Portuguese study discovers why some people react to more seriously than others to infection by Covid virus

Investigators at Porto’s i3S (institute of health investigation and innovation) have discovered why some people develop Covid-19 and go on to be very ill, while others don’t.

It’s all in the T-cells, and how they react to initial infection by SARS-CoV-2.

More specifically, it’s all in the T-cells of the people who don’t even exhibit symptoms – the so-called asymptomatic carriers.

The boon of this research is that a) it can give doctors a heads-up as to how a patient’s illness will progress (and give them valuable time to react with treatments), and b) it can be used (in the form of blood plasma treatments) to help those who are worst affected.

Financed under the Iniciativa Research 4 Covid programme of the Portuguese foundation for Science and technology (FCT), the results of this study have been published in the Journal of Immunology. The article can be read in its entirety here, and, say reports, “has already become a ‘top reader’ of the September edition” (which must be out very early…)
