Effective disinfectants against impetigo can be used to kill the bacteria on surfaces and objects, reducing the risk of transmission.
What are the symptoms of impetigo and how is it diagnosed?
The symptoms of impetigo typically start with the appearance of red sores or blisters on the face, especially around the mouth and nose, although they can also appear on other parts of the body. The sores may burst and form a light brown crust, and the affected area may be itchy or painful. In some cases, the infection can spread to other parts of the body, such as the arms, legs, or trunk. A diagnosis of impetigo is usually made based on the appearance of the sores and the patient’s symptoms, although a bacterial culture or PCR test may be performed to confirm the diagnosis.
A healthcare professional will typically examine the sores and take a culture or swab to send to a laboratory for testing. The results of the test will help determine which type of bacteria is causing the infection and guide the treatment. It is essential to seek medical attention if symptoms persist or worsen over time, or if the infection is severe or widespread. Early diagnosis and treatment can help prevent the spread of impetigo and reduce the risk of complications, such as the infection spreading to other parts of the body or causing secondary infections.
What are the most effective disinfectants against impetigo?
The most effective disinfectants against impetigo are those that are specifically designed to kill Staphylococcus aureus and Streptococcus pyogenes bacteria.
