Strep A, or Group A Streptococcus (GAS), is a type of bacteria commonly found in the throat and on the skin. While it normally only leads to mild illnesses, it can sometimes cause severe and life-threatening infections. This article aims to provide a comprehensive overview of Strep A, covering everything from symptoms and transmission to treatment and prevention, to help you understand this infection and what it might mean for you.

What is Strep A?

Strep A is a bacterium that can cause a range of infections. These infections vary from minor illnesses like sore throats and skin infections to more serious diseases like pneumonia, sepsis, and necrotising fasciitis¹. Understanding Strep A is crucial for recognising and managing these infections effectively.

Symptoms and Signs of Strep A Infection

Strep A infections are often asymptomatic. However, where they do arise, recognising the symptoms of Strep A can help in early diagnosis and treatment. Common symptoms include:

• Sore throat
• Fever
• Nausea and vomiting
• Swollen lymph nodes
• Red and swollen tonsils, sometimes with white patches or streaks of pus (tonsilitis)
• Scabs or sores (impetigo)
• Headache
• Skin rash – known as scarlet fever

In severe cases, symptoms may include:

• High fever
• Severe muscle aches
• Pain, redness, and swelling around a wound
• Rapid breathing
• Severe pain and swelling in the skin²

Identifying these symptoms early can prevent complications and spread of the infection.

Invasive Group A Streptococcal (iGAS) Infections

While many Strep A infections are mild, invasive Group A Streptococcal (iGAS) infections are much more severe. iGAS occurs when the bacteria penetrate deeper parts of the body where they are not usually found, such as the blood, muscles, or lungs, leading to serious conditions like:

• Necrotising fasciitis: Often referred to as ‘flesh-eating disease’, this severe infection destroys muscles, fat, and skin tissue².
• Toxic shock syndrome: This rare but critical condition leads to sudden drops in blood pressure and multi-organ failure¹.
• Sepsis: A life-threatening response to infection causing tissue damage, organ failure, and death¹.

iGAS infections require immediate medical attention and aggressive treatment, often including intravenous antibiotics and surgical intervention².

How Does Strep A Spread?

Many cases of Strep A infection are asymptomatic. However, asymptomatic carriers are still infective. Strep A bacteria are highly contagious and can spread through:

• Direct contact with an infected person
• Respiratory droplets from coughing or sneezing
• Contact with contaminated objects or surfaces¹

Certain groups are at higher risk, including:

• Children in school or daycare settings
• The elderly
• People with weakened immune systems
• Those with chronic illnesses¹

Maintaining good hygiene practices can significantly reduce the risk of transmission.

Recent Outbreaks and Statistics

Strep A infections can show seasonal patterns, with peaks during the winter months. Recent reports indicate a surge in Strep A infections globally, including the UK. The UK Health Security Agency (UKHSA) has reported an increase in cases and is monitoring the situation closely³.

Globally, the data shows varying trends, but an overall rise in infections has been noted. For instance, a study by Imperial College London revealed significant insights into the global surge of Strep A cases⁴.

Diagnosis and Testing

Diagnosing Strep A usually involves a physical examination and a throat swab. The swab is tested to see if Group A Streptococcus bacteria are present. In some cases, blood tests or other types of samples may be needed, especially if a severe infection is suspected¹. Early diagnosis is crucial for effective treatment and preventing complications.

Treatment Options

Most Strep A infections can be treated with antibiotics. It’s essential to complete the entire course of antibiotics even if symptoms improve to ensure the bacteria are fully eradicated². It’s also important to note, you shouldn’t take any antibiotics that have not been directly prescribed by your doctor.

In addition to antibiotics, supportive care can help alleviate symptoms:

• Pain relievers such as paracetamol or ibuprofen
• Plenty of fluids
• Rest
• Warm saltwater gargles for throat pain

For more severe infections, hospitalisation and more intensive treatments may be necessary².

Prevention and Control Measures

Preventing the spread of Strep A involves simple but effective hygiene practices:

• Regular hand washing with soap and water
• Avoiding close contact with infected individuals
• Covering mouth and nose when coughing or sneezing
• Disinfecting frequently touched surfaces¹

As of now, there is no vaccine for Strep A, but research is ongoing to develop one. Staying informed and following public health guidelines can help keep these infections at bay⁴.

Public Health Implications

Strep A infections pose a considerable burden on public health systems. Increased awareness, timely diagnosis, and appropriate treatment are vital in managing these infections. Public health agencies have issued guidelines to help control the spread and impact of Strep A⁵. The UK government has provided updates on the seasonal activity of Group A Streptococcal infections, emphasising the importance of surveillance and preventive measures⁵.
