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.
Phages can sense bacterial DNA damage, which triggers them to replicate and jump ship.

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.
Investigators in Florida traced a listeria outbreak to ice cream.

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.
The Jynneos monkeypox vaccine provides strong protection against infection but is in short supply.

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.
The immune system usually stays dormant in the lungs in times of health.

These infections require medical attention right away.
Sepsis begins with infection by bacteria or a virus. This panoramic ilustration inside a blood vessel shows rod-shaped bacteria, red blood cells and immune cells called leukocytes.

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.
Researchers can test blood samples taken for other reasons to see if patients have previously had COVID-19.

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.
While ivermectin was originally used to treat river blindness, it has also been repurposed to treat other human parasitic infections.

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.
Some institutions publish information about their mishaps, while others do not.

A COVID-19 vaccine does not cause infertility – but it can protect you from the dangerous complications of contracting the virus.
People suffering from long-term effects of COVID-19 face uncertainty about the nature of their symptoms and how long they might last.
