Many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell to delirium to a higher risk of stroke. Down the road, will COVID-19 survivors face a wave of cognitive issues?
We're cleaning and washing our hands perhaps more than we ever have before. But suggestions that all this this extra hygiene could weaken our immune systems are unfounded.
Children are at risk of getting sick from coronavirus and need to practice social distancing and mask wearing too.

Research shows that children can become infected with the coronavirus and spread it to others. Though rare, some kids do become severely ill and a few have died from COVID-19.
It's hard to discuss COVID without referring to white blood cells. Here is a primer on the two you need to know about.
Duck decoys lure real ducks within range of hunters. Nanoparticles that look like cells serve as both decoys and hunters to ensnare virus particles.
Nanoparticles dressed up in cell membranes snag SARS-CoV-2 virus particles before they reach human cells.
The cutting-edge tools could greatly expand our understanding of different species' immune systems, and also help humans prepare for future disease outbreaks.
Is coronavirus over in some cities?
There is speculation about whether a population can achieve some sort of immunity to the virus with as little as 20% infected.
For those who have suffered from COVID-19, do their antibodies guarantee immunity from subsequent disease?

If you have had COVID-19 already, are you protected from another bout of the illness? And is the presence of antibodies in your blood a guarantee of immunity?

Just focusing on spike proteins might not offer the complete immunity.
OM85 harnesses molecules extracted from bacteria, and has shown promise in preventing severe respiratory infections. It seems to work by training the immune system.
Reports show that the mortality rate among men with COVID-19 is higher than women.

Why does COVID-19 hit men harder than women? Is the disparity in mortality rates due to male hormones or an underlying difference in the male versus female immune system?

Racism – and the chronic stress it causes – leads to poor health among African Americans. It may change the way genes are expressed, leading to increased levels of dangerous stress hormones.
Antibodies are incredibly good at finding the coronavirus. Antigen tests put them to work.

An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.

Between 10-15% of all cells within the brain are microglia.
'Nanobodies' produced by the llama immune system can neutralise the virus that causes COVID-19.
Immunity passports have been touted as a way to reopen the economy. But there are serious concerns they'll create an incentive to intentionally contract the coronavirus.
Early research has pointed to a link between severe illness with COVID-19 and vitamin D deficiency. But there's more to the story.
Immune cells release proteins called cytokines which alert the rest of the immune system that a virus is present.
We blame the coronavirus for the thousands of deaths, but it is actually a hyperactive immune reaction that is the cause of death. An immunologist explains.
Nearly two million antibody tests imported into Australia can't be used to diagnose COVID-19. But it's difficult to make an antibody test that is specific and sensitive enough.
Figuring out how the immune system responds to and defeats coronavirus is our best way out of the pandemic.
