A baby is recovering in Launceston General Hospital after contracting meningococcal, Tasmania's second case in several weeks.
The 10-month-old has the B strain, the state's health department said in a statement on Friday.
It comes after a man in his 60s from the Huon Valley contracted the W strain in late March.
Health authorities are urging those aged between six weeks and 20 years to get the state-funded meningococcal ACWY vaccine.
