Yes, there’s a typo in the first line. (A couple of letters swapped is usually just a typographical error rather than the writer not knowing how to spell a common word.) It’s not the only problem here.
This young woman was from an ordinary family in the village. She lost her parents in an epidemic and is alone. She now works as a traveling trader.
Why no comma before and in the second sentence? Because even though there are two verbs, lost and is, there’s only one subject, she. It’s not a compound sentence.
