Background: With the advent of the COVID-19 pandemic, pregnant women may turn to online information searches regarding COVID-19 and COVID-19 vaccination. Objective: We aimed to determine global online interest in COVID-19 infection and COVID-19 vaccination in pregnancy. Materials and Methods: We utilized Google Trends data to determine the global search volume index (SVI) for the search terms “COVID-19 in pregnancy” and “COVID vaccine pregnancy” from January 1, 2020, to February 12, 2022, and ranked the top 15 search queries via their individual SVIs to assess the worldwide distribution of interest. Using Pearson correlation, we correlated several economic and pandemic-related country-specific data with the SVIs for the two search terms, while we utilized a one-way analysis of variance to country income groups with the SVIs using ANOVA. Significant correlations were denoted with P < 0.05. Results: SVI for “COVID-19” in pregnancy showed a minimal and nonsignificant downward trend in 2022. SVI for this search term was positively correlated with the SVI for “COVID vaccine pregnancy” (P < 0.05). On the other hand, SVI for “COVID vaccine in pregnancy” showed an exponential decline from November 2020 to 2022. SVI for this search term was also negatively correlated with deaths per 100,000 cases (P < 0.05). Although this was nonsignificant, high-income countries showed higher online interest with the two search terms than low- to low-middle-income countries. There were no significant correlations among specific economic and pandemic-related country-specific data and SVI for both search terms. Conclusion We observed a constant online interest in COVID-19 in pregnancy during the time period of the study, which may reflect the watchful engagement of people in the absence of face-to-face physician consultations. Peak online interest in COVID-19 vaccine in pregnancy declined steadily, which may reflect either vaccine hesitancy or an increase in public knowledge of COVID-19 vaccines. High-income countries have apparently higher online interest in COVID-19 vaccines, which may be due to access to early mass administration to the general public. These data can be used as a reference regarding future policy-making in the setting of potentially massive public health emergency in the future.

Background: Catalyzed by the coronavirus disease 2019 (COVID-19) pandemic that restricted non-essential travel, awareness of the value of telehealth increased among healthcare providers and consumers. Telerehabilitation, a subset of telehealth and telemedicine, refers explicitly to the remote provision of rehabilitation services. However, since the majority were new to the concept of telerehabilitation, which was commonly interchanged with other related terms (e.g., telehealth, telemedicine, teletherapy, telecare, telepractice, etc.), and relevant internationally recognized guidelines were not available pre-pandemic, many turned to online resources to learn more about it. However, such might create confusion with the terminologies. Objective: This infodemiological study aimed to examine the trends of global online interest in telehealth, telemedicine, telerehabilitation, and related search terms. The authors hypothesized an abrupt rise in stakeholders' awareness regarding the virtual method of delivering or accessing healthcare, including rehabilitation services, during the pandemic. Method: Using Google Trends™, we obtained and analyzed the trends of global online interest in telehealth, telemedicine, telerehabilitation, and other related search terms from 2004 to October 2020. Results: The frequencies of searches for “telehealth,” “telemedicine,” and “telerehabilitation” peaked in March 2020, which coincided with the lockdown in many countries, including the Philippines. The term “telehealth” was more frequently searched in western countries, while “telemedicine” was relatively common in eastern countries. Among the terms synonymous with telerehabilitation, “teletherapy” was most commonly used worldwide, with “teletherapy speech” being the most searched related topic. The Philippines had the most significant number of times the term “telerehabilitation” was searched in the past decade. Conclusion During the COVID-19 pandemic, there is an overall global demand for the acquisition of knowledge related to telehealth, telemedicine, telerehabilitation, and related search terms. Of particular interest, tele rehabilitation, however, varied in terminologies across countries, with “teletherapy” mainly being used worldwide and “telerehabilitation” being primarily searched in the Philippines. Therefore, arriving at a consensus across professional societies and operationally defining different interrelated terms could help streamline our current or future guidelines and programs.
