A 66-year-old woman belonging to Nawabpeta area of Nellore town succumbed to the disease, after three weeks treatment in a corporate hospital at Chennai few days ago. (Private hospital means that the State never has to acknowledge this case - Ro)
However,
an agriculture labourer of Nellipudi village in Vakadu mandal, survived with treatment at the same hospital, although he too was tested positive for Hantavirus.
In-charge epidemiologist, Dr Veera Pratap,
has denied report of a vernacular daily about the death of a 50-year-old woman due to the virus, at Chinnapadug-upadu village near Nellore. Dr Pratap, who assisted Dr Ramesh and his team, during their visit to the district said that
the woman tested negative for Hantavirus. However, she was also treated at the same hospital in Chennai, where the other two cases were under treatment.
...
Meanwhile, the medical and health wing officials, have started collecting blood samples from the family members of the patients, and people living in the locality as a precautionary measure. The district medical and health officer, Dr N. Dasaradha-ramaiah, told this newspaper that they will send the samples for testing.

Again at the end of the month;
No Hanta tests, patients hit
October 31, 2011 DC Hyderabad .
Since the state does not have a single testing facility for hantavirus, blood samples of suspected hantivirus cases are being sent to the National Institute of Virology in Pune.
It takes four to five days to get the test results, which is way too long when a patient affected by the deadly virus can go from normal to critical within 10 to 24 hours.
...
Delay in confirmation affects treatment options in a big way.
Fifty-two-year-old Bhagavana Rao from Karimnagar district, who is currently undergoing treatment for hantavirus in a private hospital in the city, had suffered cardiac arrest while the doctors were attending to him.
“The patient could be revived when he suffered a cardiac arrest but his condition had deteriorated suddenly. In hantavirus patients, it takes very little time for the patient to go from normal to suffering a cardiac arrest or a kidney failure,” said Dr M.V. Rao, senior general physician at Yashoda Hospital, who treated the patient.
Also, with a number of suspected cases being reported from the State and as the awareness about the disease increases, more and more samples will be directed to the NIV, which will increase the time taken to complete the tests.

Type of H-virus not identified
November 1, 2011 By Syed Akbar DC Hyderabad .
The Hantavirus cases reported from Karimnagar and Nellore districts will remain a “scientific mystery” as no virus culture or polymerase chain reaction tests were conducted on the blood samples obtained from patients.
Lab tests of blood samples from three patients in Nellore and one patient from Karimnagar were limited to just identifying the anti-Hantavirus IgM. No tests were conducted to identify the serotype or strain of the Hantavirus.
...
Dr K. Ramesh, research fellow from the National Institute of Epidemio-logy, Chennai, said they did not send the samples for virus strain identification. “We diagnosed the disease through antibodies,” he added.
Thus the strain or serotype of Hantavirus that had infected these four persons will remain a mystery. Senior virologist Dr Yogesh K. Gurav from the National Institute of Virology, who visited Hyderabad and other places, could not collect the blood samples from the patient as it would not help in identification of the virus. The only way to identify the strain is to catch infected rodents from the areas where the patients live.
“We have been advised to collect blood samples from patients with fever reporting from Karimnagar. Analysis of these samples by NIV will help in identification of the strain of the virus,” said Dr MV Rao, senior physician in Yashoda Hospital.

Hantavirus case turns out to be leptospirosisNovember 3, 2011 By DC Correspondent Nellore
The suspected hantavirus case in Brahmanapalli of Podalakur mandal turned out to be leptospirosis during tests in Chennai.
The victim, Abhinash of the village was taken to Chennai for treatment for continuous fever about 10 days ago. Initially it was suspected to be hantavirus. The medical reports of Vijaya Hospital, Chennai where he was treated indicate that the ailment is because of leptospirosis. He was brought back to the village on Wednesday as he responded to treatment and is recovering.
The district medical and health officer, Dr P. Dasaradharami Reddy, said that the report related to Hantavirus was negative. He said that both Hantavirus and leptospirosis are spread by rodents, pointing to similar symptoms. He said that leptospirosis cases were reported in the district in the past too.
Reacting to a question about the death of a 66-year-old woman of Nellore because of hantavirus about a month ago, he said that she was treated in Chennai and they did not have any reports to confirm the case. (that same woman from the first report in this post)
...
The DMHO also denied reports in vernacular dailies about hantavirus reported at Nayudupalli village in Marripadu mandal in a 65-year-old man. He said that he had examined the patient and records related to the treatment he took at Hyderabad. The reports indicate that he was treated for malaria and he was proved negative for hantavirus, the DMHO said.

There seems to be some misidentification going on largely due to the lack of a testing facility. However a second factor is the State's choice to count cases from public hospitals only. Both of these factors add a certain fuzziness to any outbreak reports in India.
