I.2. Surveillance of acute respiratory infections
...
II.2.b. Summary
From data of the National Health Surveillance (monitoring modalities in clinical and laboratory) presents the current status of influenza-like illness (ILI), pneumonia, bronchiolitis in children under 2 years admitted respiratory diseases (SARI) and the case studies for the detection of respiratory viruses.
According to estimates from the Surveillance Clinic today TSI notifications would be in outbreak area about what happened in late 2012 and the last five years, excluding 2009. Pneumonia curve would be at the boundary between alert safety zone, like notifications curve bronchiolitis, comparing the current cases of the last 5 years. The estimated number of cases of SARI since EW 19 and until now show that the curve of notification would be in the boundary between alert and outbreak area in relation to the three previous years.
Regarding virological surveillance provided by the laboratories to SIVILA notifiers from the SE 1 to SE 27, 2013 were studied for respiratory viruses and reported 27293 cases of acute respiratory infection, with 7424 positive cases. During the period analyzed through EW 27 average positivity rate is 16.08%. In relation to the years 2010-2012, in 2013 there is a lower number of samples studied.
During 2013, through EW 27 in cumulative terms, of the 7424 samples positive for respiratory viruses found, 4233 were for Respiratory Syncytial Virus (61.21%), followed by all influenza viruses (21.96%) and Parainfluenza (9.76%).
In the first 27 weeks of 2013 have been identified 1975 cases of influenza virus circulated in every week of the year a total of 7424 reported respiratory virus, 55 corresponded to type B (2.90%) and 1920 type A, of the latter are identified as 249 cases and 1260 as H3 subtype H1N1 subtype pdm (12.19% and 56.85% respectively).
During the year 2013, 24 provinces reported cases studied for respiratory viruses, with the largest number of studied CABA, Buenos Aires, Santa Fe and Tucuman.
In all positive cases were found, with the largest number of jurisdictions with CABA cases (n = 2588) and Buenos Aires (n = 2129).
The 1975 positive cases of influenza epidemiological week 27 were distributed among the 24 provinces, with the largest number of cases in the courts of CABA, Buenos Aires, Santa Fe and Cordoba.
There was co-circulation of influenza A and B in 13 jurisdictions: CABA, Tierra del Fuego, Neuqu?n, Santa Fe, Chubut, Salta, Buenos Aires, Jujuy, Tucuman, Corrientes, Black River, Mendoza and San Juan. The remaining jurisdictions had type A influenza circulation The pdm H1N1 subtype distribution mainly include central region of the country.
Genomic characterizations obtained so far in the National Reference Laboratory, Respiratory Virus Diseases Service INEI-ANLIS "Carlos G. Malbr?n "indicate that the influenza A strains circulating strains are related to A/California/07/09 (H1N1) and A/Victoria/361/11 pdm09 (H3N2), on the other hand characterizations indicate type B strains Both lineages, Victoria and Yamagata, are predominant circulating latter. The strains mentioned components correspond to the counterparts vaccine vaccine formulation that is used during 2013.

II.2.b. Summary
From data of the National Health Surveillance (monitoring modalities in clinical and laboratory) presents the current status of influenza-like illness (ILI), pneumonia, bronchiolitis in children under 2 years admitted respiratory diseases (SARI) and the case studies for the detection of respiratory viruses.
According to estimates from the Surveillance Clinic today TSI notifications would be in outbreak area about what happened in late 2012 and the last five years, excluding 2009. However, they would be in decline after a peak in the SE 24. The curve of pneumonia would be in the safety zone boundary and alert while curve bronchiolitis notifications area should arise between safety and success, comparing current cases with those of the past five years. The estimated number of cases of SARI since EW 18 and to date shows that the present notification curve slopes upward to the SE 27 being in warning area in relation to the previous three years, after that week would have begun a decline the number of cases.
Regarding virological surveillance provided by the laboratories to SIVILA notifiers from the SE 1 to SE 29, 2013 were studied for respiratory viruses and reported 36272 cases of acute respiratory infection with 11509 positive cases. During the period analyzed through EW 29 average positivity rate is 20.35%. In relation to the years 2010-2012, in 2013 there is a lower number of samples studied. Of all of these, 33 656 patients are hospitalized for any reason, with 9941 finding positive results in 63.67% VSR. Meanwhile, from the SE 21-29 2556 analyzed samples of outpatients with 1683 bailouts, the 66.36% of which correspond to Influenza A.
During 2013, through EW 29 in cumulative terms, of the 11509 samples positive for respiratory viruses found, 6826 were for Respiratory Syncytial Virus (59.31%), followed by all influenza viruses (27.64%) and Parainfluenza (7.32%). In the first 29 weeks of 2013 have been identified 3182 cases of influenza virus circulated in every week of the year a total of 11509 reported respiratory virus, 85 corresponded to type B (2.67%) and 3097 type A, of the latter are identified as 399 cases and 1801 as H3 subtype H1N1 subtype pdm (12.64% and 56.60% respectively).
During the year 2013, 24 provinces reported cases studied for respiratory viruses, with the largest number of studied CABA, Buenos Aires, Santa Fe and Tucuman.
In all positive cases were found, with the largest number of jurisdictions with CABA cases (n = 3602) and Buenos Aires (n = 3595) - mainly observed RSV and Influenza-and Santa Fe (n = 736) with a predominance of influenza and RSV .
The 3182 positive cases of influenza epidemiological week 29 were distributed among the 24 provinces, with the largest number of cases in the courts of CABA, Buenos Aires, Santa Fe and Cordoba.
There was co-circulation of influenza A and B in 15 jurisdictions: Jujuy, Buenos Aires, Capital Federal. Santa Fe, Tucuman, Corrientes, Chubut, Salta, Mendoza, Neuquen, Rio Black, Tierra del Fuego, San Luis, Santiago del Estero, and San Juan. The remaining jurisdictions had type A influenza circulation The pdm H1N1 subtype distribution was mainly observed in the central region of the country.
Genomic characterizations obtained so far in the National Reference Laboratory, Respiratory Virus Diseases Service INEI-ANLIS "Carlos G. Malbr?n "indicate that the influenza A strains circulating strains are related to A/California/07/09 (H1N1) and A/Victoria/361/11 pdm09 (H3N2), on the other hand characterizations indicate type B strains Both lineages, Victoria and Yamagata, are predominant circulating latter.

II.1. Surveillance of acute respiratory infections
...
II.1.B. Summary
From data of the National Health Surveillance (on the modalities
clinical and laboratory monitoring) presents the current situation of the disease
Influenza type (ETI), pneumonia, bronchiolitis in children under 2 years, disease
respiratory interned (SARI) and the case studies for the detection of virus
breathing.
According to estimates from the Surveillance Clinic, currently the
TSI notifications would be in the boundary area and outbreak alert regarding
to what happened during the last five years, excluding 2009. Curve, according to the
estimate, would be in decline after a peak between weeks 24-26. The
pneumonia curve would be in the safety zone boundary and alert,
while curve bronchiolitis notifications should arise between zone
safety and success, comparing the current cases of the last 5 years. The
SARI case estimate since EW 23 and until now show that the
submit notification curve slopes upward to the SE 27
being in warning area in relation to the three previous years, from the SE
27, allegedly began a decline in the number of cases.
In relation to the virological provided by laboratories SIVILA
notifiers, from the SE 1 to SE 30, 2013 were studied for virus
39612 reported respiratory and acute respiratory infections, with 13326
positive cases. During the period under review to the SE 30 average positivity rate is 20.35%. In relation to the years 2010-2012, in 2013 there is only one
18% of samples analyzed to SE 30. Of all these, 36839
are for patients requiring hospitalization, with 11572 results
RSV positive finding at 62.79%. Meanwhile, since EW 21-30 were analyzed
2708 samples of patients receiving outpatient findings 1871
positive, 67% of which correspond to the influenza virus group, at the expense
the type A.
During 2013, through EW 30 in cumulative terms, of the positive samples 13326
for respiratory viruses found, 7784 were for Syncytial Virus
Respiratory (58.41%), followed by the set of Influenza virus (29.14%) and
Parainfluenza (6.81%).
In the first 30 weeks of 2013 have been identified 3883 cases of virus
Influenza distributed every week of the year a total of 13326 virus
reported respiratory, 101 corresponded to type B (2.60%) and 3782 type A, of
latter 477 cases were identified as subtype H3 and 2163 as subtype H1N1
pdm (12.28% and 55.70% respectively).
During the year 2013, 24 provinces reported cases studied for virus
breathing, with the largest number of studied CABA, Buenos
Aires, Santa Fe and Cordoba.
In all positive cases were found, with the largest number of jurisdictions
Buenos Aires cases (n = 3949) and CBA (n = 3879) - mainly observed VSR
and Influenza-and Santa Fe (n = 998) with a predominance of influenza and RSV.
The 3883 positive cases of influenza epidemiological week 30
distributed among the 24 provinces, with the largest number of cases in the
jurisdictions CABA, Buenos Aires, Córdoba and Santa Fe
There was co-circulation of influenza A and B in 15 jurisdictions: Jujuy, Buenos Aires,
Federal Capital. Santa Fe, Tucuman, Corrientes, Chubut, Salta, Mendoza, Neuquén, Río
Black, Tierra del Fuego, San Luis, Santiago del Estero, and San Juan. The remaining
jurisdictions had type A influenza circulation Subtype distribution
Pdm H1N1 was mainly observed in the central region of the country.
Regarding the distribution by age group, we see that 58% of cases
hospitalized correspond to less than 1 year, with a predominance of RSV, while
Influenza cases that mostly correspond to those over 15 years.
On the other hand, 68.4% of the samples studied in outpatients as
positive cases correspond to the group of 2-64 years (8629 cases of which
1036 were positive for Influenza). Within the latter, most are
between 25-64 years of age, the predominant influenza group,
H1N1 subtype primarily more than 50% of the positive samples.
Genomic characterizations obtained so far in the Laboratory
National Reference Service INEI Respiratory Virus-ANLIS "Carlos G.
Malbrán "indicate that the circulating influenza strains are related to
strain A/California/07/09 (H1N1) and A/Victoria/361/11 pdm09 (H3N2) on the other hand,
characterizations of type B strains indicate that both lineages, Victoria and Yamagata,
are predominantly circulating latter. -Mentioned strains
vaccine components correspond to the counterparts of the formula vaccinal
used during 2013.
