Third family member has 'Sars-like virus'
By James Gallagher Health and science reporter, BBC News
Scientists have sequenced the infection's full genome
A third member of a family in the UK hasbeen infected with a new respiratory illness similar to the deadly Sars virus, officials say.
It strengthens evidence that the virus can spread between people, however experts say the risk to thegeneral population remains small.
Of the 12 people confirmed to have the virus, five have died. This case appears to be a milder form of the infection and the patient is not being treated in hospital.The infection is thought to come from contact with animals. However, if the virus can spread between people it poses a much more serious threat.
This is the fourth case identified in the UK. Thefirst was a patient flown in from Qatar for treatment. The second was linked to travel to the Middle East and Pakistan. The virus is then thought to have spread from the second patient to his son andanother member of the family.
Low risk
Prof John Watson, head of the respiratory diseases department at the Health Protection Agency, said: "Although this patient had a mild form of respiratoryillness, as a precaution the HPA is advising that the patient self-isolate and limit contact with non-household members.
"Although this case appears to be due to person-to-person transmission, the risk ofinfection in contacts in most circumstances is still considered to be low." Other people who came into contact with the family are being tested.
The exact source of the new virus and how it spreadsis still unknown. The leading theory is that it comes from animals and the new Sars-like virus does also appear to be closely related to a virus in bats.
However, if the infection needs to jumpfrom an animal to a person with each infection, the threat would be much lower. The World Health Organization reported cases from within the same family in Saudi Arabia in November 2012. It was...
