Causes of Scarlet Fever
Scarlet fever is an illness that occurs in people with strep throat.
The same bacteria that causes strep throat, causes scarlet fever.
Group A Streptococci or Streptococcus pyogenes bacteria live in mouth and nasal passages and are responsible for causing rashes and redness by the production of toxins.
Is Scarlet Fever Contagious?
Scarlet fever is definitely contagious.
If you happen to come in contact with droplets from an ill person through coughing, sneezing, saliva or even nasal secretion, you will catch the infection on touching your mouth, nose or eyes.,
Incubation period between the exposure and illness is about 2-4 days.
Touching a rash caused by the toxins released from the bacteria does not communicate the infection because bacterial toxin causes it and not the bacteria.
Sharing utensils with a person who is afflicted with the infection can result in spread of the illness.
Group A strep also contaminates food, so, sharing of food, especially milk, with a patient of scarlet fever can cause it as well.
Using towels, clothes or even bed linen with somebody who is infected is another way of spreading disease.
Cellulitis, a skin infection caused by group A strep, can spread the bacteria to other people through contact.
So, in nutshell, it is spread by-
– respiratory droplets in the air
– saliva or nasal secretion
– skin to skin contact
– sharing products
Risk Factors For Scarlet Fever
It is most common in children between 5 and 15 years of age. Being in close contact with others who are infected increases the risk of catching the infection.
Complications Associated With Scarlet Fever
Scarlet fever is associated with symptoms that disappear with the time after you begin the treatment but certain complications are caused by this infection.
Complications result due to the body’s immune response to the infection instead of bacteria.
If left untreated it can lead to damage in other organs of the body. Problems caused by it include-
- glomerulonephritis (kidney disease)
- ear, sinus and skin infection
- swollen lymph nodes in the neck
- abscess in the throat or tonsils
- rheumatic fever (can affect heart and nervous system)
- blood infection
Ear, sinus and skin infections as well as abscess can be treated using antibiotics.
Meningitis, osteomyelitis and toxic shock syndrome are some of the rare complications.
Diagnosing Scarlet Fever
A doctor generally diagnoses the scarlet fever by checking for the signs and symptoms related to it.
They will look for rashes on the skin and examine them.
Redness on the tongue and skin around certain areas is also examined. Doctor checks the health of the throat, tonsils and lymph nodes.
After diagnosing the symptoms, if the doctor suspects that the illness is scarlet fever a throat swab is collected to examine the cells by creating a culture.
Examination is done to check which bacteria caused the infection.
Rapid throat swab test is also done sometimes to get the report faster.
In some cases, the doctor asks for the blood test as well.
Treatment For Scarlet Fever
Certain medicines are recommended for the treatment of scarlet fever. It is primarily treated with antibiotics to kill the bacteria.
Consuming antibiotics also helps the immune system to defend the body against bacteria causing infection. They also help in reducing the symptoms or complications related to ear, nose and throat.
Antibiotics usually involve a 10 day course of penicillin or some other antibiotic if the patient is allergic to it.
24 hours after taking the antibiotics, the patient does not remain contagious but precautions should still be taken to avoid the spread.
To ease the pain and reduce the fever, over-the-counter medications are suggested such as-
- Ibuprofen (depending upon age)
Having foods like warm soup and gargling with salt water mix can help reduce the effects of sore throat.
Even consuming ice cream can help cure the pain and swelling. Soft foods and liquid diets can also help.
Aspirin should not be given to the patient when illness is associated with fever to prevent the risk of Reye’s syndrome.
It is a serious condition which causes confusion, swelling of the brain and problems in the liver.
Hydration is also very important for the patient, especially in cases of loss of appetite.
Calamine lotion can be used to treat itching.
There is currently no vaccine for scarlet fever but with the progress of the medical field, it might be created.
