Zoom saw widespread adoption due to its ease of use and HIPAA-compliant options. Telemedicine platforms prioritized stability and security, and Zoom integrated with healthcare systems to facilitate virtual consultations.
What is the primary purpose of digital contact tracing apps deployed during COVID-19?
To diagnose individuals remotely
To schedule vaccination appointments
To identify and notify individuals who have been exposed to infected persons
To provide teletherapy sessions
Digital contact tracing apps use Bluetooth or GPS data to detect potential exposures and alert users. Their main goal is to interrupt transmission chains by notifying at-risk individuals promptly.
In the context of COVID-19 response, what does "mHealth" stand for?
Mental health
Mobile health
Module health
Medical health
mHealth refers to the delivery of healthcare services and information via mobile devices such as smartphones and tablets. It enables remote monitoring, health education, and patient engagement during the pandemic.
On a COVID-19 dashboard, which metric most directly indicates the average number of people one infected person will infect?
Reproduction number (R)
Vaccination coverage
Hospital bed occupancy
Mortality rate
The reproduction number (R) measures how many new infections are generated by one case. It is crucial for understanding transmission dynamics and assessing control measures.
Which of the following tools is known for visualizing global COVID-19 case data in real time?
Johns Hopkins University COVID-19 Dashboard
Google Maps
Twitter Trends
Slack Channel
The Johns Hopkins University COVID-19 Dashboard aggregates data from multiple sources to display case counts, deaths, and recoveries. It became a standard reference for real-time pandemic monitoring.
What is a key privacy advantage of Bluetooth-based contact tracing over GPS-based tracing?
It provides detailed location history
It makes user identities publicly visible
It requires constant internet streaming
It detects proximity without storing precise location data
Bluetooth-based contact tracing measures proximity events without recording exact GPS coordinates, thereby enhancing user privacy. It only exchanges anonymous tokens between devices, reducing location tracking risks.
Which regulatory change in 2020 significantly improved telemedicine adoption during the pandemic?
Expansion of reimbursement policies for virtual visits
Ban on remote prescribing of medications
Restriction of cross-state medical licensure
Increase in malpractice insurance costs
Many healthcare systems and insurers updated policies to reimburse telemedicine at parity with in-person visits, driving rapid adoption. This policy change reduced financial barriers for providers and patients.
What is the primary clinical limitation of telemedicine in COVID-19 care?
Overuse of hospital resources
Inability to perform hands-on physical examinations
Lack of internet connectivity
Excessive patient travel requirements
Telemedicine cannot fully replace in-person care when a physical exam or procedures are needed. This limitation necessitates in-person follow-up for certain assessments or treatments.
Why is a 7-day moving average used on COVID-19 dashboards?
To count the total number of cases
To smooth out daily reporting fluctuations and highlight trends
To measure vaccine efficacy directly
To estimate mortality risk per age group
A 7-day moving average reduces the impact of daily reporting anomalies like weekend delays. It provides a clearer view of the underlying trend in case counts or hospitalizations.
Which statistical model is commonly used for short-term forecasting of COVID-19 case numbers?
k-means clustering
Linear regression on GDP data
Principal component analysis
ARIMA
ARIMA (AutoRegressive Integrated Moving Average) models are widely used for time series forecasting, including case counts. They account for trends, seasonality, and autoregressive patterns in epidemiological data.
What role do AI-powered symptom checker chatbots play in the COVID-19 response?
They produce vaccines
They replace doctors for all medical decisions
They triage patients by assessing symptoms and recommending next steps
They automatically hospitalize users
Symptom checker chatbots guide users through a series of questions about symptoms and exposures to determine the need for testing or care. They reduce the burden on hotlines and help prioritize healthcare resources.
How do SMS-based surveys support contact tracing efforts?
They replace vaccine distribution
They perform PCR tests remotely
They collect self-reported symptom and exposure information efficiently
They deliver telemedicine video calls
SMS surveys allow public health teams to gather symptom and exposure data directly from individuals. This approach scales outreach and maintains social distancing during follow-up.
Which privacy framework provides guidelines for secure and ethical COVID-19 app development?
HIPAA Privacy Rule
NIST Privacy Framework
GDPR Regulation
ISO 27001
The NIST Privacy Framework outlines principles and best practices for protecting privacy in data processing. It has been referenced to guide the development of contact tracing and health apps during COVID-19 to ensure user data protection.
Which mobile health platform integrates patient monitoring data from wearable devices?
Apple Health
Google Classroom
Uber Health
WhatsApp Business
Apple Health aggregates health data from a variety of sensors and wearables, enabling remote patient monitoring. During the pandemic, it has been used to collect metrics like heart rate and activity levels for telehealth consultations.
What is a major barrier to equitable access to mobile health platforms in underserved populations?
The digital divide and lack of internet access
Overabundance of technical support
Too many app download options
Excessive government subsidies
Many underserved communities have limited broadband or smartphone access, hindering use of mHealth tools. Addressing the digital divide is critical to ensuring equitable telehealth services.
In designing a contact tracing algorithm, what trade-off exists between sensitivity and specificity?
Higher sensitivity reduces missed exposures but increases false positives
Higher sensitivity reduces false positives and false negatives equally
There is no trade-off between sensitivity and specificity
Higher specificity increases both false positives and false negatives
Increasing sensitivity in contact tracing captures more true exposure events but may flag contacts incorrectly, raising false positives. Balancing specificity is essential to avoid overwhelming users and public health systems with unnecessary alerts.
Which technique helps prevent overfitting when building predictive models for COVID-19 spread?
Cross-validation
Increasing number of model parameters
Using only training data without testing
Ignoring model complexity
Cross-validation partitions data into training and testing sets to evaluate model performance on unseen data, reducing overfitting. It ensures generalizability of forecasts to future case trends.
What is an advantage of a decentralized architecture for digital contact tracing apps?
Requires government approval for every data access
Reduces centralized data collection, enhancing user privacy
Ensures all data is stored on a single central server
Makes troubleshooting more complex due to centralization
Decentralized architectures store contact event data on individual devices rather than central servers, limiting exposure of personal data. This approach addresses privacy concerns and can increase user adoption.
If the case doubling time on a dashboard decreases from 14 days to 7 days, what does this imply?
Hospital capacity has doubled
The virus is spreading faster
The virus is slowing down
Testing has become less frequent
A shorter doubling time indicates cases are increasing more rapidly, reflecting accelerated transmission. Monitoring doubling time helps gauge the urgency of public health interventions.
Which advanced analytics method is suitable for real-time anomaly detection in COVID-19 surveillance data?
Ordinary least squares regression
K-nearest neighbors clustering
Principal component analysis
Isolation Forest
Isolation Forest is an unsupervised machine learning algorithm that identifies anomalous data points in real time, useful for flagging unusual spikes in case reports. Unlike regression, it can detect irregular patterns without predefined labels.
