Phages, or viruses that infect bacteria, can lie dormant within chromosomes until they’re triggered to replicate and burst out of their hosts.
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.
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.
A COVID-19 vaccine does not cause infertility – but it can protect you from the dangerous complications of contracting the virus.
Researchers are piecing together clues to better understand the puzzling array of symptoms in those who never seem to fully recover from COVID-19.
COVID vaccines don’t contain any live virus to shed. Here’s the science to put the myth of viral shedding after the COVID vaccine to bed.
COVID-19 vaccination produces a more consistent immune response than a past infection. With the delta variant, the difference in protection may be even greater.
Simulations of classrooms and offices can help determine the safest configurations to reduce the spread of COVID-19.
The COVID-19 vaccines are a smash success. But that doesn’t mean they keep every vaccinated person completely free of the coronavirus.
If you’ve already had the coronavirus and recovered, you might be tempted to give the vaccine a pass. A scientist explains why the shot offers the best protection against future infection.
A new study argues for selective border relaxations. But with COVID-19 more prevalent now than at almost any point in the past, the risk would be substantial.
Communication between programmers and local communities can provide good opportunities in the toilet prototyping process from the beginning of the design process.
Resistant bacteria aren’t the only risk posed by overprescribing antibiotics. A more immediate risk is side-effects and reactions, which a new review shows are surprisingly frequent and often severe.
‘Normal’ body temperature has declined in urban, industrialized settings like the US and UK. Anthropologists find the trend extends to Indigenous people in the Bolivian Amazon – but why?
Widely adopted in the US when pandemic precautions kept people home, telehealth faces a challenge as insurance coverage changes, right when its popularity had surged.
Scientists in the UK and Germany discovered a new doorway that the COVID-19 virus uses to infect human cells. This reveals new therapeutic possibilities for blocking the virus.
Over the approaching holidays, people around the world will want to travel to see friends and family. Getting tested for the coronavirus can make this safer, but testing alone is not a perfect answer.
