2025
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats. Natural Killer Cells: The Fast Responders NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

A method to preserve, detect and sequence RNA from Avian Influenza Viruses was validated and extended using natural faecal samples from birds. This technique removes the necessity of maintaining a cool chain and handling of infectious viruses and can be applied in a 96-well high-throughput setup.
FAQs
A reported event is treated as a concern to assess, not automatic proof that an intervention caused harm. Safety surveillance combines adverse event reporting with clinical, epidemiologic, and healthcare data to examine whether an association exists. This approach supports careful investigation and helps distinguish suspected risks from conclusions strong enough to guide action.
Each data source contributes a different perspective on possible risk. Reports can identify suspected events, while clinical, epidemiologic, and healthcare data support assessment of whether the event is associated with treatment and how risk changes over time. Together, these sources provide a broader basis for investigating safety concerns than any one source alone.
Tracking risk over time helps show whether a suspected concern is emerging, persisting, or changing after an intervention reaches patients. This longitudinal view supports continued investigation and can reveal when prescribing information or risk-minimization measures may need review. It also keeps safety assessment connected to actual use in routine clinical practice rather than a single observation.
The process begins with adverse event reporting and review of relevant clinical, epidemiologic, and healthcare information. Investigators then assess whether the event may be associated with the treatment and track the risk over time. Findings can lead to further evaluation, updates to prescribing information, or risk-minimization measures, depending on what the evidence shows.
They use the findings when evidence about a possible treatment-related harm needs to inform practice or oversight. Regulatory agencies may update prescribing information, while healthcare professionals can incorporate emerging safety information into treatment decisions. Risk-minimization measures may also be implemented when needed, helping align routine clinical use with the best available understanding of potential risks.
Clinical trials provide evidence during structured evaluation, whereas surveillance follows medicines and other interventions as patients receive them in routine practice. By examining adverse events alongside clinical, epidemiologic, and healthcare data, it can identify or assess concerns that require continued observation. This added context supports treatment decisions beyond the trial setting.
