Airport screening for viruses misses half of infected travelers but can be improved, says UCLA-led study

In the past decade, the H1N1 virus and Ebola are just two of the diseases whose spread was spurred by international airline travel. Screening passengers at airports, therefore, could be one key method for slowing the global spread of infectious diseases. And although a team lead by UCLA researchers has found that airport screening misses at least half of infected travelers, the scientists say that rate could be improved. Their research was published in eLife, a highly regarded open-access online science journal. The life scientists used a mathematical model to analyze screening for six viruses: the SARS coronavirus, the Ebola virus, the Middle East respiratory syndrome coronavirus, the Marburg virus, Influenza H1N1 and Influenza H7N9. “We found that for diseases with a long incubation period, such as Marburg and Ebola, taking passengers’ temperature to test for fever is particularly ineffective at the start of an epidemic but does pick up more cases as the epidemic stabilizes,” said Katelyn Gostic, a lead author of the study and a UCLA doctoral student in the laboratory of Professor James Lloyd-Smith. “With diseases such as swine flu, which take a shorter time to incubate, fever screening is the most effective method throughout an epidemic.” Depending on the circumstances, airport workers conduct screenings before passengers board their flights, when they land at their destinations, or both. The researchers write that although fever screening on ...

GachonAbstractChytrids have long been recognised as important parasites of microalgae in freshwater systems, able to shape the dynamics of blooms, the gene pool of their host and phytoplankton succession. In the sea however, where the presence of these organisms is erratic and ephemeral, studies concerning chytrids are sparse and confined to metabarcoding surveys or microscopy observations. Despite the scarcity of data, chytrid epi...

AbstractPain management in the pediatric population is complex for many reasons. Mild pain is usually managed quite well with oral acetaminophen or ibuprofen. Situations involving more severe pain often require the use of an opioid, which may be administered by many different routes, depending on clinical necessity. Acute and chronic disease states, as well as the constantly changing maturational process, produce unique challenges at every level of pediatrics in dosing and management of all medications, especially with regard to high-risk opioids. Although there has been significant progress in the understanding of opioid ...

CONCLUSION: emergency nurses perceive their practice during the management of an epidemic expanded in that they shouldered a greater responsibility in the control of infectious diseases. This expansion led to role ambiguity among them. PMID: 31002559 [PubMed - in process]

In this study, we developed a rapid and efficient assay that combines loop-mediated isothermal amplification with lateral flow dipstick (LAMP-LFD) for detection of the Salmonella hilA gene. Compared with PCR and real-time PCR methods, the LAMP-LFD assay has the same specificity and higher sensitivity, and required only 40 min (10 min for LFD detection) at 65 °C. All 52 strains of Salmonella yielded positive results using the LAMP-LFD assay and showed no cross reaction with 37 tested non-Salmonella strains. The detection limit of the LAMP-LFD assay was 13.5 fg/μl (genomic DNA) and 6.7 CFU/mL (cell), which w...
