Cited by 40 •
2018
This manuscript describes the Research Prioritization by Affected Communities (RPAC) protocol and findings from its use with women at risk for preterm birth. Using the protocol, women identified and prioritized their unanswered questions about pregnancy, birth and neonatal care aimed at influencing research priority setting by funders and researchers.

Public Relations (PR) is a strategic communication process that builds mutually beneficial relationships between organizations and the public. It's about influencing, engaging, and building a relationship with key stakeholders to shape and frame the public perception of an organization. PR can be used to protect, enhance, or build reputations through the media, social media, or self-produced communications. A good PR campaign can provide credibility and enhance the organization's reputation by...

Public relations (PR) tools are various methods used by organizations to maintain a positive image and foster a strong relationship with the public. Here are some of the most commonly used PR tools: Press Releases: which are official statements sent to news media to provide information, announce events, clarify issues, and shape public perception. Media kits: that include a company profile, fact sheets, press releases, executive bios, images, and other relevant information. It's a go-to...

Biomarkers are directly-measured biological indicators of disease or health. In population and social sciences, biomarkers need to be easy to obtain, transport, and analyze. Dried Blood Spot (DBS) collection meets this need, can be collected in the field with high response rates and analyzed for a variety of biomarkers.

Important Public Goods

Public goods are services or resources provided primarily by the government because private companies often do not have an incentive to supply them at socially efficient levels. These goods are both non-excludable, meaning that people cannot be prevented from using them, and non-rivalrous, meaning that one person's use does not reduce their availability for others. If private firms are unable to economically prevent multiple, non-paying consumers from consuming their goods, then some consumers...
FAQs
These factors can amplify one another rather than operate independently. A frequent or intense exposure may increase the chance of infection, while limited immune protection can make infection more likely or worsen its consequences. The expected severity of outcomes then helps determine whether a hazard requires broad population measures or focused protection for particularly susceptible groups.
Pathogens that evade host defenses may remain capable of entering or spreading within a population despite immune barriers. Risk can also rise when the infectious challenge overwhelms those defenses. Assessing immune protection therefore adds biological context to transmission estimates and helps explain why the same exposure may produce different consequences among individuals or communities.
The suspected route determines which exposures need investigation and which control measures are relevant. Respiratory droplets, contaminated materials, vectors, and close contact create different opportunities for pathogen movement between people or environments. Linking surveillance findings to these routes helps investigators interpret patterns of spread and select interventions that address the likely source of exposure.
Each approach contributes different evidence. Disease surveillance follows patterns in affected populations, laboratory testing supplies information about infection, and epidemiological modeling helps examine how transmission may develop. Combining them provides a stronger basis for estimating risk than relying on one source alone, while analysis of immune protection adds context about population vulnerability and expected outcomes.
Assessment begins by identifying the hazard and examining how people may be exposed. Investigators then consider susceptibility, the severity of possible outcomes, evidence from surveillance and laboratory testing, transmission patterns, and available immune protection. Epidemiological modeling can help interpret these findings, producing evidence that supports proportionate prevention, response, and protection strategies.
Findings can guide vaccination strategies when analysis identifies populations needing stronger or more targeted protection. They can also support infection-control measures when transmission routes or affected groups become clearer. Using evidence from surveillance, testing, immune analysis, and modeling allows decision-makers to connect preventive actions with the specific conditions driving risk.
During an outbreak, assessment clarifies how a pathogen is affecting individuals or communities and which factors are sustaining concern. This evidence can inform response measures and broader health policy, including decisions about infection control and vaccination. It also helps prioritize resources for populations whose susceptibility or potential outcomes indicate a need for targeted protection.
Analysis of immune protection can indicate whether population defenses are sufficient to limit the consequences of pathogen exposure. When protection is uneven or inadequate, risk assessment can identify groups that may require targeted measures. In immunology and infection research, this connects laboratory and epidemiological evidence with practical decisions about prevention, outbreak response, and policy.
