Around 400 people were hospitalized out of the over 1,600 suspected cases, Cordova said.

The authorities are trying to confirm how many were caused by the deadly new virus strain, which has broken out in as many as seven other countries, Cordova said.

Mexican health officials reported 86 deaths earlier Sunday and nearly 1,400 sickened.
