What are the first signs of COVID?

Overview

Early symptoms of COVID-19 can be erratic and often mimic those of a common cold or seasonal flu, complicating the ability of Australians to recognise the infection in its initial stages.

With the growing reliance on rapid antigen tests (RATs), telehealth consultations, and home monitoring, it is essential to recognise the initial signs of illness for timely care. This approach helps to minimise the risk of virus transmission to others.

First signs of COVID

Typical early symptoms include:

• Sore throat
• Runny or stuffy nose
• Dry cough
• Extreme tiredness or feeling “drained”
• Headache
• Mild fever
• Muscle aches
• Loss of taste or smell (less frequent with newer variants)
• Sneezing (more prevalent with recent strains)

Symptoms may start mild and can intensify over the next 24 to 48 hours.

Symptoms in different age groups

• Adults: sore throat, blocked nose, fatigue, cough
• Children: fever, stomach pain, vomiting, or diarrhea may appear first
• Older adults: fatigue, weakness, decreased appetite, confusion, and occasionally minimal or no fever

Covid vs cold vs flu

When to see a GP

Seek medical attention if you experience:

• A fever that does not improve
• Difficulty breathing or increasing shortness of breath
• Chest pain or pressure
• Severe sore throat or trouble swallowing
• A persistent cough lasting more than 3 weeks
• Symptoms are worsening instead of improving
• You are pregnant, elderly, or have chronic conditions
• Your RAT result is negative, but you feel very unwell

Diagnosis

Healthcare providers may use the following methods to confirm a COVID-19 infection:

• Rapid antigen tests
• PCR tests (more accurate and used for high-risk patients)
• Chest X-rays (if breathing symptoms are severe)
• Blood tests to assess infection and inflammation
• Monitoring of oxygen levels

Treatment options

If COVID-19 is confirmed, treatment typically focuses on symptom relief and preventing complications.

• Rest
• Stay hydrated
• Paracetamol or ibuprofen for fever or pain
• Antiviral medications (for eligible high-risk patients)
• Avoid smoking or vaping
• Keep track of symptoms and seek assistance if they worsen

At-home supportive care includes:

• Warm fluids
• Using a humidifier for throat and nasal symptoms
• Avoiding alcohol
• Isolating until symptoms improve

How Hola Health can help

Conclusion

Early COVID-19 symptoms can be subtle and often mistaken for a cold or flu. Being aware of the initial signs allows you to respond swiftly and reduce the risk of spreading the virus.

If symptoms worsen or you fall into a higher-risk category, seek prompt medical advice from a GP or via telehealth to ensure timely and appropriate care.

FAQs

Is COVID-19 still transmissible in the early stages?

Yes. The virus can be transmitted even before symptoms become apparent.

Can COVID-19 begin without a fever?

Yes. Many Australians report no fever in the first 24 to 48 hours.

Do RATs detect COVID-19 on the first day?

Sometimes, but false negatives are common early on. Retesting after 24 hours is recommended.

Is loss of smell still a prevalent symptom?

It is less common with newer variants but can still occur.

When should I seek medical assistance?

Seek medical help if breathing becomes difficult, symptoms worsen, or you are considered high-risk.
