What Is An Antibiotic
Antibiotics are medicines that fight infections caused by bacteria in humans and animals by either killing the bacteria or making it difficult for the bacteria to grow and multiply.
Bacteria are germs. They live in the environment and all over the inside and outside of our bodies. Most bacteria are harmless and even helpful to people, but some can cause infections, like strep throat.
Pneumonia Can Be Fatal
When you acquire pneumonia, it could affect only one lung, both lungs, or spread from one to the other. It causes the air sacs in your lungs, also called alveoli, to become inflamed. This is what makes it difficult to breathe. Doctors typically treat pneumonia with antibiotics, but it remains the leading cause of infectious disease death in children under age five across the world. As with the flu, pneumonia can also be deadly for elderly people.
Smokers and those with asthma have a greater likelihood of catching all different strains of the disease. However, bacterial infection is the most common cause among adults in the United States.
Is Pneumonia Contagious When On Antibiotics
We know that pneumonia is contagious, but is it still contagious when you are on antibiotics? Before we answer that question, lets first explore how long pneumonia is contagious for.
When beginning antibiotic treatment for pneumonia, patients may typically observe improvements in health within two to three days. If by chance you actually get worse during this time, your doctor will change your treatment but only after at least three days.
Antibiotics have a high cure rate for pneumonia and are chosen based on a few factors, including the age of a patient, symptoms, severity, and the necessity of hospitalization.

Is Strep Throat Contagious
Strep throat can be contagious for about 2-3 weeks in individuals who are not taking antibiotics. However, individuals who do take antibiotics for strep throat usually are no longer contagious about 24- 48 hours after initiating antibiotic therapy. The bacteria that cause strep throat can be transmitted person-to-person by direct contact, especially from mucus droplets from the mouth and indirect contact, such as kissing and sharing utensils or drinking cups.
Professor Hanan H Balkhy
A great question Vismita. So when patients are admitted to the hospital and they start having more complexity from their disease so they can have what is known as a super infection with a bacteria, or if they’re in the intensive care unit and they’re also susceptible to having an overlying bacterial infection on top of the viral infection caused by SARS-CoV-2. And the WHO did come out with recommendations on when to use antibiotics within the course of SARS-CoV-2 patients, and those are usually within the moderate to severe disease classification of this illness.
Hannan explained to us why we are concerned about scenarios where people may be taking antibiotics without a prescription or may not be completing the cause, or may be taking antibiotics that has been prescribed for someone else because they heard that this was effective for someone else with similar symptoms. Explain to us why this is a matter of concern for us.

Antibiotics By Mechanism Of Action
Different types of antibiotics work against bacteria in different ways. Below are some examples.
Antibiotics that destroy cell walls:
- Beta-lactam antibiotics
Antibiotics that prevent bacteria from reproducing:
Some antibiotics work best on certain types of bacteria. Mainly, these are classified as antibiotics that target gram-positive bacteria with a simple cell wall, and those that target the more complex gram-negative bacteria.
Your healthcare provider may treat you with a broad-spectrum antibiotic that works against both gram-positive and gram-negative bacteria, but some infections may require a culture test to identify the specific form of bacteria. By identifying the exact type of bacteria that’s causing your illness, your healthcare provider can prescribe you the form of antibiotic that’s most effect against that particular bacteria.
When Do You Begin To Be Contagious
For some infections, such as strep throat and whooping cough, youre considered to be contagious when you start to experience symptoms.
Other infections, such as chlamydia, can be asymptomatic, meaning they dont present symptoms. For this reason, you could transmit these infections to other people without knowing it.

When To See A Doctor
You should see a doctor if you develop a sudden, painful sore throat accompanied by a fever.
If you are having trouble opening your mouth normally, are unable to swallow fluids to stay hydrated, or are unable to speak these are signs of a potential emergency and you should go to the doctor right away.
If you suspect strep throat, or there are white or red spots at the back of the throat and it feels painful, you should seek medical care.
What Happens If You Do Get It
Whooping cough can be difficult to diagnose in its early stages due to its similarity to other respiratory infections like the common cold. As the disease progresses, your doctor may be able to diagnose it by discussing your symptoms and listening to the accompanying cough.
They may also perform additional tests to help with their diagnosis, including:
- a swab from the back of the nose to test for the presence of the B. pertussis bacteria
- blood tests to check for signs of infection or inflammation
- a chest X-ray to look for inflammation or fluid accumulation in your lungs, particularly if the doctor suspects pneumonia as a complication of whooping cough
The treatment for whooping cough is a course of antibiotics. Since infants are particularly prone to complications from whooping cough, they may need to be hospitalized for treatment.
While youre being treated for whooping cough, you should be sure to rest thoroughly and stay hydrated. You should also stay home until youre no longer contagious, which is after five full days of antibiotics.

Flu And Colds: Are You Still Contagious
The common cold
Youre contagious: from one day before your first symptom to eight days after itYou can catch the common cold from over 200 different viruses, which lurk in the air and on common surfaces. You can be contagious before telltale symptoms, such as sneezing, stuffy or runny nose, sore throat and coughing, even begin. That means stellar hygiene is key 24/7, not just when you feel under the weather. And remember that a cold must run its course there is no cure for this common respiratory infection.
Youre contagious: from one day before your first symptom to up to seven days after itBoth types of the flu hitch rides on sneeze and cough droplets. Youre most infectious during the first three days that youre sick with the flu, because thats when you experience the most nasal secretions, says Linda Meloy, M.D., a professor in the division of general pediatrics at Virginia Commonwealth University Childrens Medical Center in Richmond, Virginia. This period also usually corresponds to when your fever is highest. An antiviral medication may shorten the stretch that youre contagious, so see your doctor at the first sign of symptoms fever, headache, muscle pain, fatigue, runny nose or sore throat.
Talk With Your Doctor If You Develop Any Side Effects Or Allergic Reactions While Taking An Antibiotic
In children, reactions from antibiotics are the most common cause of medication-related emergency department visits.
Common side effects range from minor to very severe health problems and can include:
More serious side effects can include:
- C. diff infection, which causes diarrhea that can lead to severe colon damage and death
- Severe and life-threatening allergic reactions
- Antibiotic-resistant infections
If you need antibiotics, the benefits usually outweigh the risks of side effects and antibiotic resistance.

How To Prevent Spreading Strep Throat
You can prevent spreading strep throat by being properly treated with a course of antibiotics.
In most cases, you will not be contagious within 2 days of starting antibiotics, even if all your symptoms are not gone.
You can also avoid spreading it by practicing good hygiene, frequently washing your hands, not sharing utensils, and not getting up close to others.
Strep throat is primarily spread through droplets from coughing, sneezing, or saliva, but can be spread from contaminated surfaces, too.
Practice frequent hand washing, avoid touching your face, and disinfect surfaces to reduce the transmission of strep throat.
Antibiotics Are Not A Cure
Antibiotics should only be used for specific bacterial infections. Taking antibiotics only when appropriate can help fight antimicrobial resistance. Antibiotics DO NOT work against viruses and cannot be used to treat infections like influenza or COVID-19.
You should also be sure to always take your full course of antibiotics. Don’t save them in case you get sick laterantibiotics you take for one infection may not work on another. You should also never share your antibiotics with anyone else or use antibiotics that were not prescribed to you.

What Is Strep Throat Caused By
Strep throat is a painful infection in the throat caused by streptococcal bacteria. This type of bacteria is extremely contagious and can be spread by coughing, sneezing, or sharing food and drinks. If your child touches a surface with the bacteria, like a doorknob, and then touches their mouth or nose, the bacteria may also spread this way. Often, a person may be carrying strep without exhibiting any symptoms.
How Is Strep Throat Treated
Strep throat is usually treated with antibiotics. Since it is a bacterial infection, it will not run its course like viral illnesses. Left untreated, streptococcal bacteria can cause inflammation of the kidneys, scarlet fever, rheumatic fever and a specific type of arthritis. Symptoms can be alleviated some with over-the-counter pain relievers, eating soft foods, gargling with warm, salty water several times a day, and getting lots of rest. In cases in which very young children have contracted strep throat, or if throat pain is so severe that eating and drinking are not possible, a visit to the hospital may be necessary so fluids can be given intravenously and your child can be monitored. Recurring strep throat may be treated with a tonsillectomy, which is a simple outpatient procedure to remove the tonsils and adenoids.

Whos Most Likely To Get It
Strep throat often spreads in late fall and early spring, when children are in school. People 5 to 15 years old are most likely to get strep. But adults can get it, too.
People who have a weakened immune system have a higher chance of coming down with strep. This includes anyone who:
- Was born with an immune system problem
Try not to share any personal items with someone who is sick. This includes:
- Cups and plates
- Food and drinks
Wash your hands and your children’s hands often. Or use an alcohol-based hand sanitizer. Always clean your hands before you eat and after you use the bathroom.
If you have strep, here are some things you or your child can do to avoid getting sick again:
- Take all the medicine your doctor prescribed, even if you start to feel better. Some bacteria may live and rebound if you stop the medication too soon.
- Once you’ve been on antibiotics for 2 to 3 days, throw out your old toothbrush and get a new one.
- Stay out of work or school for at least 24 hours after you start taking an antibiotic.
Circumstances That Require More Than 24 Hours
However, pertussis requires five days of antibiotics to make sure that it cannot be spread. Some intestinal infections and pneumonias can still be spread even after the child has finished the full course of antibiotics. Your local department of public health has printed guidelines that detail the recommendations for various types of infections.
The other factors to keep in mind when determining how soon a child should return to school are length of fever, energy level and appetite. Even if a child has completed the appropriate amount of antibiotic to stop him from being contagious, the child may still have fever, act fatigued or have a poor appetite. That would make him an unsuitable candidate for a full day of school. Staying at home for another day or two until he is up to full speed may be the best course of action.

Is Pneumonia Contagious After Taking Antibiotics
Even when a person is being treated for pneumonia with antibiotics and starts to feel better they can still be contagious for up to two weeks. In this case, patients should be cautious about people around them, cover their coughs and sneezes, and exercise proper hygiene at all times.
The rising prevalence of antibiotic resistance is to blame here. The antibiotic treatment may not always work because the bacteria can develop resistance to the medication. This is also hard to detect because the patient may start to slowly feeling better, so they assume the treatment works when really it should have worked more quickly.
Furthermore, in a healthy person whose body can very well fight off less serious bacteria, catching pneumonia from a person who is on antibiotics is way less likely, compared to the odds for someone with a weakened immune system. The defense system in these individuals is compromised, so although they would normally not get infected, they actually become quite ill.
What Dont Antibiotics Treat
Antibiotics DO NOT work on viruses, such as those that cause:
- Colds and runny noses, even if the mucus is thick, yellow, or green
- Most sore throats
- Most cases of chest colds
Antibiotics also ARE NOT needed for some common bacterial infections, including:
- Many sinus infections
- Some ear infections
This is because these illnesses will usually get better on their own, without antibiotics.
Taking antibiotics when theyre not needed wont help you, and their side effects can still cause harm.
Viruses are germs different from bacteria. They cause infections, such as colds and flu. However, antibiotics do not treat infections caused by viruses.

How Can I Feel Better
Placing cool or warm packs or washcloths over the infected eye can help. You can also take acetaminophen, if necessary. Clean the infected eye carefully with warm water and fresh, clean gauze or cotton balls.
Keep track of your symptoms, keep your hands clean, visit your doctor as needed, and follow your treatment instructions carefully. Within a week, your eyes should be feeling better.
Transmission Of Antibiotic Resistant Bacteria In Hospitals
The common ways in which bacteria can be passed from person to person include:
- contact with contaminated hands of hospital staff
- contact with contaminated surfaces such as door handles, over-bed tables and call bells
- contact with contaminated equipment, such as stethoscopes and blood pressure cuffs.

Symptoms Of Respiratory Infections Including Covid
Respiratory infections can spread easily between people. It is important to be aware of symptoms so you can take action to reduce the risk of spreading your infection to other people.
The symptoms of COVID-19 and other respiratory infections are very similar. It is not possible to tell if you have COVID-19, flu or another respiratory infection based on symptoms alone. Most people with COVID-19 and other respiratory infections will have a relatively mild illness, especially if they have been vaccinated.
If you have symptoms of a respiratory infection, such as COVID-19, and you have a high temperature or you do not feel well enough to go to work or carry out normal activities, you are advised to try to stay at home and avoid contact with other people.
Symptoms of COVID-19, flu and common respiratory infections include:
- continuous cough
- unexplained tiredness, lack of energy
- muscle aches or pains that are not due to exercise
- not wanting to eat or not feeling hungry
- headache that is unusual or longer lasting than usual
- sore throat, stuffy or runny nose
- diarrhoea, feeling sick or being sick
If you are feeling unwell with these symptoms you should get plenty of rest and drink water to keep hydrated. You can use medications such as paracetamol to help with your symptoms. Antibiotics are not recommended for viral respiratory infections because they will not relieve your symptoms or speed up your recovery.
You can find information about these symptoms on NHS.UK.
