These include: tonsillitis sore throat scarlet fever impetigo erysipelas (a type of cellulitis) cellulitis pneumonia In rare cases, patients may go on to develop post-streptococcal complications, such as: rheumatic fever glomerulonephritis (heart and kidney diseases caused by an immune reaction to the bacteria)\u200b iGAS infections GAS can very rarely cause more serious conditions, known as invasive group A Streptococcus (iGAS) infections. These can include: bacteraemia (an infection of the bloodstream) septic arthritis meningitis necrotising fasciitis (a severe infection involving death of areas of soft tissue below the skin) Streptococcal toxic shock syndrome (rapidly progressive symptoms with low blood pressure and multi-organ failure) iGAS infections tend to happen in the elderly, the very young, or people with an underlying risk factor such as injecting drug use, alcoholism, immunosuppression or cancer. Treating GAS infections Most GAS infections are relatively mild illnesses that clear up on their own without the need for antibiotics. Often symptoms that look like GAS infections, like sore throats , are more commonly caused by viruses than GAS bacteria. If you or your child has a runny nose with their sore throat, its likely to be a virus infection. Sore throats caused by viruses do not need to be treated with antibiotics unless there are concerns about complications. More about sore throat symptoms, self-care at home, and what to do if your condition worsens Your healthcare professional will consider antibiotics if they think: you or your child need medication to get better or to ease symptoms you or your child are at risk of serious complications from a GAS infection you or your child has scarlet fever If you or your child is prescribed antibiotics, they could be in liquid or pill form. Its not uncommon for someone to have GAS bacteria on their skin or in their throat without being unwell. These people often dont know they have the bacteria and wont need antibiotics. Preventing GAS infection GAS are spread by close contact between individuals, through respiratory droplets (moisture in your breath) and direct skin contact. To help reduce the risk of picking up or spreading infections: Do wash your hands properly with soap for 20 seconds use a disposable tissue to catch coughs and sneezes and wash your hands afterwards keep away from others if you feel unwell Dont do not share contaminated food, utensils, cups and glasses, baths, bed linen or towels GAS can be a secondary infection, developing in people who are already unwell with illnesses like the flu. You can help protect your child from this risk by making sure they get their free flu vaccine this winter. New evidence also shows that the nasal spray flu vaccine offered to children may also protect them from GAS infection.
