Stages of a Pandemic
Interpandemic period
Phase 1: No new influenza virus subtypes have been detected in humans. An influenza virus subtype that has caused human infection may be present in animals. If present in animals, the risk of human infection or disease is considered to be low.
Phase 2: No new influenza virus subtypes have been detected in humans. However, a circulating animal influenza virus subtype poses a substantial risk of human disease.
Pandemic alert period
Phase 3: Human infection(s) with a new subtype, but no human-to-human spread, or at most rare instances of spread to a close contact.
Phase 4: Small cluster(s) with limited human-to-human transmission but spread is highly localized, suggesting that the virus is not well adapted to humans.
Phase 5: Larger cluster(s) but human-to-human spread still localized, suggesting that the virus is becoming increasingly better adapted to humans, but may not yet be fully transmissible (substantial pandemic risk).
Pandemic period
Phase 6: Pandemic: increased and sustained transmission in general population.
H5N1 Wild Bird Flu at Ragunan Zoo in Jakarta Indonesia?
The minister said that among the birds that had tested positive for bird flu were peacocks, mynahs, wild ducks, pigmy chickens, eagles and herons.
The H5N1 positive wild ducks raise the possibility that the outbreak at the Ragunan Zoo, south of Jakarta, may be linked to migratory birds. Migratory birds were involved in H5N1 transport and transmission in Qinghai and Xinjiang provinces in China as well as Russia, Kazakhstan, and Mongolia.
Two Zoo Workers Test Positive for H5N1 in Jakarta Indonesia
Four pygmy chickens will be culled, but there are no plans for a mass culling exercise.
Titis Sari Muntorini, a Ragunan Zoo spokeswoman, said: "The other 15 infected birds, because they are endangered species, will for now be treated and isolated inside the surplus cages in the southern part of the zoo."
Health workers have also taken blood samples from zoo staff for testing as a precautionary measure.
Asymptomatic H5N1 Positive Exotic Birds at Ragunan Zoo
The 19 were from a sample of 27 birds that were randomly tested earlier this month.
The above comment indcating that the 27 birds tested were randomly selected is cause for concern. This would indicate that the exotic birds were asymptomatically infected and the infections were widespread. In addition to the 19 that were H5N1 positive, 4 more were inconclusive, which is commonly found for low levels of infection. Thus, only 4 of the 27 tested were negative.
Ten Hospitalized H5N1 Patients in Jakarta?
"Yes, there are two more people, with one suspected case an employee of Jakarta's Ragunan Zoo while the other is a vendor at the zoo," Siti said.
The minister said that as of Tuesday, there had been six people admitted to Sulianti Saroso Hospital in North Jakarta. Two of them earlier tested positive for the virus. Blood samples from the other patients have been sent to a Hong Kong laboratory.
The number of conflicting media reports and confusing quotes from officials continue to grow as does the list of patients hospitalized with bird flu conditions. Earlier reports indicated two zoo employees had tested positive for H5N1, but did not mention symptoms. The comment above indicates two people affiliated with the zoo are hospitalized with symptoms. One is an employee and another a vendor. Other media reports indicate the vendor is a street vendor, which would seem to indicate that transmission at the zoo was casual. Another media report describes a zoo trader as a 50 year-old male with a cough and breathing difficulties. It is not clear if this is the street vendor or a third person associated with the zoo with symptoms.
Hospitalized H5N1 Zoo Workers Grow to Three
In Indonesia, a 28-year-old guide and a 39-year-old vendor at a popular zoo in the capital were hospitalized Tuesday with symptoms of bird flu, said I Nyoman Kandun, director general of Communicable Disease Control.
The above description of the two people affiliated with the Ragunan Zoo who tested positive for H5N1 raise concerns about transmission. Media reports also describe the hospitalization of a 50 year-old zoo trader with a cough and breathing difficulties. Other reports have indicated that the two described above also have bird flu symptoms.
Increasing Human to Human Transmision of H5N1 in Jakarta
About the government`s decision on Monday to declare the outbreaks a National Extraordinary Happening (KLB), the minister said it was intended to make the public throughout the country alert to the disease.
"Besides, previously there was only one danger point, namely Pak Iwan Siswara but now there are two more danger points, namely RD and MG," she said.
The above "danger points" refer to three individuals who appear to be transmitting H5N1 to other people. The efficient human-to-human transmission is the major area of concern with regard to a catestrophic flu pandemic. H5N1 appears to be getting more and more efficient at such transmissions.
This transmission results in infections via casual contact and is becoming clearer at the Ragunan Zoo where three zoo employees have symptoms as well as in Tangang where the three human-to-human clusters are clustering.
The initial danger point was Pak Iwan Siswara who was a government auditor who died from H5N1. He is cited because he is the only member of his family listed as an official H5N1 case, but the index case was his 8 year old daughter, Sabrina Nurul Aisyah who developed bird flu symptoms on June 24. She is not listed as a confirmed case because there were only two serum samples collected and they were collected just 3 days apart so although both samples were positive and the antibody level was higher in the second collection, the increase was not 4 fold, which is the WHO standard, although that rise is expected in samples collected with longer time intervals between collections. Sabrina's 1 year old sister, Thalita Azizah, developed bird flu symptoms on June 29, but she died on July 9, so again she was not confirmed because of the lack of samples. Sabrina's father did not develop symptoms until July 2 and samples were collected at the appropriate time and he was PCR positive for H5N1. All three died within 5 days of each other, between July 9 and July 14 at Siloam Gleneagles Hospital in Tangerang. The onset dates strongly suggested that Sabrina infected her 1 year old sister and then one of the sisters infected their father.
Casual Human Transmision of H5N1 in Jakarta Raises Phase 5 Flags
The reason for this, according to Minister of Health Siti Fadilah Supari, is that the number of victims is higher following the case of Iwan Iswara, an auditor at the Supreme Audit Agency (BPK), who died together with his two daughters a month ago.
"At that time, there was only one occurrence, that of Mr Iwan and his daughters. But now, there are two others, that of Rini Dina and Mutiara," said Supari during a meeting at her office in Jakarta on Monday (19/09).
Rina Dina died at Bintaro International Hospital on Saturday (10/09), while Mutiara is still being treated at Suliyanto Saroso hospital.
The above comments highlight the increase in human-to-human transmission, but the number of people developing symptoms is increasing steadily and most transmissions appear to be casual. These casual transmission are cause for major concern.
Sixth H5N1 Fatality in Jakarta Causes Concerns
"The symptoms were heavy pneumonia, the same as bird flu symptoms. Her family confirmed to us that she had contact with dead chickens," Sardikin told Reuters.
The girl had been treated in a different hospital for five days before being brought to the Sulianti Saroso Hospital.
9 Year Old Ragunan Zoo Visitor Hospitalized with H5N1
One of the 8 patients were expected terjangkit the virus of birds flu that was treated in the Infection Hospital (RSPI) Sulianti Saroso evidently had visited to the Ragunan Zoo.
This was revealed by Deputy Director RSPI Sulianti Saroso, Dr Sardikin Giriputro in RSPI Sulianti Saroso, Sunter, Jakarta, Wednesday (21/9/2005).
Three More H5N1 Cases Admitted In Jakarta
...
The third patient, JM, had visited the Ragunan Zoo, where most randomly tested birds were H5N1 positive. Three or four zoo workers also developed H5N1 symptoms and two are also at the hospital.
...
The sudden jump in H5N1 cases this week is cause for concern. The case fatality rate for H5N1 confirmed and suspect acute cases in Indonesia remains at 100%.
Another Child Hospitalized with H5N1 After Ragunan Zoo Visit
As noted in the above machine translation, 8 year-old Raka Datyo was transferred to Sulianti Saroso on Wednesday. Raka was the 4th admission with bird flu symptoms and the second child who had visited the Ragunan Zoo recently. In addition, 3 or 4 zoo workers have also showed signs of bird flu.
The zoo cluster has been growing almost hourly. The zoo was closed Monday after it was reported that only four of 27 randomly selected birds at the zoo were negative for H5N1. The birds were asymptomatic and it is unclear when they became infected, but the number of zoo visitors or workers with bird flu symptoms has grown steadily.
Hospitalization of Four Zoo Visitors Raises H5N1 Pandemic Fears
The above machine translation indicates four more people were admitted to Sulianti Saroso Hospital on September 22. Media reports also describe a 15 year-old male who was also admitted with bird flu symptoms on September 22.
The two children who had visited the zoo brings the number of children to four. In addition three zoo employees have symptoms and two, Abdul Muntalib, a food vendor, and Ari Seytonini, a tour guide, are also at Sulianti Saroso.
115 Symptomatic Zoo Visitors Seek H5N1 Treatment in Jakarta
The above machine translation indicates that 115 visitors of the Ragunan Zoo in Jakarta came to the Sulianti Saroso Infectious Disease Hospital for treatment, but because their symptoms were mild, they were not treated.
The hospital has already admitted two zoo workers and four young visitors. The two workers were a tour guide and a vendor, suggesting contact with the H5N1 infected birds was limited. Similarly the age range of the visitors, 1.5 to 10 years of age also suggests contact would be limited.
Nine H5N1 Admissions Today Including Four Ragunan Zoo Visitors
The above machine translation describes 3 more patients admitted to Sulianti Saroso this evening, including two more children who had visited the Ragunan Zoo on 9/15 and "last Sunday". This morning two other children were admitted and yesterday there were two more who had visited the zoo. Thus, there are now 6 zoo vistors admitted and 115 zoo visitors with symptoms, who were turned away because they were not yet sick enough.

Indonesian avian flu case confirmed, could be human-to-human transmission
The World Health Organization confirmed an additional human case of avian influenza in Indonesia on Thursday.
A spokesperson for the Geneva-based agency confirmed the patient, an eight-year-old boy, may have caught the virus from another person.
The boy, who is recovering in hospital, is the nephew of a woman who died of H5N1 avian flu in Jakarta on Sept. 16. He had contact with his aunt after she became ill. Onset of his symptoms occurred four days after she became sick.
"It's possible that there's a common source (of infection). But . . . given the timing, we can't rule out human-to-human transmission," Maria Cheng, a WHO spokesperson, said in an interview from Geneva.

Flu shots offered in hurricane shelters
To prevent a potentially catastrophic outbreak of influenza in crowded hurricane shelters, the state Office of Public Health is giving vaccines to occupants of about 80 shelters around Louisiana.
The shots aren't being offered to the general public at this time because they might not be effective when flu season peaks in January and February, said Dr. Frank Welch, the Office of Public Health's medical director for immunization programs.
"But in shelters, where people are living in very close quarters in a very close environment, if flu were to get in there, it would spread like wildfire," he said.
About 10,000 shots have been given since the eight-day program started Friday, he said.
In addition to flu shots, people are administering hepatitis A and tetanus shots to ward off infections when people return to their homes, frequently by wading through foul water, and try to clean up.
Even though it is unlikely that people could contract hepatitis A from contaminated water, the vaccine is "a protective measure we can offer,"
Welch said.
Childhood vaccines also are available to shelter residents, he said.
Working with the Office of Public Health have been teams from other organizations, Welch said, including the federal Centers for Disease Control and Prevention, the U.S. Public Health Service, Louisiana State University and the Mayo Clinic.
USA Not to Issue Travel Warning
TEMPO Interactive, Jakarta:The US government will not issue a travel warning despite the bird flu disease in Indonesia.
The US Ambassador for Indonesia, Lynn Pascoe, has said that any such warning will not be issued.
“Such a warning will not be issued because there is yet to be any proof of spreading of the virus from human to human,” Pascoe told reporters after the signing of an agreement to send provide earthquake handling experts in Jakarta on Thursday afternoon (22/09).
Pascoe said that up to now, the disease had only spread from animals to humans, and a team of experts from the USA was already in Indonesia.
Thats a good question I don't know how long the shelf life is I will ask. I told my doctor why I wanted it and there was no problem getting the perscription 75mg 5 days worth.

IF you can get your doctor to get you Tamiflu how long is the shelf life on it? I think a big question is if you can get your doctor to prescribe it or not at this point also. How many doctors will believe it is a big enough threat to listen to their patients who want to get this ahead.
I'm stocking up on stuff slowly too -- I figure I can use it even if it doesn't come about and I won't have to worry if it does. Plus right now the prices are lower than they will be after Rita hits and all prices of everything goes up again.

The above comments indicate the number of patients admitted with bird flu symptoms continues to rise. The two additional zoo visitors brings that total to eight children in addition to two Ragunan Zoo workers who have been admitted to Suliant Saroso. Although the hospital is a referral hospital, it has limited admissions because of shortage of rooms and ventilators. Earlier in the week 115 zoo visitors with symptoms were denied admissions because the symptoms were not severe enough. Recently a class of 30 who visited the zoo had several members develop high fevers, and they also have not been admitted.
The zoo was closed on Monday, so many of the visitors from the weekend are just now developing symptoms or going to local hospitals, so the 8 admitted to Suliant Saroso reprsent only a small fraction of those visitors with symptoms.
The class of thirty was standing by the birds, where are heavily infected with H5N1, although the birds are asymptomatic. The large number of zoo visitors with symptoms repreaents a dramatic change in transmission, since media reports suggest the visitors were at the zoo on several different days and there have been no indication that those with symptoms had direct contact with the birds.
More data is required to understand the full extent of these transmissions, but the efficiency for human infections appears to have increased significantly.

Good stuff loam. Thanks.
...So-called 'bird flu' infects a variety of animals including cats, so I assume that's why the zoo was a center of infection. But I'm not hearing much chatter confirming the range of species it can hit. Also - research last year showed clearly that anti-virals do NOT work against H5N1 - and new reports say H5N1 is now 'developing immunities' to anti-virals.
Do you think anyone is going to tell the truth anytime soon?
Twelve H5N1 Bird Flu Patients Linked To Ragunan Zoo
...the number of patients at the Sulianti Saroso hospital with ties to the Rangunan Zoo is now up to 12. Three are zoo workers, including one, Karwati, who is in critical condition. She and tour guide, Aniek Setyonni, have both tested positive for H5N1 antibody.
The hospital also is treating food vendor, Abdul Muntalib. Test result announced indicated only 4 of 27 zoo birds tested were negative. The positive samples were collected September 5 and 6, so workers and visitors had been exposed to infected birds for some time before the zoo closed on September 19.
Although many of the patients had visited the zoo that weekend, Bilqis Widiawati had visited the zoo on September 11 and had been hospitalized at RS Medika Griya Sunter. Thus, like most of the suspected bird flu case, hospitalization was not reveal until transfer to Sulianti Saroso, which for Bilqis was September 24.
Thus, the number of zoo visitors with symptoms may be significantly higher than the 12 patients admitted. Indeed 115 visitors were turned away earlier this week and a high school class of 30 had visited the zoo on September 18, and students soon developed high fevers. These patients have also not been admitted.
The visit over an extended time period indicates that the infections were not due to an unusual event. It seems that multiple visitors where infected on several days and there had been little evidence of close contact.
The transmission of H5N1 to zoo visitors over an extended time period indicates that H5N1 is now transmitting via casual contact, a strong signal that the pandemic has moved to phase 5.

Confirmed H5N1 Bird Flu Deaths In Jakarta Increase to Six
The most recent is Karwati a mother of two who has been described in media repots as being 27 or 30. One report indicates she has a connection with the Ragunan Zoo, but most reports link her exposure to 15 birds that died near her home, including one or more that was eaten.
The other case, Riska, died last week and was just confirmed to be H5N1 positive. She also had contact with dead birds, but also had a pet bird, which again focuses attention on pet birds. The first three H5N1 reported fatalities were in a family from Tangerang. The birdcage across the street from their residence was H5N1 positive.
...There is considerable concern over false negatives or misdiagnosis...
...misdiagnosis is common...

Dengue Fever Misdaignosis of Fatal H5N1Case Causes Concern
...The entire area is reporting unusually high number of cases of dengue fever. The Philippines has recorded 259 dengue fever deaths.
Last year the index case of human-to-human transmission in Thailand was diagnosed as dengue fever because she vomited blood and had a nose bleed. She fatally infected her mother, who was H5N1 positive. Her aunt was also H5N1 positive.
The confusion of pandemic influenza with dengue fever was also seen in the 1918 flu pandemic...led to mis-diagnosis of dengue fever, typhoid, and cholera.
The spread of H5N1 in Indonesia suggests monitoring efforts in the region are far from adequate. Indonesia now has 10 acknowledged H5N1 cases. Six have died and one has been discharged. Two are in South Sulaweto, indicating H5N1 in humans has spread far and wide....
