Five years ago, COVID was all we could think about. Today, we’d rather forget about lockdowns, testing lines and social distancing. But the virus that sparked the pandemic, SARS-CoV-2, is still circulating.

Most people who get COVID today will experience only a mild illness. But some people are still at risk of severe illness and are more likely to be hospitalized with COVID. This includes older people, those who are immunocompromised by conditions such as cancer, and people with other health conditions such as diabetes.

Outcomes also tend to be more severe in those who experience social inequities such as homelessness. In the United Kingdom, people living in the 20% most deprived areas have a double chance of being hospitalized from infectious diseases than those in the least deprived areas.

How many cases and hospitalizations?

In Australia, 58,000 COVID cases have been reported so far in 2025. However, testing rates have declined and not all positive cases are reported to the government, so case numbers in the community are likely much higher.

The latest data from FluCan, a network of 14 hospitals, found 781 people were hospitalized for COVID complications in the first three months of the year. This “sentinel surveillance” data gives a snapshot from a handful of hospitals, so the actual number of hospitalizations across Australia is expected to be much higher.

While deaths are lower than previous years, 289 people died from COVID-related respiratory infections in the first two months of the year.

What can we expect as we head into winter?

We often see an increase in respiratory infections in winter.

However, COVID peaks aren’t just necessarily seasonal. Over the past few years, peaks have tended to appear around every six months.

What are the most common COVID symptoms?

Typical early symptoms of COVID included fever, cough, sore throat, runny nose and shortness of breath. These have remained the most common COVID symptoms across the multiple variant waves.

Early in the pandemic, we realized COVID caused a unique symptom called anosmia—the changed sense of taste or smell. Anosmia lasts about a week and in some cases can last longer. Anosmia was more frequently reported from infections due to the ancestral, Gamma, and Delta variants but not for the omicron variant, which emerged in 2021.

However, loss of smell still seems to be associated with some newer variants. A recent French study found anosmia was more frequently reported in people with JN.1.

But the researchers didn’t find any differences for other COVID symptoms between older and newer variants.

Should you bother doing a test?

Yes. Testing is particularly important if you experience COVID-like symptoms or were recently exposed to someone with COVID and are at high-risk of severe COVID. You might require timely treatment.

If you are at risk of severe COVID, you can see a doctor or visit a clinic with point-of-care testing services to access confirmatory PCR (polymerase chain reaction) testing.

Rapid antigen tests (RATs) approved by Australia’s regulator are also still available for personal use.

But a negative RAT doesn’t mean that you don’t have COVID—especially if you are symptomatic.

If you do test positive, while you don’t have to isolate, it’s best to stay at home.

If you do leave the house while experiencing COVID symptoms, minimize the spread to others by wearing a well-fitted mask, avoiding public places such as hospitals and avoiding contact with those at higher risk of severe COVID.

How long does COVID last these days?

In most people with mild to moderate COVID, it can last 7–10 days.

Symptomatic people can spread the infection to others from about 48 hours before you develop symptoms to about ten days after developing symptoms. Few people are infectious beyond that.

But symptoms can persist in more severe cases for longer.

A UK study which tracked the persistence of symptoms in 5,000 health-care workers found symptoms were less likely to last for more than 12 weeks in subsequent infections.

General fatigue, for example, was reported in 17.3% of people after the first infection compared with 12.8% after the second infection and 10.8% following the third infection.

Unvaccinated people also had more persistent symptoms.

Vaccinated people who catch COVID tend to present with milder disease and recover faster. This may be because vaccination prevents over-activation of the innate immune response.
