Timeline of George H.W. Bush's recent medical issues

HOUSTON, Texas (KTRK) -- President George H.W. Bush faces his latest medical episode, which was described by his spokesperson as an infection that spread to his blood.

In recent years, the 93-year-old Bush has been in and out of the hospital for various ailments.

Bush was diagnosed with a form of Parkinson's disease that has forced him to use a motorized scooter or a wheelchair for mobility.

Over Christmas in 2012, he was admitted into a Houston intensive care for a bronchitis-related cough and other issues.

For about a week in December 2014, he spent time in the hospital for shortness of breath.
