Influenza RNA sequences from three sets of lungs preserved in formalin since 1918 provide new insights into the deadly pandemic.

A modeling study of boarding behavior finds filling the plane from back to front extends the close contact time between passengers and therefore increases the risks posed by air travel.

Scientists at the US CDC report no red flags in a preliminary analysis of the safety of Pfizer/BioNTech’s and Moderna’s mRNA-based immunizations among expectant mothers.

Researchers involved in a long-term project to identify viruses of concern have now assessed the risk factors that could help forecast which pathogens are the most likely to spillover from wildlife to people.

A review of hundreds of cases finds that only a minority of patients noted being sick with a coronavirus infection prior to developing the severe inflammatory condition.

Martha Nelson of the National Institute of Allergy and Infectious Diseases talks about the need to balance data sharing and patient privacy concerns when tracking the spread of variants.

A review article containing contested claims about the tropical medicine drug as a COVID-19 treatment was listed as “provisionally accepted” on the journal’s website before being removed this week.

Death rates among blood cancer patients who contract COVID-19 are higher than for those with other cancers, pointing to impaired immunity that makes it hard to overcome the virus.

The woman may have had a link to another person, who was married to an Ebola survivor and who died a few days previously in Democratic Republic of Congo.

A study of people in Sierra Leone suggests that the virus can lie in hiding from the immune system before re-emerging later and sparking a new response—although researchers didn’t examine whether this could make people infectious again.

Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.

As politicians try to schedule an end to the pandemic, scientists say the virus will stick around as an endemic disease similar to the common cold.

From 2017 to 2018, cancer deaths dropped by 2.4 percent, the largest single-year improvement recorded in 70 years of American Cancer Society annual cancer reports.

Some researchers have turned their focus to artificial intelligence to study an underused symptom common to most respiratory pathogens—cough.

The so-called 614G mutation in the viral spike protein does not appear to cause more severe cases of COVID-19, but multiple studies indicate that it could be more contagious.

J. Michael Lane was the director of the CDC’s successful program to eradicate smallpox.

The authors of a new analysis conclude that tens of thousands of lives could have been saved with a more coordinated national response to the coronavirus.

Lab and field experiments indicate that aquatic environments could act as reservoirs for the pathogens, which typically do not represent a direct risk to humans.

The four factors that drive contagion
