In recent weeks, several cases of serious infections caused by the bacteria Streptococcus pyogenes, popularly known as “killer bacteria”, have been reported, including six deaths reported by the Chilean Ministry of Health, have been associated with its virus.
This situation has generated concern in the medical and general community. To address this worrying situation, we interviewed the general practitioner of the Clinical Hospital of the University of Antofagasta (HCUA) and academic of the Department of Medical Sciences of the Faculty of Medicine and Dentistry of the UA, Francisco Montenegro González, who offers us a detailed vision about the threat posed by this bacteria and the measures to combat it.
Impact of bacteria on adults and children
Dr. Montenegro explains that there are different types of Streptococcus bacteria, Streptococcus pyogenes being one of the most prominent in recent cases of post-influenza complications. This bacteria can cause respiratory infections such as bacterial pharyngitis, as well as skin infections such as erysipelas, impetigo and cellulitis. In more severe cases, it can cause necrotizing fasciitis, myositis, and toxic shock syndrome.
Infection treatment
The main treatment against Streptococcus pyogenes infections is antibiotics. It is crucial that anyone with symptoms see a doctor to receive proper evaluation and avoid self-medication, which can be harmful, the UA doctor added.
Bacterial aggressiveness
Streptococcus pyogenes is particularly aggressive due to its virulence factors, molecules that allow the microorganism to invade and damage the host. The bacteria can evade the immune system and release exotoxins, responsible for serious infections.
Climatic factors in Antofagasta
Although viral infections tend to increase in cold, humid climates, Dr. Montenegro clarifies that bacterial pharyngitis due to Streptococcus pyogenes may be more common in warm, humid climates. Crowding in closed spaces and poor ventilation also contribute to the spread.
recommendations
To reduce the risk of infection, Dr. Montenegro recommends:
- Frequent hand washing with soap and water.
- Avoid close contact with sick people.
- Use of a mask when respiratory symptoms occur.
- Cover your mouth and nose when coughing and sneezing.
- Maintain good personal hygiene.
- Consult early if you suspect a respiratory infection.
- Get vaccinated against influenza.
Warning signs
Symptoms that should prompt immediate medical consultation include:
- High fever (greater than 38 °C).
- Decay.
- Intense throat or skin pain.
- Headache.
- Skin lesions.
The community must be alert and take precautions to prevent the spread of this dangerous bacteria. Collaboration between the community and health professionals is essential to control this threat and protect public health.
