Long COVID is a poorly understood condition, with a wide spectrum of effects on multiple body systems and variable presentation in different individuals. Long COVID is of particular concern among older people (ie, aged 65 years or older), who are at greater risk than younger people of persisting symptoms associated with COVID-19. In addition, COVID-19 might trigger or exacerbate chronic conditions that occur commonly in older people, such as cardiovascular diseases, respiratory diseases, neurodegenerative conditions, and functional decline.
It is widely thought that lifespans are increasing globally. However, life expectancy has begun to stagnate in the UK, and is falling in more than 50 countries including the USA. Lifespan stagnation or decrease is a consequence of socioeconomic inequalities, lifestyle factors, and the COVID-19 pandemic. In the UK, the National Health Service spends vast sums treating chronic diseases; by some estimates, 40% of its costs go to treating preventable conditions.
The relationship of measures of age-related hearing loss such as pure-tone autiometry might not be as consistently associated with risk of dementia as previous studies have suggested. Peripheral age-related hearing loss has been posited as a midlife risk factor for dementia.
The October 21, 2022 cover story this week steps back from the news agenda to explore the impact of living with long Covid. For millions of people worldwide who have survived initial infection with the virus, recovery is slow. Symptoms such as breathlessness, fatigue and loss of smell or taste persist for months and, as our science editor Ian Sample explains, treatments that work for some may not be successful for others.
This week delegates to the Chinese Communist party’s 20th congress are in Beijing where they are expected to rubber stamp Xi Jinping’s historic third term as leader. Our big story looks at what the president’s supremacy means for the country and its closest neighbour – Taiwan – which lives in the shadow of Xi’s avowed intention to bring the island back under China’s tutelage.
Even mild COVID-19 is at least correlated with a startlingly wide spectrum of seemingly every illness. We need a much better taxonomy to address people’s suffering.
Long Covid – Whole Body Symptoms
From The Atlantic, October 5, 2022:
The cases of long covid that turn up in news reports, the medical literature, and in the offices of doctors like me fall into a few rough (and sometimes overlapping) categories. The first seems most readily explainable: the combination of organ damage, often profound physical debilitation, and poor mental health inflicted by severe pneumonia and resultant critical illness.
This serious long-term COVID-19 complication gets relatively little media attention despite its severity. The coronavirus can cause acute respiratory distress syndrome, the gravest form of pneumonia, which can in turn provoke a spiral of inflammation and injury that can end up taking down virtually every organ. I have seen many such complications in the ICU: failing hearts, collapsed lungs, failed kidneys, brain hemorrhages, limbs cut off from blood flow, and more. More than 7 million COVID-19 hospitalizations occurred in the United States before the Omicron wave, suggesting that millions could be left with damaged lungs or complications of critical illness. Whether these patients’ needs for care and rehabilitation are being adequately (and equitably) met is unclear: Ensuring that they are is an urgent priority.
Seasonal monsoon rainfall replenishes groundwater reserves in the Bengal basin of Bangladesh thanks to the region’s seemingly counterintuitive intensive dry-season irrigation practices, a new Science study finds.
Loss of smell is a well-known symptom of COVID-19. But parosmia, or an altered sense of smell, has forced some COVID-19 long-haulers to switch careers and sent them on a desperate quest for answers. @courtney_t_runn reports https://t.co/rFmmVtaMgY
