Swine Flu at the CDC

http://www.cdc.gov/flu/weekly/

this is really hard to read and there's a ton of "spin" in the reporting but just check out the map at the very bottom of the page

this was for the week ending 9/19

you can see how most of the country has widespread flu activity; most of that if not 99% of that activity is the 2009 H1N1 AKA swine flu

the outbreak is happening yet the news doesn't talk about it for some reason; probably because people will naturally ask "why give the vaccine after the danger has passed?"

they are being a little sneaky with the reporting of hospitalizations and deaths from the swine flu since that's limited to confirmed cases ; see at least half the time when you have swine flu you test negative , so we don't get a clear picture of how many people are really infected making it seem like a larger % of the people infected are getting hospitalized or dying

....

Three influenza-associated pediatric deaths were reported to CDC during week 37 (Texas [2] and Virginia). These deaths were associated with 2009 influenza A (H1N1) virus infection, and occurred between August 30 and September 19, 2009. Since September 28, 2008, CDC has received 117 reports of influenza-associated pediatric deaths that occurred during the current influenza season (25 deaths in children less than 2 years, 12 deaths in children 2-4 years, 35 deaths in children 5-11 years, and 45 deaths in individuals 12-17 years). Forty-nine of the 117 deaths were due to 2009 influenza A (H1N1) virus infections, and four of these have occurred since August 30, 2009.
Of the 50 children who had specimens collected for bacterial culture from normally sterile sites, 19 (38.0%) were positive; Staphylococcus aureus was identified in 13 (68.4%) of the 19 children. Six of the S. aureus isolates were sensitive to methicillin and seven were methicillin resistant. Seventeen (89.5%) of the 19 children with bacterial coinfections were five years of age or older and 12 (63.2%) of the 19 children were 12 years of age or older. Nineteen (38.8%) of the 49 children with confirmed 2009 influenza A (H1N1) infection had a specimen collected from a normally sterile site; five (26.3%) of the 19 children had a positive bacterial culture (methicillin sensitive S. aureus [2], methicillin resistant S. aureus [2], and Streptococcus constellatus
).



....

so in the middle of a wide spread outbreak (between August 30 and September 19, 2009) when the population is an unimmune to the swine flu as they can get we had 3 pediatric deaths nationwide

it then goes on to talk about staph bacteria coinfecting children with the flu; our problems with rampant resistant staph infections probably has more to do with the deaths caused from viral infections like the swine flu than the virus itself

our food supply being supersaturated with live stock antibiotics and one of our childhood vaccines (prevnar) exacerbate the antibiotic resistance problem

"The use of the vaccine created an ecological vacuum, and that combined with excessive use of antibiotics to create this new superbug," Pichichero said.

“Being a carrier of MRSA has increased a lot, especially among school-aged kids,” said Lyn Finelli, chief of influenza surveillance at the CDC. “And being colonized may put them at risk for a severe staph aureus infection when they get the flu.”

Whether the current increase in severe community-acquired S. aureus infections, including methicillin-resistant S. aureus (6), is partially caused by the recent introduction of the pneumococcal conjugate vaccine is yet to be determined.

A trial with a 7-valent pneumococcal-conjugate vaccine in children with recurrent acute otitis media showed a shift In pneumococcal colonisation towards non-vaccine serotypes and an Increase In Staphylococcus aureus-related acute otitis media after vaccination. We investigated prevalence and determinants of nasopharyngeal carriage of Streptococcus pneumonlae and S aureus in 3198 healthy children aged 1-19 years. Nasopharyngeal carriage of S pneumonlae was detected In 598 (19%) children, and was affected by age (peak Incidence at 3 years) and day-care attendance (odds ratio [OR] 2.14, 95% Cl 1.44-3.18). S aureus carriage was affected by age (peak incidence at 10 years) and male sex (OR 1.46, 1.25-1.70). Serotyping showed 42% vaccine type pneumococci. We noted a negative correlation for co-colonisation of S aureus and vaccine-type pneumococci (OR 0.68, 0.48-0.94), but not for S aureus and non-vaccine serotypes. These findings suggest a natural competition between colonisation with vaccine-type pneumococci and S aureus, which might explain the Increase in S aureus-related otitis media after vaccination.
