Infectious Disease Control: A Global Imperative

Infectious Disease Control

A deadly bacterial infection known as streptococcal toxic shock syndrome (STSS) is currently spreading in Japan, prompting concerns about its causes and strategies for prevention. STSS, caused by toxins released by Streptococcus pyogenes (Group A Streptococcus or GAS), has shown a significant uptick in cases this year, with Japan's health ministry reporting 977 cases since the beginning of 2024, exceeding last year's total of 941 cases.

STSS is classified as a rare yet severe bacterial infection that can rapidly escalate into a life-threatening emergency, as emphasized by the Centers for Disease Control and Prevention (CDC). Initial symptoms often include fever, chills, muscle aches, nausea, and vomiting, with additional symptoms such as pain and swelling in the limbs noted by Japan's health authorities. Within 24 to 48 hours, the infection can progress to severe complications such as low blood pressure, organ failure, increased heart rate, and rapid breathing. Despite treatment efforts, STSS carries a significant mortality risk, with up to 30% of cases resulting in death, according to the CDC.

Dr. Céline Gounder, a renowned infectious diseases expert, explains that GAS, in addition to causing STSS, commonly manifests as sore throat and skin infections. In more severe cases, GAS can lead to infections in the blood, lungs, and even necrotizing fasciitis (commonly known as "flesh-eating" infections), with mortality rates ranging from 30% to 60% for these critical infections.

The rise in severe GAS infections raises questions about contributing factors, though exact reasons remain unclear. However, preventive measures can mitigate risks. Dr. Gounder recommends vaccination against varicella zoster virus (which causes chickenpox) and influenza, as these infections increase susceptibility to severe GAS infections. Additionally, individuals in close contact with those suffering from severe GAS infections, especially if immunocompromised, pregnant, or with open wounds, should receive antibiotics as a preventive measure.

STSS can affect anyone, but certain factors elevate risk levels. These include advanced age, particularly adults over 65, as well as conditions like diabetes, alcohol use disorder, and injuries that break the skin. Other predisposing factors for severe GAS infections include trauma, surgery, burns, immunosuppression, and previous infections like chickenpox or influenza.

Since late 2022, numerous countries, including the United Kingdom, Ireland, France, the Netherlands, and Sweden, have observed escalating rates of GAS infections. Dr. Gounder stresses the importance of robust infectious disease surveillance and control globally, emphasizing the need for continuous monitoring and proactive measures to curb outbreaks and prevent further spread.

In conclusion, while STSS remains a rare condition, its severity demands vigilance and action. Understanding its causes, recognizing symptoms early, and implementing preventive strategies such as vaccinations and prompt antibiotic use are crucial steps in combating this potentially deadly infection. By prioritizing public health measures and international cooperation, we can strive to mitigate the impact of STSS and safeguard communities worldwide.
