Dr Ravi, do you know if studies have been done in
Singapore to confirm whether their reported 382-
nucleotide deletion strain is attenuated?
Dr. Ravi: 382-nucleotide deletion is a huge deletion, whether it is attenuated or not, we are
not sure. We do have deletion, but our deletion is very short, it is about 50 nucleotides in one
particular case, which results in 5 amino acid deletions. I’m not too sure, because 382-
nucleotide deletion is huge, hence I am not too sure if it is attenuated or not. Having a 382-
nucleotide deletion is very unusual hence more data is needed.
