Germany Flu Season 2014-2015 Reports from the Robert Koch Institute

Week 14 (28.03. To 04.03.2015)
Summary evaluation of the epidemiological situation

The activity of acute respiratory illness (ARE) is nationwide in the 14th calendar week (CW) in 2015
compared to last week dropped significantly. The values ​​of the Praxisindex were a total in the field of
ARE-background activity and reached the normal level for the season.

The National Reference Center (NRC) for influenza were in the 14 KW 2015. 35 (71%) of 49
submitted Sentinel samples identified respiratory viruses. In 23 (47%) samples were Influenza viruses,
in four (8%), respiratory syncytial (RS) virus, human in three (6%) metapneumoviruses (hMPV)
and detected in six (12%) rhinoviruses.
After Infection Protection Act (IfSG) were used for the 14 week reporting (MW) in 2015 and so far 1,388 since
With 40 MW in 2014 were sent to 66,256 laboratory-confirmed clinical influenza cases to the RKI
(Data as of 04.08.2015).
Part of acute respiratory illness caused by influenza viruses yet.

Acute respiratory diseases (ARE)
The activity of acute respiratory illness (ARE) is nationwide in the 14th KW 2015 compared to
Previous week declined significantly. The values ​​of the index were practice in the twelve AGI regions in the field of
ARE-background activity (Table 1; Fig. 1.).

Reporting data for the Infection Protection Act (IfSG)
Previously were 1,388 laboratory-confirmed clinical influenza cases to the RKI for 14 MW in 2015
Submitted: 358 cases with non subtypisierter influenza A, 34 cases of influenza A (H1N1) pdm09, twelve
Cases of influenza A (H3N2), 34 cases of undifferentiated by influenza A or B and 950 cases with
Influenza B (Tab. 4). In 234 (17%) patients reported that they were hospitalized.
Since 2014, a total of 40 MW 66,256 laboratory-confirmed clinical influenza cases in
RKI transmitted. At 10,421 (16%) cases had indicated that they were hospitalized (data
08.04.2015).

So far, 202 deaths were transmitted with influenza infection at the RKI, including 129 cases with
not subtypisierter influenza A, 28 cases of influenza A (H1N1) pdm09, seven cases of influenza
A (H3N2), 17 cases with no differentiation by influenza A or B, and 16 cases with influenza B. Moreover,
were sent to five clinical-epidemiological confirmed deaths associated with
Influenza outbreaks in nursing homes are.

The different distribution of the identified influenza A subtypes in the AGI-Sentinel and the
Reporting data can be, among other things due to the fact that after the 2009 pandemic, the PCR for subtyping
for influenza A (H1N1) is established pdm09 much wider than for A (H3N2), or integrated in multiplex PCR
has become. The distribution of the circulating in the population influenza types and subtypes is in AGISentinel
therefore better represented.

Week 15 (04.04. To 10.04.2015)
Summary evaluation of the epidemiological situation

With influenza-weekly report for the 15th KW winter season ends. The incoming data
From week 16 continued to be assessed weekly and, exceptionally, for the 16 KW another weekly report
published. Subsequently, the reporting in the summer season is monthly.

The activity of acute respiratory illness (ARE) is the nation's 15th calendar week (CW) in 2015
compared to last week remained stable. The values ​​of the index were a total of practice in the field of
ARE-background activity and were in a normal for the season level.
The National Reference Center (NRC) for influenza were in the 15 KW 2015. 21 (53%) of 40
submitted Sentinel samples identified respiratory viruses. In 14 (35%) samples influenza viruses were
demonstrated.
After Infection Protection Act (IfSG) were used for the 15 week reporting (MW) in 2015 so far and since 756
With 40 MW in 2014 were sent to 67,471 laboratory-confirmed clinical influenza cases to the RKI
(Data as of 04.14.2015).
The end of the flu season has not been reached on the definition of AGI, part of the acute respiratory diseases
is not caused by influenza viruses.

Acute respiratory diseases (ARE)
The activity of acute respiratory illness (ARE) is the nation's 15th-KW 2015 compared to
Previous week remained stable and was in the range of background activity. The changes in the values ​​of
Index practice in individual AGI regions compared to last week can probably also on a comparable
be attributed ?ndertes consultation behavior during the Easter period (Table 1; Fig. 1.).

Reporting data for the Infection Protection Act (IfSG)
So far been 756 laboratory-confirmed clinical influenza cases to the RKI for 15 MW in 2015
Submitted: 140 cases with non subtypisierter influenza A, 17 cases of influenza A (H1N1) pdm09, six
Cases of influenza A (H3N2), 26 cases of undifferentiated by influenza A or B and 567 cases with
Influenza B (Tab. 4). In 126 (17%) patients reported that they were hospitalized.
Since 2014, a total of 40 MW 67,471 laboratory-confirmed clinical influenza cases in
RKI transmitted. At 10,527 (16%) cases had indicated that they were hospitalized (data
14.04.2015).
So far, 227 deaths were transmitted with influenza infection at the RKI, including 148 cases with
not subtypisierter influenza A, 29 cases of influenza A (H1N1) pdm09, seven cases of influenza
A (H3N2), 19 cases without differentiation by influenza A or B, and 19 cases with influenza B. Moreover,
were sent to five clinical-epidemiological confirmed deaths associated with
Influenza outbreaks in nursing homes are.
