Strep throat is a common infection caused by bacteria known as Streptococcus pyogenes. The main impact is on the throat and tonsils, which can result in a painful and scratchy throat. People who have this strep infection may also have a high fever, headache, and sometimes feel nauseous or get a rash. This strep infection is different from other sore throats because it is caused by bacteria, not viruses. It can easily be spread from person to person through coughing, sneezing, or touching contaminated surfaces.
It’s important to know about strep throat because if it’s not treated, it could cause serious issues like rheumatic fever or kidney problems. These problems can cause long term health issues. Luckily, antibiotics can treat strep throat, which can lower the chance of problems and make a person get better faster. Understanding the signs and when to get medical help can help you better control the condition. Prompt and proper treatment of strep throat can stop it from spreading and help you get better faster.
7 Signs, Causes & Top Treatments
What is Strep Throat?
Strep throat is an infection caused by bacteria called Streptococcus pyogenes. This germ attacks the throat and tonsils, causing a painful, red throat that makes it difficult to swallow. People with strep throat usually have a high fever, headache, and swollen glands in the neck, as well as a sore throat. Others might feel sick, throw up, or get a red rash called scarlet fever.
Strep throat is not the same as other sore throats that are usually caused by viruses. Sore throats caused by viruses, such as the common cold or flu, typically have other symptoms like a runny nose or cough. They can also get better without needing antibiotics. On the other hand, strep throat needs to be treated with antibiotics to get rid of the bacteria and avoid problems. Another important difference is that strep throat usually comes on suddenly, while viral sore throats develop slowly.
It’s important to get the right diagnosis so that if you have strep throat, antibiotics can help you get better faster and prevent any serious health problems.
Causes of Strep Throat
Strep throat is a condition caused by a type of bacteria called Streptococcus pyogenes, also known as group A strep (GAS). These germs cause a sore throat, swollen tonsils, and fever by infecting the throat. When a person who is sick coughs or sneezes, the germs can be passed on to others easily through tiny drops in the air. The bacteria can also be spread by touching things like door handles or surfaces that have the bacteria on them. Strep throat is commonly found in busy places such as schools and daycares, where being close to others can cause the bacteria to spread more easily. Kids are at a higher risk of getting this strep infection.
Bacterial Infection
Strep throat is mostly caused by a bacteria called Streptococcus pyogenes, also known as group A strep. When these germs enter your throat and tonsils, they can make you sick. Your body fights an infection by causing pain, swelling, and other symptoms like a sore throat and fever. This happens because your immune system is trying to help. The bacteria cause the tissues in the throat to become swollen, which can make it hard to swallow or talk.
These germs can easily pass from one person to another and spread quickly in places where people are close together, like schools or crowded areas. If you think you have strep throat, it’s important to see a doctor because without the right treatment like antibiotics, the infection can get worse or spread to other parts of the body.
Transmission Through Respiratory Droplets
Strep throat is most contagious when an infected person coughs, sneezes, or talks, spreading tiny droplets in the air. These tiny drops have the bacteria that can give you strep throat. If you are close by and inhale the droplets, you could get infected. It can happen fast, especially in crowded places like schools, offices, or homes.
The germs in the droplets can also land on things like doorknobs, tables, or things that are shared. If you touch these surfaces and then touch your mouth, nose, or eyes, the bacteria can get inside you and give you strep throat. Due to its high level of contagiousness, strep throat can easily spread, specially among kids. It’s important to cover your mouth when you cough or sneeze and wash your hands a lot to stop spreading bacteria to other people.
Contact with Contaminated Surfaces
Strep throat can also be spread by touching surfaces with the bacteria on them, but this happens less often than getting it through the air. Bacteria can survive on things like doorknobs, tables, or objects If a person with strep throat touches these surfaces after coughing or sneezing, they can spread the bacteria.
When someone else touches the same surfaces and then touches their face, like their mouth, nose, or eyes, the bacteria can get into their body and make them sick. It is important to practice good hygiene, such as washing hands often and cleaning surfaces that are touched often, in order to stop the spread of strep throat. You are less likely to catch strep by touching infected surfaces, but it is still possible. To lower your risk, it is important to wash your hands and avoid touching your face.
Close Contact in Crowded Settings
Strep throat can spread more easily in places where people are close together, such as schools, daycares, or crowded homes. In these situations, it’s easy for bacteria to spread from person to person because they have direct contact. Kids are in danger because they often play and share things together, and they may not be as careful about washing their hands or covering their mouths when they cough or sneeze.
Because children’s immune systems are still growing, they can get sick more often than adults. Bacteria can spread fast in places where lots of people are together every day, like in classrooms or daycares. This is the reason why there are more cases of strep throat in these settings. It is important to follow good hygiene practices to prevent the spread of infection, such as washing hands regularly and keeping children home from school if they have symptoms.
Weakened Immune System
If someone’s immune system is not strong, they have a higher chance of catching strep throat when they are around the bacteria. Some medical conditions or treatments can weaken the immune system, making it more difficult for the body to fight off infections. As a result, it becomes easier for the strep bacteria to infect and make someone sick.
A person with a weak immune system is more likely to get sick and may take a longer time to get better from infections such as strep throat. This means they must be very careful to avoid coming into contact with the bacteria. Strep throat can easily spread in places where many people are close together, such as schools or daycares. It’s important for everyone, but especially those with weaker immune systems, to practice good hygiene and get help quickly if they start showing signs of strep throat.
Symptoms of Strep Throat
Strep throat has more specific and severe signs compared to viral sore throats, which can have a range of symptoms like coughing. Main signs:
- Severe sore throat: A sudden, severe throat pain is a common symptom of strep throat. Unlike viral infections, this pain usually doesn’t get better with home remedies like warm tea or lozenges, which makes it hard to talk or swallow.
- Pain when swallowing: Swallowing may hurt a lot because the throat is swollen. This pain can make it hard to eat or drink and is an important sign of strep throat.
- Red and swollen tonsils: The tonsils get red and puffy, and they might have white patches or streaks of pus. During a throat check, this noticeable sign of infection is frequently observed.
- Fever: A lot of people with strep throat usually have a high fever, usually more than 101°F (38.3°C). It often happens suddenly and comes with other symptoms such as feeling tired and having chills.
- Swollen lymph nodes: The lymph nodes in the neck might get bigger and hurt when you touch them. This happens because the body’s immune system reacts to the bacterial infection.
- Absence of cough: Unlike other viruses, strep throat usually does not result in a cough. Strep throat is often identified by the absence of a cough, which sets it apart from other colds or the flu.
- Headache and nausea: Strep throat can cause headaches, nausea, and vomiting, specially in children. These extra symptoms can make the sickness feel worse.
These signs usually show up 2 to 5 days after being infected with the bacteria.
Diagnosis
To know if someone has strep throat, a doctor usually begins by looking for common signs, such as enlarged tonsils, a sore throat, and fever.They will check the throat for redness or white patches, which are common signs of strep throat.
The best way to check for strep throat is with a rapid strep test. This test involves swabbing the back of the throat to look for the bacteria that can cause strep. The results usually come back fast, often within a few minutes. If the rapid test is not positive, but the doctor still believes it might be strep, they might do a throat culture. This means sending a sample from the throat to a laboratory to do more clinical tests. A throat culture takes longer, usually a few days, but it provides a more accurate result if the rapid test does not detect the infection.
Treatment of Strep Throat
Strep throat is usually treated with antibiotics like penicillin or amoxicillin. These drugs remove the bacteria that cause the infection and decrease symptoms like a sore throat and fever. It is crucial to finish all the antibiotics your doctor prescribed, even if you feel better in a few days. This helps to prevent the infection from returning and avoids causing more serious problems, such as rheumatic fever or kidney issues.
Many people start to feel better after 48 hours of taking the antibiotics. Even if the symptoms improve, you should still follow the doctor’s instructions and continue taking the medication. Quitting too early can let the germs remain inside your body, maybe causing more problems. You can also use non-prescription drugs to help relieve pain and reduce fever while the infection goes away, in addition to taking antibiotics.
In addition to taking antibiotics, patients can also control their symptoms with:
- Pain relievers: Ibuprofen or acetaminophen, which you can buy without a prescription, can reduce fever and relieve the pain from strep throat. They help control symptoms while the body fights the infection, making it easier to handle.
- Hydration: Drinking lots of liquids, specially warm teas or broths, can help calm a sore throat and keep you from getting dehydrated. It’s important to drink lots of water to help your body recover. Water keeps your throat moist and helps your body stay healthy.
- Rest: Having enough rest is important for getting better. Giving your body a chance to rest helps it fight off infections and makes the healing process faster, reducing how severe and how long you feel symptoms.
- Gargling with saltwater: wash your throat with warm saltwater can help reduce pain and swelling. It’s an easy way to clean your throat and feel better, so you can swallow and talk more comfortably.
Complications if Untreated
If you have strep throat, it can be fixed with antibiotics. If you don’t take care of it, it can lead to serious problems. The infection can move to nearby areas and cause problems like swollen tonsils or a sinus infection. These situations might lead to more pain and discomfort. If not treated, strep throat can sometimes cause serious problems like rheumatic fever that can harm the heart or kidney issues. It’s very important to go to a doctor and get the proper treatment if you think you have strep throat, even if your symptoms don’t seem too bad.
- Rheumatic fever: If you don’t treat strep throat, it can turn into a serious disease that causes inflammation. It impacts various areas of the body such as the heart, joints, skin, and brain. Rheumatic fever can lead to lasting harm, specially to the heart, and needs immediate medical care.
- Scarlet fever: A rash can sometimes happen with strep throat, specially in kids. The red rash seems like sandpaper and is usually accompanied by a high fever. Although scarlet fever can be treated with antibiotics, it can cause more serious problems if not treated.
- Post-streptococcal glomerulonephritis: This is a rare problem with the kidneys that can happen after someone gets a strep throat infection. It can make the kidneys swell and cause symptoms like blood in the urine and high blood pressure. It usually gets better by itself but may need medical observation.
Prevention
How to Prevent From Strep Throat
Prevent getting strep throat by staying away from people who have it. If someone you know has strep throat, make sure to stay away from them, specially their saliva or mucus. Good hygiene is important too. Make sure to wash your hands regularly, specially before you eat and after you cough or sneeze. Do not pass things like forks, spoons, or towels with others, because this can spread the bacteria. Teaching kids to cover their mouths when they cough and use tissues can help stop strep throat from spreading in schools and at home.
Key steps to prevent strep throat:
- Hand washing: Washing your hands often with soap and water can effectively reduce the risk of getting or spreading strep throat. It’s very important to wash your hands before eating, after coughing, sneezing, or using the bathroom to stop the germs from spreading.
- Avoid sharing personal items: Do not share things like forks, spoons, cups, or drinks with other people, specially in places like schools or daycares. Sharing these things can spread the bacteria that causes strep throat, making it more likely for people to get sick, specially in places where many people are together.
- Cover your mouth: Always cover your mouth and nose when coughing or sneezing to prevent the spread of droplets that can carry strep bacteria. Using a tissue or the inside of your elbow can help stop germs from reaching others.
If you have strep throat, make sure to stay home from work, school, or daycare until you have been on antibiotics for at least 24 hours. This stops the infection from spreading to other people. After taking antibiotics for a whole day, it’s less likely for you to spread the infection.
Frequently Asked Questions About Strep Throat
- Is it possible for Strep Throat to go away without treatment?
Strep throat may get better by itself, specially if it’s not too severe. Usually, antibiotics are advised to prevent possible complications such as rheumatic fever or kidney problems.
