A study from Thailand documents a case of a veterinarian catching COVID after an infected cat sneezed on her.
The clue is in your poo. Two experts explain the history and science behind wastewater surveillance.
Intuitively, we would assume that subsequent infections should be less severe. But this won’t always be the case.
The FDA’s authorization of COVID-19 shots for children ages 6 months to 4 years will bring relief for millions of parents. Pending CDC endorsement, shots for this group will be available within days.
‘Hybrid immunity’ is the term for immunity acquired from both prior infection and vaccination.
The COVID-19 pandemic has seen an increase in wastewater testing to monitor the spread of the virus. But historical cases show that targeted surveillance can further marginalize vulnerable populations.
Waiving patent rights on COVID-19 vaccines and drugs is still crucial to ensure access globally, but the waiver on the table at the June World Trade Organization meeting doesn’t do the job.
Achieving herd immunity via vaccination was always going to be a hard ask. Now it’s mathematically impossible.
The COVID-19 vaccines continue to be effective against severe illness leading to hospitalization and death in all age groups, including children ages 5 to 11.
Scientists are working on intranasal COVID vaccines. Not only are these vaccines delivered differently – but they also target a different part of our immune system.
With the right training, dogs can sniff out more than 90% of COVID cases.
Even taking into account people who have had COVID but didn’t know it, there’s still likely to be a group of people who have never been infected.
Scientists exploring the possibility of an animal origin for Covid-19 are still investigating the missing link between bats and human beings.
With the relaxation of mask-wearing mandates, there’s even more need to know how much over-the-counter tests help.
The direct effects of COVID-19 disease on pregnant women, newborns and children are acknowledged. But the indirect effects of the pandemic have been equally devastating.
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.
It’s hard to keep up. But new Omicron sub-variants are emerging that may lead to reinfections and another spike in cases.
Over 800 sites across the US report coronavirus data from sewage to the CDC. Here’s how this kind of surveillance system works and what it can and can’t tell you.
Existing coronavirus vaccines are not as effective against newer variants of the virus. Two vaccine experts explain how new vaccines currently in development will likely offer better protection.
