The unwillingness to discuss chronic illness in these conversations is especially concerning when combined with the scepticism faced by long Covid patients, who have to advocate for themselves so that medical professionals, employers and loved ones understand the gravity of their illness. Many report beingdisbelieved; shockingly, the then prime minister Boris Johnson scrawled “bollocks… this is Gulf War Syndrome” next to an October 2020 memo discussing long Covid and its symptoms. Anyone posting about their experience online is likely to be accused of lying, or being lazy, or in the pocket of big pharma. “I certainly think being disbelieved is one of the biggest traumas for Covid patients,” says Sinclair. (This distrust will be familiar to patients with myalgic encephalomyelitis/chronic fatigue syndrome, or ME/CFS, who have had their symptoms ignored or dismissed for decades. There is definitely overlap between long Covid and ME/CFS, says Sinclair, but they need to be differentiated.)

All of this conspires to make long Covid patients feel invisible, voiceless and forgotten. On top of the chronic pain and unpredictable recovery they face, the effect can be devastating to individuals’ mental health. Worrying numbers of long Covid patients report depression, anxiety and insomnia; in a 2022 survey, 45% of the nearly 200 patients who responded said they had contemplated suicide. “It’s a really awful illness,” says Heightman. “It’s not uncommon for us to have an appointment with someone, and them to share that they feel suicidal. It’s a particularly difficult illness to cope with, especially in people who were previously well, and the shock of losing their health and the uncertainty about the future is intolerable.”

Even though we are seeing fewer headlines about long Covid, previously healthy people are still contracting it, with each successive infection increasing the risk. “We sometimes will see someone who’s had Covid one, two or three times without problems, and then on the fourth time, suddenly they’ve got long Covid, and that makes them ill for a long time,” says Heightman. More disturbing still are the risks associated withchronic inflammation for long Covid patients, even if they have outwardly recovered. “It’s likely to age you,” says Sinclair, “so it’s going toshorten your telomeres, and therefore increase your risk of early death. It’s also going to increase your risk of any inflammatory condition: cancer is a high risk; we may get heart disease, diabetes, dementia. There’s a huge knock-on in every body system from long Covid.”
