19" was used to filter both groups of videos and relevant titles were identified for analysis.The titles were then systematically reviewed and compared to identify patterns of change in people's responses to the pandemic.To ensure a rigorous and objective analysis, an algorithm was used to interpret and categorize the identified patterns.First, we defined the study's research question: To investigate changes in people's emotions, behaviors, and precautions related to COVID-19 in the initial and end stages of the pandemic, with a focus on examining the evolution of people's attitudes and actions toward COVID-19 and how they may impact future public health interventions.Second, we identified the study's target population: YouTube videos related to COVID-19.Then, we determined the inclusion criteria for the videos, as the videos should have been posted during two different periods: the initial period of the pandemic (between January and June 2020) and two years later (between January and June 2022), the videos must contain the keyword "COVID-19" in their titles, and the videos must be in the English language.After determining the inclusion criteria, the search for relevant videos using YouTube's search engine was started, using the inclusion criteria defined above, and collecting the titles of the relevant videos.The titles of the videos were systematically reviewed and compared to identify patterns of change in people's responses to COVID-19.Then, the videos were categorized into the identified patterns.After all the patterns were analyzed to gain insights into the evolving public responses to the pandemic and how they may impact future public health interventions, we interpreted the findings and drew conclusions based on the analysis of the YouTube video titles.Finally, the study was written in an article format, including an introduction, materials and methods, results, and discussion sections.

Results
The analysis of the first group of YouTube videos showed that the titles reflected people's initial anxiety and perplexity about the virus.

We also found that the percentage of videos in the first group with titles related to basic prevention measures, such as mask-wearing and social distancing, was significantly higher (approximately 70%) as compared to the second group, where these topics accounted for only about 30% of the titles.In contrast, titles related to vaccination and travel precautions increased from approximately 10% in the first group to around 50% in the second group.

Discussion
The present study compared two groups of YouTube videos posted during different periods of the COVID-19 pandemic to gain insights into the evolution of people's emotions, behaviors, and precautions.The analysis of the video titles showed that there was a shift from a general lack of understanding and fear about the virus to a more nuanced approach to prevention and management.This shift was characterized by a focus on vaccination and travel-related precautions in the second group of videos, in contrast to the emphasis on basic prevention measures in the first group.The findings of this study have important implications for public health interventions and policies aimed at mitigating the impact of COVID-19 and other pandemics.
One of the key findings of this study was the increased emphasis on vaccination in the second group of YouTube videos.This reflects a growing recognition of the importance of vaccination in controlling the spread of the virus.Vaccination has been shown to be an effective tool in preventing COVID-19 infections and reducing the severity of illness [11].Therefore, public health campaigns aimed at increasing vaccine uptake are crucial in controlling the pandemic [12].
Another important finding of this study was the shift in focus toward travel-related precautions in the second group of videos.The impact of the pandemic on travel has been significant, and the travel industry has been greatly affected [13].The findings of this study suggest that people are becoming more aware of the risks associated with travel and are taking necessary precautions.It is essential to continue educating the public on safe travel practices and to implement effective measures to reduce the spread of the virus during travel [14].
The results of this study also highlight the importance of public health education efforts in promoting evidence-based prevention and management strategies for COVID-19.The initial group of YouTube videos showed a general lack of understanding and fear regarding the virus, leading to an emphasis on basic prevention measures such as mask-wearing and social distancing.However, as the pandemic progressed, people became more informed and educated about the virus, leading to a shift toward more nuanced approaches to prevention and management.
Furthermore, this study demonstrates the potential of social media platforms, such as YouTube, as a tool for monitoring and understanding public responses to pandemics.Social media has been shown to play a significant role in shaping public perceptions and behaviors towards health-related issues [15].Therefore, public health officials can leverage social media platforms to disseminate accurate information, address misconceptions and concerns, and promote evidence-based prevention and management strategies for COVID-19.

Limitations of our study
A lack of generalizability, as we only analyzed YouTube videos posted in the English language and could not capture the full range of attitudes and behaviors toward COVID-19.Additionally, analyzing only video titles may not capture the full context and nuances of the videos' content.YouTube videos are often created by individuals and may not be representative of the broader population.Additionally, YouTube's algorithms and search results can be influenced by factors like user behavior and advertising, which could affect the types of videos that are seen and shared.

Conclusions
The present study highlights the significant changes in people's emotions, behaviors, and precautions toward COVID-19 during different periods of the pandemic.By analyzing the titles of YouTube videos posted during two different periods, we have identified a shift from a general lack of understanding and fear about the virus to a more nuanced approach to prevention and management.This shift is characterized by a focus on vaccination and travel-related precautions in the second group of videos, in contrast to the emphasis on basic prevention measures in the first group.These findings can inform public health policies and interventions aimed at mitigating the impact of COVID-19 and other pandemics.Furthermore, this study highlights the potential of social media platforms, such as YouTube, as a tool for monitoring and understanding public responses to pandemics and other health crises.As the COVID-19 pandemic continues to evolve, continued analysis of public responses and behaviors can help inform effective public health interventions and policies.
