Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.
Health officials say the new case of polio in New York state and the presence of poliovirus in the municipal wastewater suggests that hundreds more could already be infected with the disease.
Coinfections with bacteria can make viral infections even deadlier. Researchers have identified a protein in immune cells that may play a role in fighting both types of pathogens.
There are two approved monkeypox vaccines in the US. Both use a related poxvirus called vaccinia to produce an immune response that protects against smallpox and monkeypox.
While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.
Sepsis onset can be difficult to recognize, in part because its symptoms can mimic those of many other conditions. A treatment delay of even a few hours can make the difference between life and death.
Your blood can hold a record of past illnesses. That information can reveal how many people have had a certain infection – like 58% of Americans having had COVID-19 by the end of February 2022.
Classical antibiotics that directly kill pathogens are prone to elicit drug-resistance. Targeting host enzymes required for pathogen survival offers can limit the emergence of resistance.
The two types of COVID-19 tests – antigen and PCR – work in very different ways, which is why one is fast but less accurate and the other is slow and precise.
Ivermectin has been a lifesaving drug for people with parasitic infections like river blindness and strongyloidiasis. But taking it for COVID-19 may result in the opposite effect.
A centralized reporting system for laboratory incidents involving dangerous pathogens in biological research does not exist in the US or internationally.

De nombreux pays africains ont acquis beaucoup d'xpériences en matière de gestion de épidémies de fièvres hémorragiques virales qu'ils peuvent appliquer à celle du virus à Marburg.
As Los Angeles County again mandates masking indoors – even for the fully vaccinated – local health officials in the U.S. are closely eyeing their own COVID-19 vaccination and infection rates.
