News Coverage of Face Masks in Australia During the Early COVID-19 Pandemic: Topic Modeling Study

News Coverage of Face Masks in Australia During the Early COVID-19 Pandemic: Topic Modeling Study

The findings suggested that mask-wearing can reduce COVID-19 transmission by up to 85% and is often better with higher-end masks such as N95 and similar respirators [8]. In line with existing supportive evidence on community use of face masks, many countries that historically do not have a mask-wearing culture have initially adopted a mask-wearing policy, while other countries with an established mask-wearing culture have continued to use masks [9].

The Relationship Between Face Mask Use and Face-Touching Frequency in Public Areas: Naturalistic Study

The Relationship Between Face Mask Use and Face-Touching Frequency in Public Areas: Naturalistic Study

Frequency of single touch versus multiple touches shown across subject’s oral activity, touch duration and mask wearing. Mask-wearing style was recorded to observe if subjects were wearing their mask properly, covering their nose and mouth. Subjects who were only covering their mouth with their mask, wearing it as a chin strap, or taking their mask on and off were considered to be not wearing a mask for this study. In Table 4, the frequency of mask style is presented.

Persuasive Messages for Improving Adherence to COVID-19 Prevention Behaviors: Randomized Online Experiment

Persuasive Messages for Improving Adherence to COVID-19 Prevention Behaviors: Randomized Online Experiment

Index variables for intentions to engage in prevention behaviors (pre- and posttreatment) were created by averaging across six items: (1) Limit my physical contact with others when possible, (2) Completely avoid any unnecessary physical contact with others (eg, hugging or handshakes), (3) Avoid crowded indoor spaces, (4) Wear a mask when I leave the house, (5) Wash my hands as much as possible, and (6) Stay home when mildly sick.

The Use of a Health Compliance Monitoring System During the COVID-19 Pandemic in Indonesia: Evaluation Study

The Use of a Health Compliance Monitoring System During the COVID-19 Pandemic in Indonesia: Evaluation Study

Such measures include case isolation, voluntary home quarantine, social distancing, stopping mass gatherings, curfews, travels ban, lockdowns, as well as personal NPIs such as mask wearing, hand washing, and other health precautions. Mask wearing has been proven to be effective in reducing the likelihood of infections [4], yet its efficacy in reducing the risk of transmission is still being evaluated [4].

COVID-19 Health Beliefs Regarding Mask Wearing and Vaccinations on Twitter: Deep Learning Approach

COVID-19 Health Beliefs Regarding Mask Wearing and Vaccinations on Twitter: Deep Learning Approach

The purpose of this study is to investigate health beliefs and cues to action for mask wearing and vaccination using machine learning of COVID-19–related Twitter posts. External cues to action from prominent pandemic declarations (eg, WHO and the CDC) regarding mask wearing and vaccines and prominent examples of displayed preventive behaviors (eg, presidential mask wearing) were explored for possible influence on health beliefs, as explained by HBM constructs.

Exploiting Missing Value Patterns for a Backdoor Attack on Machine Learning Models of Electronic Health Records: Development and Validation Study

Exploiting Missing Value Patterns for a Backdoor Attack on Machine Learning Models of Electronic Health Records: Development and Validation Study

Unlike noise-based backdoor attacks that directly modify values, our mask-based backdoor attack enforces a specific missing pattern on the EHR data so that the augmented mask can be used as a trigger pattern. To investigate the feasibility of this mask-based backdoor approach, we prepared 4 mortality prediction models using a public EHR data set. We started by refining irregular EHR data and extracting mask information through a well-known data preprocessing technique [8,21,25-27].

Social Determinants in Self-Protective Behavior Related to COVID-19: Association Rule–Mining Study

Social Determinants in Self-Protective Behavior Related to COVID-19: Association Rule–Mining Study

For example, if we have responses from 100 subjects in the database and 70 (70%) of them only leave the house with a mask, the support of the answer “only leaves home when extremely necessary and wearing a face covering” is equal to 70/100 = 0.7. Confidence, in turn, measures how likely it is that a person gives a set of question-answers Y, given they gave a set of question-answers X, that is, the conditional probability of Y given X.

Peer Review of “Mask Use to Curtail Influenza in a Post–COVID-19 World: Modeling Study”

Peer Review of “Mask Use to Curtail Influenza in a Post–COVID-19 World: Modeling Study”

This is a peer-review report submitted for the paper “Mask Use to Curtail Influenza in a Post–COVID-19 World: Modeling Study.” This paper [1] investigates how influenza cases can be decreased by the implementation of masks by a varying proportion of the population. It uses previous research and historical case rates by the Centers for Disease Control and Prevention (CDC) to form its model. Overall, this paper’s model is an informative look at a potential scenario for future flu seasons.

Peer Review of “Mask Use to Curtail Influenza in a Post–COVID-19 World: Modeling Study”

Peer Review of “Mask Use to Curtail Influenza in a Post–COVID-19 World: Modeling Study”

This is a peer-review report submitted for the paper “Mask Use to Curtail Influenza in a Post–COVID-19 World: Modeling Study.” The manuscript [1] entitled “Masks in Post COVID-19 World: Better Alternative to Curtailing Influenza?” undertakes the question as to whether the use of masks should continue after the COVID-19 pandemic for influenza. The authors use a susceptible-exposed-infected-recovered model to evaluate mask parameters.
