How many people have died of Swine Flu in the UK without underlying complications?

According to the UK Health Security Agency (UKHSA), as of 21 October 2010, there have been 457 deaths in the UK from influenza A (H1N1)pdm09, commonly known as swine flu, where the underlying cause of death was influenza.

Of these deaths, 38% had no underlying medical conditions. This means that approximately 175 people in the UK have died of swine flu without underlying complications.

It's important to note that these figures are from 2010, and the situation may have changed since then. For the most up-to-date information, I recommend checking the UKHSA website.
