Covid symptoms stay even after 6 months

For the study, the researchers included 1,733 Covid-19 patients who were discharged from Jin Yin-tan Hospital in Wuhan, China, between January 7 and May 29, 2020.

A new study found that three out of every four coronavirus patients treated at a Chinese hospital still experienced COVID-19 symptoms six months later, suggesting "long haulers" might be more prevalent than previously thought. To date, this is the largest study with the longest follow-up. Follow-up visits were done, and the median follow-up time was 186 days.

Aside from lingering symptoms, study authors discovered patients who had suffered from more severe COVID infections are more likely to now have impaired lung function. All were questioned face-to-face and they also underwent medical examinations, including physical examinations and a six-minute walking test to examine their endurance levels. From the over 1,700 patients involved, 390 also completed further testing to measure lung function. The median age of the eligible patients was 57.

The researchers found that the most reported symptoms such as fatigue, tiredness after exertion, and cognitive dysfunction often referred to as brain fog, lasted for at least six months.

According to the scientists, the most common symptom to persist was muscle weakness (63% of cases), with patients also frequently experiencing sleep difficulties (26%).

The authors also mentioned that some patients went on to develop kidney problems post-Covid-19 discharge.

After multivariable adjustment, patients showed an odds ratio (OR) 1.61 (95% CI 0.80-3.25) for scale 4 versus scale 3 and 4.60 (1.85-11.48) for scale 5-6 versus scale 3 for diffusion impairment; OR 0.88 (0.66-1.17) for scale 4 versus scale 3 and OR 1.77 (1.05-2.97) for scale 5-6 versus scale 3 for anxiety or depression, and OR 0.74 (0.58-0.96) for scale 4 versus scale 3 and 2.69 (1.46-4.96) for scale 5-6 versus scale 3 for fatigue or muscle weakness. It is also limited to being a single-centred study of exclusively Chinese patients. It is one of the few studies to trace long-term symptoms of infection of COVID-19.

Many more researchers are now launching follow-up studies of people who have been infected with COVID-19.

In the United Kingdom, the Post-Hospitalisation COVID-19 Study (PHOSP-COVID) aims to follow 10,000 patients for a year, analysing clinical factors such as blood tests and scans, and collecting data on biomarkers.

The study performed several exams on the COVID patients to see how they were faring after their hospital stay.

The long-term health consequences of Covid-19 remain largely unclear. "Our work also underscores the importance of conducting longer follow-up studies in larger populations in order to understand the full spectrum of effects that COVID-19 can have on people", says Professor Bin Cao from National Center for Respiratory Medicine, China-Japan Friendship Hospital, and Capital Medical University in a media release. Of the 822 patients who had normal kidney function when they entered the hospital, the study reveals 107 (13%) suffered from reduced organ function during their follow-up six months later.
