“…Clinical and radiological manifestations in the infection by the influenza virus are not specific. ( 8 , 15 , 18 , 23 , 29 ) As mentioned before, the clinical picture is similar to that of the other respiratory infections, and can be aggravated by characteristics of the infectious agent or by the condition of the host, which until then, were not associated with the viral load and severity of symptoms. The finding of interstitial infiltrate in X-ray testing may represent the clinical picture of various diseases, generally referring to inflammatory processes or a local exacerbated immune response.…”

Objective:To describe the clinical aspects of cases of influenza A(H1N1)pdm09 in Brazil.Methods:A descriptive study of cases reported in Sistema de Informação de Agravos de Notificação (SINAN), 2009-2010.Results:As the final classification, we obtained 53,797 (56.79%) reported cases confirmed as a new influenza virus subtype, and 40,926 (43.21%) cases discarded. Fever was the most common sign, recorded in 99.74% of the confirmed and 98.92% of the discarded cases. Among the confirmed cases, the presence of comorbidities was reported in 32.53%, and in 38.29% of the discarded cases. The case fatality rate was 4.04%; 3,267 pregnant women were confirmed positive for influenza A new viral subtype and 2,730 of them were cured. The case fatality rate of pregnant women was 6.88%.Conclusion:The findings suggested concern of the health system with pregnant women, and patients with comorbidities and quality of care may have favored a lower mortality. We recommend that, when caring for patients with severe respiratory symptoms, with comorbidities, or pregnant women, health professionals should consider the need for hospital care, as these factors make up a worse prognosis of infection by the pandemic influenza virus.

“…In reference to the presence of comorbidities, in the population of our study we found close proportions (32.53% of those confirmed, 38.29% of those discarded, 35.48% of the pregnant women confirmed, 39.01% of the pregnant women discarded, and 58.99% of deaths) with those of other studies. ( 9 , 14 , 16 , 18 , 22 , 24 , 29 )…”

“…This is supported by several publications in the "non-North American, non-European" group which involved institutions such as WHO and CDC. [28][29][30]34 Despite the equal proportion of outbreak reports in North America/Europe vs other continents, non-representative sampling may also have played a role given that "Other continents" group was mainly represented by Asian countries (69% of the 32 reports), suggesting a relative lack of publication from other continents.…”

BackgroundHigh‐quality reporting of outbreak characteristics is fundamental to understand the behaviour of various strains of influenza virus and the impact of outbreak management strategies. However, few studies have systematically evaluated the quality of outbreak reporting.ObjectivesTo conduct a systematic analysis and assessment for reporting quality of influenza outbreaks based on a modified version of the STROBE statement, and to examine characteristics associated with reporting quality.MethodsA literature search was conducted across 3 online databases (PubMed, Web of Science, MEDLINE) for reports of influenza outbreaks (pandemic H1N1, avian, seasonal). The quality of reports meeting our eligibility criteria was assessed using the Modified STROBE criteria and assigned a score of 30. Mean differences (MD) and 95% confidence intervals (CI) were reported for comparisons of study characteristics.ResultsSixty‐four outbreak reports were available for analyses. The average Modified STROBE score was 20/30. Peer‐reviewed articles were associated with a better quality of reporting (MD 2.79, 95% CI 0.79‐4.78). Likewise, reports from authors affiliated with public health agencies were associated with better quality than those from academic institutions (MD 1.65, 95% CI−0.27‐3.56).ConclusionsThe development of explicit reporting guidelines specifically geared towards reporting of outbreak investigations proved to be useful. Providing information on patient characteristics, investigation details in introduction and results, as well as addressing limitations that could have biased the findings, were frequently missing in the published reports.

“…Infectious diseases are the major cause of illness and death for any given population [2,3]. Human Immunodeficiency Virus infection and Acquired Immune Deficiency Syndrome (HIV/AIDS), Severe Acute Respiratory Syndrome (SARS), H1N1 influenza and Poliomyelitis are examples of an infectious disease [3,4]. While globally the incidence of the infectious disease varies greatly between countries, in the 21st century, the main incidences are hand-foot-mouth disease, Hepatitis B, and Tuberculosis [3].…”
