In the sentence
The first documented WNV case in Kerala was in Alappuzha in 2011, with the numbers then growing.
What does then mean in this sentence?
What I think is-
Here then is used as an adverb that refers to a particular time.I interpret it this way-
The first documented WNV case in Kerala was in Alappuzha in 2011, and the population of this virus was rising at that time(in 2011).
But I am not sure if I am correct. Help me understand it better.
Thanks in advance......
