I think what you're speaking of is the Page Title...the summary text that appears in your web browser's tab heading to remind you what's open in that window. That says "Masks keep us safe. Here's how to use..." I suppose if you're looking for the absolute minimum level of information to get from a newspaper article, the browser tab summary text might be it. Congratulations.

The main headline for the actual article says "Masks work. Now we need to pay attention to when and where, and which kind"

The subhead says "It’s not whether to wear face coverings we should be considering. It’s the specifics about use and type."

The the very first line in the article text says "If we all wear a mask when we’re around others, we’ll all be safer."

The entire article is about the efficacy of masks. It is not a be all and end all article about everything one should do to avoid the spread of Coronavirus. It's about why masks are an effective part of it. NOWHERE in it does it says that masks, by themselves, will make everything all better.
