A 6-year-old female is diagnosed with a bacterial infection of the respiratory system

Respiratory tract infections (RTIs) are infections of parts of the body involved in breathing, such as the sinuses, throat, airways or lungs. Most RTIs get better without treatment, but sometimes you may need to see a GP.

Check if you have an RTI

Symptoms of an RTI include:

  • a cough – you may bring up mucus (phlegm)
  • sneezing
  • a stuffy or runny nose
  • a sore throat
  • headaches
  • muscle aches
  • breathlessness, tight chest or wheezing
  • a high temperature
  • feeling generally unwell

Things you can do yourself

Most RTIs pass within 1 to 2 weeks. You can usually treat your symptoms at home.

Do

  • get plenty of rest

  • drink lots of water to loosen any mucus and make it easier to cough up

  • drink a hot lemon and honey drink to help soothe a cough (not suitable for babies under 1 year old)

  • gargle with warm salty water if you have a sore throat (children should not try this)

  • raise your head up while sleeping using extra pillows to make breathing easier and clear your chest of mucus

  • use painkillers to bring down a fever and help ease a sore throat, headaches and muscle pain

  • try to stay at home and avoid contact with other people if you have a high temperature or you do not feel well enough to do your normal activities

Don’t

  • do not let children breathe in steam from a bowl of hot water as there's a risk of scalding

  • do not give aspirin to children under 16

  • do not smoke – it can make your symptoms worse

How to make a hot lemon and honey drink

  1. Squeeze half a lemon into a mug of boiled water
  2. Add 1 to 2 teaspoons of honey
  3. Drink while still warm

Do not give hot drinks to small children.

How to gargle with salt water

  1. Dissolve half a teaspoon of salt in a glass of warm water – warm water helps salt dissolve
  2. Gargle with the solution then spit it out – do not swallow it
  3. Repeat as often as you like

A pharmacist can help with an RTI

A pharmacist can suggest treatments to help relieve your symptoms, such as decongestants and nasal sprays.

You can also buy cough medicines and throat lozenges, although there's little evidence to show they help.

Some treatments contain paracetamol and ibuprofen.

If you're taking these medicines separately, be careful not to take more than the recommended dose.

Certain treatments are not suitable for children, babies and pregnant women. Your pharmacist can advise you about the best treatment for you or your child.

Information:

Call a pharmacy or contact them online before going in person. You can get medicines delivered or ask someone to collect them.

Non-urgent advice: See a GP if:

  • you feel very unwell or your symptoms get worse
  • you cough up blood or bloodstained mucus
  • you have had a cough for more than 3 weeks
  • you're pregnant
  • you're over 65
  • you have a weakened immune system – for example, because you have a condition like diabetes or you're having chemotherapy
  • you have a long-term health condition, such as a heart, lung or kidney condition

You may have pneumonia if your symptoms are severe.

Treatment from a GP

Treatment will depend on the cause of your RTI:

  • a virus (like colds) – this usually clears up by itself after a few weeks and antibiotics will not help
  • bacteria (like pneumonia) – a GP may prescribe antibiotics (make sure you complete the whole course as advised by a GP, even if you start to feel better)

Sometimes a sample of your mucus may need to be tested to see what's causing your RTI.

Use of antibiotics

Antibiotics are only used to treat bacterial infections. They're not used for treating viral infections because they do not work for this type of infection.

How to avoid passing RTIs on to others:

  • cover your mouth when you cough or sneeze
  • wash your hands regularly
  • throw away used tissues immediately

How to avoid getting an RTI

If you keep getting RTIs or you're at a high risk of getting one (for example, because you're over the age of 65 or have a serious long-term health condition), you should:

  • ask a GP about the annual flu vaccination – find out if you're eligible for the free flu vaccine
  • ask if you should have the pneumococcal vaccine – this helps prevent pneumonia
  • stop smoking if you smoke
  • drink less alcohol

Causes and types of RTIs

RTIs are often spread in the coughs and sneezes of someone with an infection.

There are several different types. They're usually grouped into upper and lower RTIs.

Flu can be an upper or lower RTI.

Lower RTIs tend to last longer and can be more serious.

What is the most common treatment for a bacterial infection?

Most bacterial infections can be effectively treated with antibiotics. They either kill bacteria or stop them multiplying. This helps the body's immune system to fight the bacteria. Your doctor's choice of antibiotic will depend on the bacteria that is causing the infection.

What can cause a bacterial infection?

You can get sick from getting harmful bacteria in your skin, gut (GI tract), lungs, heart, brain, blood or anywhere else in your body. Harmful bacteria from the environment, an infected person or animal, a bug bite or something contaminated (like food, water or surfaces) can cause infections.

Are bacterial infections contagious?

Many bacterial infections are contagious, meaning that they can be transmitted from person to person. There are many ways this can occur, including: close contact with a person who has a bacterial infection, including touching and kissing.

What common symptom should be assessed for in individuals with immunodeficiency?

Signs and symptoms of primary immunodeficiency can include: Frequent and recurrent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections. Inflammation and infection of internal organs. Blood disorders, such as low platelet count or anemia.
