Because the COVID pandemic nears 1,000 days in Australia, we’re well-versed in recognizing the cough, fever and fatigue that characterize the infection.

Almost 50% of Australians have finally had COVID. Many of us will recover well, however, many will experience lingering or new symptoms for extended periods.

Once we ride out COVID’s peaks and troughs, a fresh wave of long COVID is emerging. But there’s still a whole lot we have no idea about any of it.

When does COVID become long COVID?

As a fresh illness, there is absolutely no one definition of when COVID ends and long COVID starts.

The Australian Department of Health defines long COVID as symptoms persisting or emerging at the very least a month after initial infection.

On the other hand, the Word Health Organization’s guidelines say long COVID starts 90 days after infection.

These wide-ranging timeframes have resulted in estimates that between 5 and 50% of individuals with COVID infections will establish long COVID.

Do you know the symptoms?

Definitions of long COVID are further complicated by way of a list of a lot more than 200 symptoms across ten areas of the body.

The most typical and longest-lasting symptoms include brain fog and impaired memory and concentration, fatigue, headaches, tinnitus (ringing in the ears), breathing difficulties, and lack of taste and smell.

For most people, these symptoms flare up after physical or mental exertion.

Rarer medical indications include chest pain and heart palpitations, visual impairment and diarrhea.

People suffering long COVID also have reported dental problems, with teeth becoming loose and crumbling, and gums bleeding.

What can cause long COVID?

We realize very little about how exactly long COVID affects your body, and why some individuals develop ongoing symptoms among others don’t.

A recently available study found COVID causes increases in chemical messengers that signal inflammation. As time passes, this damages the insulating myelin layer of nerve cells which are needed for nerves to transport and co-ordinate messages round the body and brain.

The disease fighting capability can also be acting in more obscure ways. Antibodies produced contrary to the SARS-CoV-2 virus could be targeting specialized cells in the walls of arteries in the mind, allowing inflammatory cells to enter brain tissue easier.

Although preliminary, these studies could hint at the underlying mechanisms of brain fog and issues with memory and concentration.

Other studies are so fresh from the study lab they’re yet to be peer-reviewed (so ought to be interpreted more cautiously).

One particular new study showed people who have long COVID have higher amounts of immune cells circulating in your body, and abnormally low degrees of the strain hormone cortisol.

Apart from stress, cortisol can be very important to regulating inflammation, so low cortisol levels could be a proven way the disease fighting capability becomes over-active. However, these email address details are definately not clear.

Another new study comparing individuals who recovered to those that developed long COVID found no significant changes in immune signaling chemicals in the blood, no differences in memory and thinking tests, no differences between groups in lung or heart function.

Together, these clinical tests claim that persistent activity of the might donate to long COVID in multiple and overlapping ways in the mind along with other organs.

The complexities and consequences of long COVID certainly are a key focus of research worldwide, and so are yet to be clearly defined. That is an important type of research because identifying what’s happening in your body may also help us identify targets to take care of long COVID.

Long COVID might have far-reaching impacts

We should also know how long COVID affects sufferers in more definable ways, such as for example their capability to work or study, and their standard of living.

The recently announced a parliamentary inquiry into long COVID, that may seek to answer these questions.

Between 5 and 15 % of these with COVID infections will continue to build up long COVID.

A federal parliamentary committee has been tasked with assessing medical, social, educational, and economic impacts of long-COVID.https://t.co/AAymOhqlv1

Although long COVID sufferers come in the minority, the cheapest estimate of a 5% rate of long COVID compatible around 500,000 Australians who now have, or will soon develop, long COVID.

If you are one of these, your GP ought to be your first port of demand assessment and ongoing management.

If needed, your GP can refer one to among the specialized long COVID clinics opening across Australia. These clinics try to treat the outward symptoms of long COVID using multidisciplinary approaches, and become a central hub for patients to gain access to evidence-based health care to combat long COVID.
