The subvariant, also known as the Delta Plus variant, is a mutation of the Covid-19 Delta variant. It is a combination of the AY.4 Delta variant and the S:Y145H spike mutation.
The Health Ministry said there was no evidence of spread to the community from the case.
"While its effects are still being studied, AY.4.2 is currently expected to be similar to other Delta subvariants in terms of transmissibility and severity of illness," it added.
The subvariant is classified by the World Health Organisation as a variant of interest, but not a variant of concern.
The BBC reported that according to experts, there was no indication that the AY.4.2 subvariant is more infectious or more dangerous than the Delta, but tests are ongoing.
Data from the GISAID virus reporting database also showed that cases of the subvariant have been reported in the United States, Canada, Australia and parts of Western Europe.
