HEALTH officials have launched a probe at a day nursery after a Batley toddler died from TB.
Little George Evans died last month after contracting a rare form of tuberculosis.
The 17-month-old - who attended a day nursery at Dewsbury District Hospital - was admitted to the hospital after developing breathing difficulties.
He was later transferred to a specialist unit at Leeds General Infirmary but died on October 20.
Today tests were still being carried out by North Kirklees Primary Care Trust and the Health Protection Agency to identify where George had caught the disease - which was not found to be infectious.
A spokesman for North Kirklees PCT, said: "The usual routine contact tracing measures have been put in place to try and understand where the individual concerned caught the tuberculosis.
"Close contacts of the case, including contacts at the day nursery, have been tested and results have excluded them as a source of TB infection.
"There is no reason to suspect a risk to anyone else at the nursery at present.
"Tests taken as a precautionary measure have shown no one else has picked up TB in the nursery.
"Parents have been kept informed, the day nursery concerned has worked closely with us and the investigation is going on."
A spokesman for the HPA in Yorkshire and the Humber, said the disease usually affected the lungs but in rare cases could affect other parts of the body, including the brain.
He said: "TB spreads from person to person only when it is coughed up from the lungs, and then inhaled directly by someone else.
"People who are not ill and do not have symptoms cannot spread the infection.
"TB is generally difficult to catch and most new cases of TB result from close contact with an infectious source."
