A cough that lingers: when to see a GP in Fourways
A cough that interrupts sleep, returns repeatedly or does not seem to be improving deserves attention. Several conditions can cause similar symptoms, so the sound of a cough alone cannot tell you what is wrong. For adults in Fourways and nearby Johannesburg suburbs, a GP consultation can help establish the next step.
When a cough needs emergency care
Seek emergency help for severe or sudden breathing difficulty, breathlessness while resting or trying to speak, blue lips, new confusion or reduced alertness. New or severe chest pain, especially with breathlessness, and coughing up a substantial amount of fresh blood also need emergency assessment. Do not wait for an online appointment response.
Even small amounts of blood in sputum need prompt medical advice. Mediwell is a primary healthcare facility; life-threatening symptoms should go to emergency services or a hospital emergency unit. Source: NDoH Adult Primary Care 2026.
When to arrange a GP assessment
Contact a healthcare professional if your cough is persisting, repeatedly returning or worsening. Tell them if you also have fever, drenching night sweats, unexplained weight loss, unusual tiredness or chest discomfort. These symptoms can occur with tuberculosis (TB), but they can also have other causes. Assessment and appropriate testing are needed to distinguish them. Source: NICD: TB Frequently Asked Questions.
Do not wait for a cough to reach two weeks before asking about TB. South Africa’s Adult Primary Care 2026 guidance lists a current cough among the symptoms that should trigger assessment for TB, alongside fever, weight loss and drenching night sweats. The duration of symptoms is only part of the picture. Source: NDoH Adult Primary Care 2026.
Seek advice early if you live with HIV, receive treatment that suppresses your immune system or have another condition affecting your immunity. Mention any close contact with someone diagnosed with TB. People who have shared enclosed spaces with someone with infectious lung TB may need screening even if they feel well.

Why coughs can have different causes
Acute bronchitis is commonly caused by a virus. It can produce a dry cough initially and later yellow or green sputum. Sputum colour alone therefore cannot establish that you need an antibiotic. South African treatment guidance does not recommend antibiotics for uncomplicated acute bronchitis in people without underlying chronic obstructive pulmonary disease (COPD). A clinician needs to assess for pneumonia or other conditions that require different care. Source: NDoH: Primary Healthcare Chapter 17, Respiratory Conditions, 29 September 2026.
Asthma can cause cough, wheezing and shortness of breath, with symptoms that come and go. Allergic rhinitis can include a blocked or runny nose, throat irritation and coughing. These possibilities are reasons to describe the whole pattern, rather than assuming every persistent cough is an infection.

Sometimes a cough remains after a respiratory infection. That explanation should follow assessment, particularly if there is breathlessness, worsening illness or a risk of TB. Source: NDoH Adult Primary Care 2026.
What happens if TB testing is needed?
Your clinician may arrange a sputum test, which examines mucus coughed up from the lungs. South African guidance uses molecular testing to look for TB bacteria. Further tests or a chest X-ray may be needed depending on your symptoms, history and initial findings. Tell the clinician if you have previously had TB, because this can affect how results are interpreted. Source: NDoH: Primary Healthcare Chapter 23, Tuberculosis, 29 September 2026.
Ask how and when you will receive results, who will explain them and what to do if symptoms worsen while you wait. A negative initial test does not always end the investigation, particularly for people living with HIV who still have signs of TB. Attend the recommended review rather than assuming that no news means everything is clear. Source: NDoH: Primary Healthcare Chapter 23, Tuberculosis, 29 September 2026.
The NICD states that TB testing is free at public health facilities in South Africa. If using private care, ask about consultation and investigation costs and medical-aid arrangements beforehand. Source: NICD: TB Frequently Asked Questions.
How to prepare for your appointment
A short note on your phone can help you describe what has changed. Include:
- When the cough began and whether it is improving, worsening or recurring.
- Whether it is dry or brings up sputum, including any blood.
- Any fever, weight change, night sweats, wheezing or breathing difficulty.
- Whether sleep, exercise or ordinary daily activities are affected.
- Your medicines, inhalers and non-prescription products, plus relevant previous results.
- Smoking history, workplace dust or fumes, previous TB and possible TB contact.
You do not need to identify the diagnosis yourself. If you have already tried a remedy or received treatment, explain what you used and whether it helped. Ask which symptoms should prompt an earlier review and agree a follow-up plan.
Reducing the spread of respiratory infections
While arranging care, cover coughs with a tissue or your elbow, wash your hands regularly and stay home when you feel unwell, apart from obtaining necessary healthcare. These are practical measures recommended by the NICD for respiratory infections such as flu and RSV. Source: NICD: Respiratory illness public statement, 1 April 2026.
TB can spread through the air. Good ventilation and advice about masks and close contacts may be important when TB is suspected or diagnosed. Tell reception that you have a cough when arranging your visit and follow the facility’s instructions. These precautions support assessment; they should not become a reason to delay it.
