    Abstract

    Introduction:
    Since the first human cases of H5N1 avian influenza virus infection were
    detected in Indonesia in 2005, the Sulianti Saroso Infectious Diseases Hospital in Jakarta has managed 27 confirmed cases from September 2005 to December 2007.

    Materials and Methods:
    We reviewed the clinical and epidemiological data of these patients.

    Results:
    Clinical and radiological features were not specific. Most patients were young and had indirect contact with infected poultry. The majority of cases presented to the Infectious Diseases hospital late when the patients already had features of the systemic inflammatory response syndrome (SIRS). The mortality was high at 77%.

    Conclusion:
    There is clearly an urgent need for better field diagnostics and therapeutics for the management of this emerging pathogen.

    Direct contact history referred to a patient who had direct
    contact with sick or dead poultry. Indirect contact referred
    to a patient who had contact with contaminated environments
    including fertiliser or animal markets.

    influenza

    Contact History
    The largest number of cases (12 or 44.4%) had indirect
    contact with poultry ? predominantly by visiting markets or
    areas where outbreaks of poultry disease caused by H5N1
    AI had been reported (Fig. 3). Unfortunately, for a significant
    number of cases, the contact history could not be definitively
    obtained partly because the disease was often rapidly fatal
    by the time the patients presented to our hospital.

      Surprisingly, we found more patients with an indirect
      contact history than with a direct contact history. This is
      possibly because of transmission through fertilisers made
      from chicken manure. Japanese researchers have reported
      the detection of highly pathogenic H5N1 AI viruses in
      blowflies near infected poultry farms. (5*) The role of the
      contaminated environment in the transmission and
      propagation of H5N1 in humans and animals needs to be
      more clearly defined. It is also possible that some of the
      patients or their relatives might not have been forthcoming
      with their contact histories and this is borne out by the lack
      of contact data in about a third of the cases ? one of the
      limitations of this study.

        now we need that history for average, normal, non-sick, people

        or better : people with H3N2 or H1N1

          Re: _|Clinical and Epidemiological Features of Patients With Confirmed Avian Influenza|_

          Some interesting points from the article:
          There were a total of 27 laboratory confirmed cases of
          H5N1 AI in humans out of the 296 suspect cases managed
          at Sulianti Saroso Infectious Diseases Hospital in Jakarta
          between September 2005 and December 2007

          The largest number of cases (12 or 44.4&#37 had indirect
          contact with poultry – predominantly by visiting markets or
          areas where outbreaks of poultry disease caused by H5N1
          AI had been reported

          AI in humans is predominantly a disease of young adults
          and adolescents; the mean age among our patients was 16
          years with the oldest patient being 40 years old. This is
          probably due to a combination of factors including exposure
          to sick or dead poultry or contaminated markets where
          younger people are more likely to live and work.

          As a result of the delay in reaching definitive care, the
          majority of our patients were severely ill at presentation

              Reports examine high H5N1 death rate in Indonesia
              Robert Roos News Editor

              Jul 17, 2008 (CIDRAP News) ?

              Recent reports from Indonesian health officials tie the high fatality rate in human H5N1 influenza cases there to the difficulty of diagnosing the disease, late treatment with antiviral drugs, and a shortage of well-equipped hospitals.

              The case-fatality rate (CFR) in Indonesia, which leads the world in H5N1 cases, climbed from 63% in 2005 to 80% in 2006 and 85.7% in 2007, according to a report in the journal Annals Academy of Medicine Singapore.

              The CFR remains high so far this year, with 15 of 18 cases fatal, or 83.3%, according to World Health Organization (WHO) figures.

              By comparison, the CFR for the global total of 385 cases with 243 deaths is 63.1%.

              The fatality rate with Indonesian cases excluded is 53.2% (250 cases with 133 deaths, based on WHO figures).

              Two reports in the Singapore journal discuss H5N1 cases in Indonesia.

              One, written by Indonesian Ministry of Health (MOH) officials, looks at the 116 cases, including 94 fatal ones, the country recorded from 2005 through 2007 (the article also defends Indonesia's refusal to share H5N1 virus isolates with the WHO).

              A second article, written by hospital physicians, profiles the 27 cases, including 21 fatal ones, treated at Sulianti Saroso Infectious Diseases Hospital in Jakarta during that period.

              Hospital deficit called major factor
              According to the second report, Indonesia, like most developing countries, has few primary or secondary care hospitals with the protocols, isolation rooms, or cardio-respiratory support equipment to treat patients critically ill with H5N1 influenza.

              "This is probably the largest single contributor to the high mortality recorded," says the report, written by Sardikin Giriputro, MD, and colleagues.

              The MOH report cites the infection's nonspecific early clinical features, medical providers' unfamiliarity with the disease, and the late clinical stage of patients when hospitalized as potential causes of the high mortality.

              But with the increasing CFR over time, it adds, "the probability of an increase in the virulence of H5N1 viruses should also be considered."

              Without a fast, convenient test for H5N1 infection, the disease is difficult to diagnose, the hospital article says.

              Because the early signs and symptoms are not specific, primary care physicians "would find it extremely hard to predict which of their dozens of patients with influenza-like illness is going to turn out to have highly pathogenic H5N1 influenza in a few days time," it states.

              The MOH report says that 71% of H5N1 patients in Indonesia were treated with the antiviral drug oseltamivir (Tamiflu), but only two patients received it within the recommended time frame of 48 hours after the first symptoms.

              Those two patients survived.

              The survival rate decreased as the time to start treatment increased, the report says.

              Because early recognition is critical, the hospital report says, "The only conceivable solution is the development of cheap, effective point-of-care tests for H5N1 influenza that are as easy to use as a pregnancy test for example. These could be used by a rural primary healthcare clinic or district hospital in any developing country. This is clearly a challenge for the global scientific community."

              Most H5N1 patients were severely ill by the time they were brought to the hospital, the report says.

              "The vast majority had evidence of the systemic inflammatory response syndrome (SIRS) with marked tachycardia and tachypnoea" (rapid heart and breathing rates).

              Gender gap in fatality rate
              In other observations, the MOH report says the CFR was significantly higher among females than males?89% versus 73%; it offers no explanation for the difference.

              Adults had a higher CFR than children, 83% versus 76%, but the difference was not significant.

              The median age for all case-patients was 20 years.

              The MOH report also says that 24% of the 116 cases "occurred in 10 clusters of blood-related family members."

              But the report offers no opinion on how many cases of person-to-person transmission occurred. As reported previously, person-to-person transmission was considered likely in a widely publicized cluster of eight cases (seven confirmed, one probable) in Sumatra in May 2006.

              WHO reports on the Indonesian cases so far this year show only one family case cluster, involving a 38-year-old woman from West Jakarta, who fell ill in late January, and her 15-year-old daughter, who got sick in early February.

              According to the MOH authors, less than half of all the Indonesian patients?46%?had an "unmistakable history of direct contact with sick or dead poultry."

              Another 36% had been near sick or dead poultry without direct contact, and the possible sources for the other 18% were unclear, the report says.

              Among the Sulianti Saroso patients, 12 of 27 (44%) had indirect contact with poultry, mainly from visiting markets or areas where poultry outbreaks had occurred, the hospital report says.

              A smaller, unspecified number had direct contact with poultry, and the source was unclear for the rest.

              The authors speculate that some of the patients who had no direct contact with poultry might have caught the virus from fertilizers made of chicken manure.

              As for the epidemiologic curve, the MOH report says Indonesia averaged 5 cases per month from September 2005 through May 2007, but the rate dropped to 3 cases per month from June through December 2007.

              The WHO records indicate a similar pace so far this year, with 18 confirmed cases through June, but two thirds of those were in January and February.

              While 31 of 33 Indonesian provinces have had H5N1 outbreaks in birds, only 12 provinces have had human cases, the MOH report says.

                Contradictory.
                WHO stats have a total of 20 died; 3 Recovered.
                My list has 20 died, 3 Recovered. It does not count Tini Suhartini.

                WHO does not have Tini Suhartini, confirmed by Indo Lab (in my notes)
                Tini was from Asem Vill., Ranjeng, Cisitu, Sumedang. Died on 5/9. Twice to clinic in Siturja for diarrhea. On 5/13, all the Dr's, nurses and all the people who were in contact with her had blood drawn. A 5/18 article mentioned that 4 chickens tested positive in Pajagen Village.

                        Frequent Human H5N1 Transmission in Indonesia
                        Recombinomics Commentary 00:30
                        July 18, 2008

                        The MOH report also says that 24% of the 116 cases "occurred in 10 clusters of blood-related family members."

                        But the report offers no opinion on how many cases of person-to-person transmission occurred. As reported previously, person-to-person transmission was considered likely in a widely publicized cluster of eight cases (seven confirmed, one probable) in Sumatra in May 2006.

                        WHO reports on the Indonesian cases so far this year show only one family case cluster, involving a 38-year-old woman from West Jakarta, who fell ill in late January, and her 15-year-old daughter, who got sick in early February.

                        The above comments on the Indonesian Ministry of Health report include a gross underestimate of the number of cases in family clusters as well as the frequency of human to human (H2H) transmission in Indonesia.

                        The evidence for the underestimate can be seen in the confirmed clusters reported this year. Most of the recent confirmed cases in Indonesia have been in family clusters, but the index case was misdiagnosed with lung inflammation, typhus, or dengue fever. As a result, the index case was not tested, but the infection of the relative led to bird flu symptoms and testing, leading to confirmed H5N1 cases, but not to confirmed H5N1 clusters.

                        These three clear clusters had the appropriate time gap between the index case and the family member signaling H2H. This type of cluster was clear for the first confirmed case in Indonesia in 2005. The index case was infected from an unknown source. She then infected her sister who died without being tested. The father of the two girls was subsequently infected, and he tested positive (and the H5N1 isolated from him was used to make clade 2.1 vaccines, which led to Indonesia?s withholding of samples). Eventually, the index case was confirmed because of elevated H5N1 antibodies.

                        The second confirmed case in Indonesia was also in 2005 and also a cluster. In this case the index case infected her nephew. Both cases were confirmed, but the source of the index case infection was said to be fertilizer, but a match between putative H5N1 in the fertilizer and the index case was never demonstrated. The nephew was tested because he was a contact, but he never developed pneumonia and quickly recovered.

                        Both of these clusters clear were H2H, but as noted above, only the Karo cluster was officially acknowledged as H2H. Similar clusters were seen in Garut, but samples were not collected from index cases, who died before contacts were confirmed, and additional contacts who subsequently developed symptoms were treated with Tamiflu and were not confirmed.

                        Thus, it is likely that the number of H5N1 cluster members is close to half of the confirmed cases in Indonesia rather than the reported quarter.

                        The news blackout that followed the three recent clusters this year was not a coincidence.

                          There were 27 confirmed cases of AI managed at Sulianti
                          Saroso Infectious Diseases Hospital from September 2005
                          to December 2007. The positivity rate among suspect cases
                          is low (<10%). This may suggest the need to develop more
                          reliable criteria for suspect cases or to a certain extent
                          underdiagnosis, since some cases showed clinical features
                          highly suggestive of viral pneumonia were negative by
                          PCR. The timing of sampling at the later stage in the
                          clinical course of the disease will most likely decrease the
                          sensitivity of the test due to the lower viral load at that time.

                          what do they mean exactly?
                          underestimation ?

                            They mean that the treatment of the patient with tamiflu lowers the viral load, making it hard to detect the virus, leading to false negatives in the later tests.
                            Consequently, only 10% of suspect cases test positive.
