Is it strep throat? How can you tell if you have a strep throat?
In order to diagnose a strep throat, your doctor will conduct a rapid strep test or examine a sample taken on a throat swab in a lab for a culture.
Sometimes, your doctor is able to diagnose strep throat based on your signs and symptoms, such as white spots in the throat area, fever, swollen lymph nodes in the neck, rashes etc. He will observe your symptoms carefully in a physical exam.
He might see white dots or patches in the back of your throat. Your tonsils might be red and inflamed. There might be some signs of bacterial infection that the doctor will observe to differentiate them from a strep throat.
One of the common signs of a strep throat is strep throat rash.
Strep throat rash: How do strep throat rashes look like?
A strep throat is usually accompanied with rashes. In particular, if the strep throat remains untreated for a longer period, the bacteria may grow and cause complications that may involve strep throat rashes. Strep bacteria may spread and cause such as infections and other problems in these regions:
- Rheumatic fever
- Pneumonia or other forms of lung infection
- Toxic schock syndrome
- Kidney problems
- Inflammatory reactions such as scarlet fever
A strep throat rash may look like a red, sandpaper-like rash on the neck, underarm, or groin, a little after the signs and symptoms of strep infection starts. This could be a sign of scarlet fever. You should contact your doctor if you or a child shows any symptoms similar to a strep rash.
The release of a particular toxin in the body is responsible for the characteristic rash that is seen with scarlet fever. The rash usually begins on the chest, neck, and armpit regions and then spreads to other areas of the body.
The rash is often more clear and reddened in certain areas such as:
- skin creases
- inguinal area
- creases of the elbow
Sometimes, capillaries may be ruptured in these areas to cause the rash to appear as lines (called Pastia lines).
The rash appears as fine and rough-textured (such as of a sandpaper), and contains multiple red lesions.
How long do strep throat rash last?
The rash may last about three to seven days. Once the rashes are gone, the skin begins to peel which may take a few weeks. The duration of skin peeling depends on the severity of the rash.
Inflammatory reactions and strep throat rash
Strep throat infection may cause inflammatory illnesses, such as scarlet fever, kidney inflammation, and rheumatic fever.
Scarlet fever is characterized by rashes. Other signs and symptoms of strep throat are sore throat, fever, headaches, swollen lymph nodes.
When to see a doctor if I notice rashes or other signs of strep throat?
Contact your doctor when you or your child:
- Experiences sore throat accompanied with swollen lymph nodes, particularly of the sore throat lasts longer than 2 days
- Has fever higher than 101 F (38.3 C)
- Has problems swallowing
- Is already going through strep throat treatment, but symptoms do not improve even after taking medicines for 2 days
You are particularly susceptible to strep throat if:
Several factors can increase your risk of strep throat infection:
- you are young in age – strep throat most affects children
- seasons – although a strep throat can occur anytime, it is more common in late fall and early spring, when strep bacteria grows fast
To prevent the infection, you should keep your hands clean, cover your mouth as you cough or sneeze, avoid sharing drinking bottles and glasses and eating utensils.
