The long-term effects of infection on the immune system have long intrigued John Tsang, a Yale immunobiologist. After the body has faced down a pathogen, does the immune system return to the previous baseline? Or does a single infection change it in ways that alter how it will respond not only to a familiar virus but also to the next new viral or bacterial threat it faces?
Breaking research demonstrates the efficacy of two data analytics-based strategies that clinical labs employed to meet COVID-19 testing demands during the height of the pandemic. These findings, published in the Data Science Issue of AACC’s The Journal of Applied Laboratory Medicine, give labs a blueprint for using data analytics to ensure patient access to testing during future infectious disease outbreaks.

Find out what special pathogens expert Erika Cheung, MSN, RN, CPN, has to say about the disease, which the WHO has declared a public health emergency of international concern. Since May 18, 2022, cases of mpox have been spreading in the United States, including California. On July 23, 2022, the World Health Organization (WHO) declared the current outbreak a public health emergency of international concern.
Artificial intelligence could help doctors dynamically determine safe and effective medication dosing for unstable ICU patients. Predicting the right dose of medication that a critically ill child in the ICU will require in the future is a huge challenge for clinicians. FDA prescribing guidelines generally assume that patients are stable enough so that dosing for a given group is usually unchanged during treatment, but this ‘one size fits all’ approach to medication dosing does not accurately target the condition of each individual patient over time.
A Sudan ebolavirus vaccine and antibody therapeutic tested at Texas Biomedical Research Institute have been sent to Uganda as part of efforts to control the outbreak there.
When it comes to predicting disasters brought on by extreme events (think earthquakes, pandemics or “rogue waves” that could destroy coastal structures), computational modeling faces an almost insurmountable challenge: Statistically speaking, these events are so rare that there’s just not enough data on them to use predictive models to accurately forecast when they’ll happen next.
Perceptions of the causes of illness vary widely across the global population. But now, researchers from Japan have found new information about the perception that individuals with COVID-19 deserved to get infected.
Rutgers researchers hope their genome-assembly tool will spur the development of new treatments for bacterial infections.
Antibiotic resistant bacteria pose of the greatest threats to global public health. New research has the potential to reduce the amount of antibiotics used in the clinic and may pave the way for the discovery of new antibiotics that change growth rate and energy levels in bacteria.
The diagnosis and treatment of long COVID syndrome (LCS) is still very difficult, and there is only little knowledge about the factors causing accompanying symptoms.
The incredibly fast spread of COVID-19 throughout the world brought to light a very important fact: we need better methods to diagnose infectious diseases quickly and efficiently.
Japan’s government has drawn criticism from some of the nation’s researchers following a new analysis that shows Japan has for years been lagging in the field of infectious diseases research, including after the COVID-19 pandemic had hit.

Researchers trained five classification algorithms to create an accurate model to predict COVID-19 test results. Results identify the key symptom features associated with COVID-19 infection and provide a way for rapid screening and cost effective infection detection. Findings reveal that number of days experiencing symptoms such as fever and difficulty breathing play a large role in COVID-19 test results. Findings also show that molecular tests have much narrower post-symptom onset days compared to post-symptom onset days of serology tests. As a result, the molecular test has the lowest positive rate because it measures current infection.
