A surge in flu cases has been reported in the Illawarra region, with confirmed infections tripling over the past month. Public health officials have noted a sharp increase in cases, raising concerns about the spread of the virus. The local health authority had previously offered a free flu vaccine for children, but the supply has now been exhausted. This has left many families scrambling for alternative options, as the vaccine is no longer available at no cost. Health workers are urging parents to consider private vaccination services, though costs may be a barrier for some. The situation highlights the challenges of managing seasonal outbreaks in the region.
