I have heard the following sentences in a Slow German podcast:
Jetzt im Winter sind einfach viele Viren unterwegs. In der Schule haben die Kinder viel Kontakt zueinander. Da stecken sie sich dann halt auch an.
DeepL translator translates the last sentence as "That's where they get infected", but I'm unable to see how it got to this meaning.
- Does "da sich stecken" mean "to get oneself into there", "to go there" ?
- What is the subject of "anhalten" in the second clause? Does this verb mean "to stop", "to bring to a halt" or something else in this context?
- Is "auch" a modal particle in this context ?
