Re: Colorado 2012-13 Season: Weeks 46-47

Week 47: influenza activity remained at a low level but increased compared to the previous week with most activity along the Front Range
**Change in Influenza Case County: Due to the increasing level of influenza activity in Colorado this season, as of November 25, 2012, all influenza-associated hospitalizations with any positive influenza test will be counted as cases. Until this point, only influenza-associated hospitalizations
with positive DFA, PCR, or viral culture tests were counted as cases.

Influenza B continued to be the predominate circulating strain.

? Six additional influenza-associated hospitalizations reported bringing the cumulative total to 26 hospitalizations from 6 counties, all in the Denver-Boulder metropolitan area and El Paso County.

? Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area increased to 1% for the first time since the 2012-2013 season began. Influenza-like illness reported by Mesa County remained near 0%.

? Sentinel hospital labs (16/19 reporting) tested 338 specimens and 43 (12.7%) were positive (compared to 6.3% the previous week). Of these, 39 (91%) were positive for influenza B.

? Of 31 specimens submitted to the state laboratory, 22 (71%) tested positive for influenza by PCR. Two specimens were collected during the previous week (week ending 11/17) and 20 specimens during the most recent week. Since October 7, 2012, among 54 specimens testing positive at the state laboratory, 14 (26%) have subtyped as H3, 2 (4%) as 2009 H1N1, and 38 (70%) as type B.

? No outbreaks were reported.

These numbers are significantly higher than what has been seen during the last 7 seasons by week 48, when an average of 8 influenza-associated hospitalizations were reported. This excludes the 2009-2010 H1N1
pandemic season when 2045 cases were identified by week 48.

• Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area continued to increase from 1.0% to 1.2%. Influenza-like illness reported by Mesa County remained near 0%.

• Sentinel hospital labs (19/19 reporting) tested 513 specimens and 49 (9.5%) were positive for influenza (compared to 11.6% the previous week). Of these, 42 (93%) were positive for influenza B.

• For the most recent week, 10 additional specimens (out of 11 submitted) tested positive for influenza by PCR at the state laboratory. Since the season began on October 7th, among 68 PCR positive specimens tested at the state laboratory, 19 (28%) have subtyped as H3, 2 (3%) as 2009 H1N1, and 47 (69%) as type B.

Re: Colorado 2012-13 Season: Weeks 46-51 (Two Pediatric Deaths Reported)

Week 51:
2 influenza-associated pediatric deaths reported (one each from Denver County and Jefferson County), occurring between mid-November and mid-December. Both children were infected with influenza B; were < age 3; and one had underlying health conditions.

There were 85 additional hospitalizations reported during the most recent week, bringing the cumulative total to 244 hospitalizations from 22 counties.

Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area continued to increase from 2.2&#37; to 3.0%. Influenza-like illness reported by Mesa County remained low but continued to increase from 0.2% to 0.5%.

For the most recent week, 27 additional specimens (out of 41 submitted) tested positive for influenza by PCR at the state laboratory. Since the season began on October 7th, among 157 PCR positive specimens tested at the state laboratory, 51 (38%) have subtyped as H3, 3 (2%) as 2009 H1N1, and 103 (76%) as type B.

Re: Colorado 2012-13 Season: Weeks 46-52 (No New Pediatric Deaths; Total Two)

Week 52: Widespread
The majority of the activity remains along the Front Range with indications of some influenza activity in other parts of the state.
• There were 127 additional hospitalizations reported during the most recent week, bringing the cumulative total to 373 hospitalizations from 25 counties. Due to reporting delays, it is expected that the number of influenza-associated hospitalizations for the week ending 12/29 will increase as cases diagnosed between 12/23 – 12/29 are subsequently reported.

• Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area increased slightly from 3.0&#37; to 3.1%. Influenza-like illness reported by Mesa County increased significantly from 0.5% to 2.0% with the majority of their activity split evenly between the 0-4 year and 5-24 year age groups.

• For the most recent week, 29 additional specimens (out of 38 submitted) tested positive for influenza by PCR at the state laboratory. Since the season began on October 7th, among 201 PCR positive specimens tested at the state laboratory, 79 (39%) have subtyped as H3, 6 (3%) as 2009 H1N1, and 116 (58%) as type B. Although influenza B continues to be the predominate circulating type, influenza A is increasing.

• No additional outbreaks have been confirmed.

• No additional pediatric deaths were confirmed.
