The country's Ministry of Health confirmed that a seventh man died Monday in the village of Kubu Sembelang in northern Sumatra.
The agency said preliminary findings indicate three of the confirmed cases spent the night of April 29 in a small room together with the woman who was the initial case when she was symptomatic and coughing frequently.
"Although human-to-human transmission cannot be ruled out, the search for a possible alternative source of exposure is continuing," WHO said in a statement. "To date, the investigation has found no evidence of spread within the general community and no evidence that efficient human-to-human transmission has occurred."
The virus has killed more than 120 people worldwide since 2003, with the majority of the deaths in Southeast Asia.

'Deadly dozen' reports diseases worsened by climate change
Health experts from the Wildlife Conservation Society today released a report that lists 12 pathogens that could spread into new regions as a result of climate change, with potential impacts to both human and wildlife health and global economies. Called The Deadly Dozen: Wildlife Diseases in the Age of Climate Change, the new report provides examples of diseases that could spread as a result of changes in temperatures and precipitation levels. The best defense, according to the report's authors, is a good offense in the form of wildlife monitoring to detect how these diseases are moving so health professionals can learn and prepare to mitigate their impact.
Boston University partners in NSF challenge to create wireless network using visible light
Boston University's College of Engineering is a partner launching a major program, under a National Science Foundation grant, to develop the next generation of wireless communications technology based on visible light instead of radio waves. Researchers expect to piggyback data communications capabilities on low-power light emitting diodes, or LEDs, to create "Smart Lighting" that would be faster and more secure than current network technology.
When a light goes on during thought processes
(PhysOrg.com) -- Thought processes made visible: An international team of scientists headed by Mazahir Hasan of the Max Planck Institute for Medical Research in Heidelberg has succeeded in optically detecting individual action potentials in the brains of living animals. The scientists introduced fluorescent indicator proteins into the brain cells of mice via viral gene vectors: the illumination of the fluorescent proteins indicates both when and which neurons are communicating with each other.
New findings indicate HIV/AIDS pandemic began around 1900, earlier than previously thought
New research indicates that the most pervasive global strain of HIV began spreading among humans between 1884 and 1924, suggesting that growing urbanization in colonial Africa set the stage for the HIV/AIDS pandemic.
Animals farmed for meat are the No. 1 source of food poisoning bug, study shows
A study by researchers from Lancashire, England, and Chicago, IL, found that 97 percent of campylobacteriosis cases sampled in Lancashire were caused by bacteria typically found in chicken and livestock. The work, which appears September 26 in the open-access journal
PLoS Genetics, is based on DNA-sequence comparison of thousands of bacteria collected from human patients and animal carriers.
Panasonic Develops World's First 3D Full HD Plasma Theater System
Panasonic has developed the world's first 3D full HD Plasma Theater System, which enables the viewing of true-to-life 3D images by using a 103-inch plasma television and a Blu-ray Disc (BD) player, distributing full high-definition (HD) (1920 x 1080 pixels) images to left eye and right eye. Panasonic will present this system at CEATEC JAPAN 2008, which is due to be held at Makuhari Messe from September 30 to October 4, 2008.
Why some primates, but not humans, can live with immunodeficiency viruses and not progress to AIDS
Key differences in immune system signaling and the production of specific immune regulatory molecules may explain why some primates are able to live with an immunodeficiency virus infection without progressing to AIDS-like illness, unlike other primate species, including rhesus macaques and humans, that succumb to disease.
Gene therapy for chronic pain gets first test in people
This week, University of Michigan scientists will begin a phase 1 clinical trial for the treatment of cancer-related pain, using a novel gene transfer vector injected into the skin to deliver a pain-relieving gene to the nervous system.
