1. What is the cause of scarlet fever?

Scarlet fever is caused by the bacterium Streptococcus pyogenes, also known as Group A streptococcus (GAS). This bacterium is commonly found in the throat and nose of people with strep throat or skin infections caused by the bacteria.

2. How is scarlet fever spread?

Scarlet fever is spread through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouth or nose of people nearby, or they can be inhaled. The bacteria can also be spread through contact with contaminated surfaces, such as doorknobs, toys, or utensils.

3. What are the symptoms of scarlet fever?

The symptoms of scarlet fever typically appear 1 to 4 days after exposure to the bacteria. They include:

Sore throat: This is the most common symptom of scarlet fever. The throat may be red and swollen, and it may be painful to swallow.

Fever: A high fever of 102°F (38.9°C) or higher is common.

Rash: A red, fine-grained rash that starts on the chest and belly and then spreads to the rest of the body. The rash may feel like sandpaper to the touch.

Strawberry tongue: The tongue may be coated with a white coating that turns red and bumpy, giving it the appearance of a strawberry.

Swollen lymph nodes: The lymph nodes in the neck may be swollen and tender.

4. How is scarlet fever treated?

Scarlet fever is treated with antibiotics. Antibiotics are effective at killing the bacteria that cause the infection. It is important to start taking antibiotics as soon as possible, even if all of the symptoms are not present. Taking antibiotics for the full course of treatment, even if you feel better, is important to prevent the infection from returning.

5. What are the complications of scarlet fever?

Scarlet fever is usually a mild illness, but it can sometimes lead to serious complications. These complications can include:

Rheumatic fever: This is a serious inflammatory condition that can affect the heart, joints, brain, and other organs.

Post-streptococcal glomerulonephritis (PSGN): This is a serious kidney infection that can lead to kidney failure.

Scarlet fever pneumonia: This is an infection of the lungs that can be life-threatening.

Scarlet fever sinusitis: This is an infection of the sinuses that can be painful and difficult to treat.

6. How can scarlet fever be prevented?

The following measures can help to prevent scarlet fever:

Wash your hands often: This is the best way to prevent the spread of germs, including the bacteria that cause scarlet fever. Wash your hands with soap and water for at least 20 seconds, especially after coughing or sneezing, and before eating or preparing food.

Avoid close contact with sick people: Stay away from people who are sick with scarlet fever or strep throat. If you must be around someone who is sick, try to wear a mask and wash your hands often.

Cover your mouth and nose when you cough or sneeze: This will help to prevent the spread of germs from your respiratory droplets.

Don't share personal items: Do not share towels, utensils, or other personal items with someone who is sick with scarlet fever or strep throat.

Get vaccinated: There is a vaccine available to prevent scarlet fever. The vaccine is not as effective as preventing the infection, but it can help to reduce the severity of the illness.
