Public Health Wales is asking parents in Barry to reinforce hand hygiene after a cluster of Hepatitis A cases; vaccination has been offered to those in close contact
The local health authority has alerted families in Barry after a small cluster of Hepatitis A infections was identified. Public Health Wales has written to parents and carers of children in primary schools to request increased vigilance, particularly around handwashing.
Health teams say the cases involve the same strain and have been found in three separate households, which suggests there may be some local transmission. As a result, authorities are coordinating a measured response to limit further spread while reassuring the community that those affected are receiving care.
Hepatitis A is described by clinicians as an acute liver infection caused by a virus. In the majority of cases it leads to a short-term illness from which people make a full recovery without lasting liver damage. Public Health Wales stresses, however, that children can sometimes carry and pass on the virus without showing clear signs themselves, so extra caution is needed in settings such as primary schools and where nappies are changed.
Clear information has been issued so families know what precautions to take.
What Public Health Wales and local teams are doing
Health officials report they are working closely with the local health board and council teams to investigate how the infection is spreading and to put control measures in place. A multidisciplinary team of experts has been assembled to map contacts and understand transmission routes. As a precautionary measure, vaccination has already been offered to people identified as being in close contact with those who tested positive. Public Health Wales confirms that everyone judged to need the vaccine has been contacted directly to arrange it.
Vaccination: who is offered it and when
The vaccine has been provided mainly to household members and others who meet the public health definition of close contacts. Officials emphasise that the offer is preventative rather than an indication of severe disease in the community. If parents or carers have not been approached but believe they meet the contact criteria, they should follow the guidance provided by the health authority rather than contacting their GP for routine requests. The exception is vaccination for travel: people who need a Hepatitis A vaccine for foreign travel should still contact their GP or travel clinic as usual.
Practical steps parents and carers should take
Susan Mably, consultant in health protection for Public Health Wales, thanked local residents for their cooperation while teams carried out their enquiries and urged families to reinforce simple hygiene routines. The single most effective preventive action is robust handwashing: washing hands thoroughly with soap and water after using the toilet, after changing nappies and before preparing or eating food. Parents and carers are asked to supervise and remind young children about these habits since they are the most effective way to reduce onward transmission.
Recognising symptoms and seeking help
While many infected children show few or no signs, people who become unwell may experience symptoms such as a fever, extreme tiredness, loss of appetite, feeling sick, vomiting or yellowing of the skin or eyes (jaundice). Those with these symptoms are advised to contact their GP or NHS 111 Wales for clinical advice and assessment. Public Health Wales notes that those who have been unwell so far are receiving appropriate care and are recovering well, and reminds the community that early reporting helps limit further spread.
Community message and next steps
In summary, local health teams ask families in Barry to prioritise hygiene measures, follow vaccination advice if offered and remain alert for the symptoms described. The health authority will continue to monitor the situation and update affected households directly. By reinforcing handwashing routines and responding promptly when asked to take a precautionary vaccine, parents and carers can play a key role in limiting transmission and protecting vulnerable people in the community.
