The article is correct. Infection is the process of a virus entering a cell. Disease is the virus's cumulative effect on the body due to the infection.
Since the protein (LRRC15) mentioned in the article binds to the virus, making it impossible for the virus to infect the cells, it does indeed block infection.
It's an infection of sars-cov-2 which if left unchecked can cause COVID-19 disease. But unfortunately that proper notation train left the station a few years ago.
Which makes the headline even more confusing. How can you be infected by a disease? The article gets it right, even if the headline doesn't, SARS-CoV-2 infection.
