Susceptible host of Swine Flu

Answer 1

Yes. An epidemic refers to a disproportionatly large population infected with the same disease. A pandemic is a globally infectious disease that started as an epidemic. The World Health Orginization is currently categorizing this as an epidemic, but plans to upgrage the threat to that of pandemic proportions are coming soon.

Answer 2

Wikipedia keeps a daily tally of suspect and confirmed cases and confirmed death by Swine Flu. It is not an easy task. See related links. There is additional confusion since Mexico is no longer reporting suspect cases. The US definition of suspect is, that the person has been in a location where swine flu is thought to be present, and has flu like symptoms. Note the various maps showing incidence of the disease. Google identifies them as points, and Wikipedia colors in the entire country as either having only suspect cases, confirmed cases, or confirmed cases and deaths. The entire US in black because there have been two confirmed deaths.

Answer 3

Since the daily and weekly counts required by the CDC, WHO, and national health departments of most nations have stopped after the pandemic was declared over, there is no way to know how many, especially since there are still ongoing cases scattered around the world even as of early 2012.

The treatment is the same as for other types of flu, so there is no need for testing to determine what form of flu someone has. For this reason, there is no definite count possible on cases of this type of flu any more.

Estimation of unreported/untested cases in the US, based on reported cases:

Updated Estimates from April 2009 - January 16, 2010:

On February 12, 2010, CDC updated the estimates to include the time period from April 2009 through January 16, 2010.

* CDC estimates that between about 183,000 and 378,000 H1N1-related hospitalizations occurred between April 2009 and January 16, 2010. The mid-level in this range is about 257,000 2009 H1N1-related hospitalizations.

* CDC estimates that between about 8,330 and 17,160 2009 H1N1-related deaths occurred between April 2009 and January 16, 2010. The mid-level in this range is about 11,690 2009 H1N1-related deaths."

Situation Update from CDC:

7/15/2010

According to the final FluView for the 2009-2010 influenza season (May 16-22, 2010), flu activity in the United States declined again from the previous week and is about the same as what is normally seen during the summer in the United States. Only a small number of influenza viruses are being reported, most of which are 2009 H1N1. Flu is unpredictable, but sporadic cases of flu, caused by either 2009 H1N1 or seasonal flu viruses, will likely continue to occur throughout the summer in the United States.

Internationally, 2009 H1N1 viruses are still circulating, including in the Southern Hemisphere, which is entering its flu season

Situation Update from WHO:

7/9/2010

2009 H1N1 continues to actively circulate in certain areas of the tropics, including the Caribbean, West Africa, and South and Southeast Asia. In the Southern Hemisphere, influenza A (H3N2) viruses are currently co-circulating with 2009 H1N1. In the Northern Hemisphere, the number of influenza B viruses detected has exceeded reports of influenza A.

Influenza type B and A (H3N2) viruses have been detected in South Africa at an increasing rate. Low levels of influenza-like illness (ILI) have been reported from several Southern Hemisphere countries, including Australia, New Zealand, Chile and

Argentina. 2009 H1N1 and A (H3N2) viruses are currently co-circulating in certain Caribbean, Central America, and Southeast Asia countries. 2009 H1N1 is actively circulating in Southern and Western regions of India and Western regions of Africa. In

Bangladesh, the seasonal influenza activity is shifting from 2009 H1N1 to influenza type B. Influenza type B continues to actively circulate in central and southern regions of Africa.
