The document counts the records of calls for the so-called severe acute respiratory syndrome until June 23. Of these, about 60% of the cases were caused by H1N1, seasonally circulating virus, but were reported as being more likely to cause complications in people at greater risk, such as the elderly and children. For comparison, in the same period of 2017, there were 1,459 cases of influenza, with 237 deaths - an increase of 143%. At the time, the predominant virus was H3N2.

            Earlier this month, the country recorded 2,315 cases of influenza, with 274 deaths. Among the deaths this year, 74% were in patients with at least one risk factor for developing complications of the disease, such as the elderly (236 deaths), people with cardiovascular diseases (143 deaths) and diabetes (109 cases). The number of deaths of children under five has also increased. Only up to last week, there were 46 cases, three times that of the same period last year. Currently, the influenza mortality rate is 0.29% for every 100,000 inhabitants. Despite the increase, the total is still lower than in 2016, when there were 12,174 cases of influenza - the largest number since the 2009 pandemic.

                      Week 32

                      SUMMARY OF THE EPIDEMIOLOGICAL WEEK

                      ▪ Positivity for influenza and other respiratory viruses among the samples with
                      registered and sentinel units was 30.5% (3,463 / 11,341) for SG and
                      41.1% (777 / 1.890) for SRAG in ICU.
                      ▪ 27.7% (5,866 / 21,166) of the total samples with confirmed classification were confirmed for Influenza
                      of SARS cases reported in universal surveillance, with a predominance of Influenza virus
                      A (H1 N1) pdm09. Among notifications of SARS deaths, 31.1% (1,164 / 3,743) were
                      confirmed for influenza, with a predominance of Influenza A (H1N1) virus pdm09.
                      INFLUENZA SENTINATION SURVEILLANCE
                      The information on influenza sentinel surveillance presented in this report is based on the
                      data inserted in the SIVEP-Influenza by sentinel units distributed in all regions of the country. THE
                      Sentinel surveillance continues to be expanded and in the next bulletins will be incorporated, so
                      the data of the new sentinel units.
                      1 Flu Syndrome (SG): individual with fever, even if referred, accompanied by cough or sore throat and onset of symptoms in the last 07 days.
                      Severe Acute Respiratory Syndrome (SARS): an individual hospitalized with fever, even if reported, accompanied by a cough or sore throat and
                      dyspnoea. The following signs may also be observed: O2 saturation less than 95% or respiratory discomfort or
                      respiratory frequency.

                      Flu syndrome
                      By SE 32 of 2018 the SG sentry units collected 13,531 samples - it is recommended to
                      collection of 05 weekly samples per sentinel unit. Of these, 11,341 (83.8%) had results
                      and 30.5% (3,463 / 11,341) had a positive result for respiratory viruses, of which
                      2,074 (59.9%) were positive for influenza and 1,389 (40.1%) for other respiratory viruses (RSV,
                      Parainfluenza and Adenovirus). Among the influenza-positive samples, 909 (43.8%) were due to
                      of influenza A (H1N1) pdm09, 266 (12.8%) of influenza B, 113 (5.4%) of influenza A not subtyped and 786
                      (37.9%) of influenza A (H3N2). Among the other respiratory viruses, there was a predominance of 857
                      (61.7%) of RSV (Figure 1).
                      The South, Southeast regions present respectively the largest amounts of positive samples,
                      with emphasis on the greater circulation of Influenza A (H3N2), A (H1N1) pdm09 and RSV. The Northeast region
                      presents a greater circulation of Influenza A (H1N1) pdm09 and the Midwest and North regions of RSV
                      (Annex 1 - B).
                      As for the distribution of viruses by age group, individuals over 10 years old predominate
                      circulation of Influenza A (H1N1) pdm09 and A (H3N2) viruses. Among individuals under 10 years of age,
                      increased circulation of RSV and Influenza A (H1N1) pdm09.

                          1 Flu Syndrome (SG): individual with fever, even if referred, accompanied by cough or sore throat and onset of symptoms in the last 07 days.
                          Severe Acute Respiratory Syndrome (SARS): an individual hospitalized with fever, even if reported, accompanied by a cough or sore throat and
                          dyspnoea. The following signs may also be observed: O2 saturation less than 95% or respiratory discomfort or
                          respiratory frequency.

                          Flu syndrome
                          By SE 36 of 2018 SG sentries collected 15,207 samples - it is recommended that
                          collection of 05 weekly samples per sentinel unit. Of these, 12,876 (84.7%) had results
                          in the system and 29.2% (3,759 / 12,876) had positive results for respiratory viruses, of which
                          2,247 (59.8%) were positive for influenza and 1,512 (40.2%) for other respiratory viruses (RSV,
                          Parainfluenza and Adenovirus). Among the influenza-positive samples, 976 (43.4%) were due to
                          of influenza A (H1N1) pdm09, 318 (14.2%) of influenza B, 112 (5.0%) of influenza A not subtyped and 841
                          (37.4%) of influenza A (H3N2). Among the other respiratory viruses, there was a predominance of 933
                          (61.7%) of RSV (Figure 1).
                          The South, Southeast regions present respectively the largest amounts of positive samples,
                          with emphasis on the greater circulation of Influenza A (H3N2), A (H1N1) pdm09 and RSV. The Northeast region
                          presents a greater circulation of Influenza A (H1N1) pdm09 and the Midwest and North regions of RSV
                          (Annex 1 - B).
                          As for the distribution of viruses by age group, individuals over 10 years old predominate
                          circulation of Influenza A (H1N1) pdm09 and A (H3N2) viruses. Among individuals under 10 years of age,
                          increased circulation of RSV and Influenza A (H1N1) pdm09.

                          collections, with 2,213 (85.2%) presenting their results inserted into the system. Of these, 871 (39.4%)
                          were positive for respiratory viruses (Influenza, RSV, Parainfluenza and Adenovirus), of which
                          354 (40.6%) for influenza and 517 (59.4%) for other respiratory viruses (RSV, Parainfluenza and
                          Adenovirus). Of the influenza positive samples, 200 (56.5%) were detected for influenza
                          A (H1N1) pdm09, 20 (5.6%) for non-subtyped influenza A, 24 (6.8%) for influenza B and 110 (31.1%)
                          influenza A (H3N2). Among the other viruses, there is a predominance of 458 (88.2%) RSV (Figure 2).

                          Epidemiological Profile of Cases
                          Up to SE 36 of 2018 29,137 cases of SARS were reported, of which 23,629 (81.1%) were sample
                          processed and with results entered into the system. Of these, 26.6% (6,274 / 23,629) were classified as
                          as SARS by influenza and 22.0% (5,210 / 23,629) as other respiratory viruses. Among the cases of
                          influenza 3,727 (59.4%) were influenza A (H1N1) pdm09, 627 (10.0%) influenza A, not subtyped, 432
                          (6.9%) influenza B and 1,488 (23.7%) influenza A (H3N2), (Figure 3 and Annex 2).

                          The SARS cases of influenza had a median age of 37 years, varying from 0 to
                          107 years. In relation to the geographical distribution (Annexes 2 to 4), the Southeast region registered the largest
                          of cases of SARS by influenza 46.6% (2,912 / 6,274).
                          Epidemiological Profile of Deaths
                          Up to SE 36 of 2018 4,290 deaths were reported by SARS, which corresponds to 14.7%
                          (4,290 / 29,137) of the total cases. Of the total reported deaths, 1,277 (29.8%) were confirmed for
                          Influenza A virus, 852 (66.7%) due to influenza A (H1N1) pdm09, 128 (10.0%) influenza A
                          67 (5.2%) for influenza B and 230 (18.0%) influenza A (H3N2) (Figure 4 and Annex 2). The state
                          with the highest number of deaths due to influenza is S?o Paulo, with 42.3% (540 / 1,277), in relation to the country
                          (Annex 4).

                          of the onset of symptoms. Brazil, 2018 until the SE 36.
                          Among influenza deaths, the median age was 57 years, ranging from 0 to 107 years. The rate
                          of mortality from influenza in Brazil is at 0.61 / 100,000 inhabitants. Of the 1,277 individuals who were
                          964 (75.5%) had at least one risk factor for
                          adults ≥ 60 years, patients with heart disease, pneumopathies and diabetes mellitus. In addition, 997 (78.1%)
                          made use of antiviral, median of 4 days between the first symptoms and the beginning of the treatment,
                          ranging from 0 to 94 days (Table 1). It is recommended to start treatment preferentially in the first 48
                          hours.
