Once a Plaga egg hatches, it's nearly impossible to remove it from the body. But if it's before it hatches, then it can be neutralized by medication.

If it does hatch you might be able to get it out by surgery before it turns to an adult. But it won't be easy. There's a high chance you won't survive the operation.

As far as I know the girl was injected with the egg before you. Her time is ticking. You should prepare yourself for the worst case scenario.

「プラーガ」の卵はふ化する前なら薬で除去できるけど、一旦成長を始めたものは無理ね。
成体になる前に外科手術で取り除く事ができれば、助かるかもしれないけど、成功の確率は低いと思うわ。

たぶん彼女の方が先にやられると思うけど、対処法がない場合どうするか、覚悟はしておきなさい。

Analysis[]

After Leon exits the underground caves, Ada leaves this note to remind him of using the drugs that Luis Sera stole to delay the growth of the Las Plagas inside one's body. The only other solution would be the radiation treatment that may kill Leon and Ashley. It also warns it is only a matter of time before Ashley gets fully infected by the Las Plagas.
