Geneva, Aug 29 (Xinhua) Over 2,100 people worldwide have died from the influenza A (H1N1) since the virus was identified in April, the World Health Organization (WHO) said Friday.

All the six WHO regions have reported deaths from the pandemic, with the Americas reporting the largest death number of 1,876, the UN agency said in a latest update of the situation.

In southeast Asia, 139 deaths were recorded, followed by Europe with at least 85 deaths. Deaths in the West Pacific, Africa and East Mediterranean stand at 64, 11 and 10 respectively.

The total number of lab confirmed swine flu cases reported worldwide is 209,438, but this actually understates the real number of cases as countries are no longer required to test and report individual cases, the WHO said.

The WHO warned that the H1N1 pandemic virus 'has rapidly established itself and is now the dominant influenza strain in most parts of the world.
