Experiencing dry, itchy eyes and blurred vision and thinking it is just because of prolonged exposure to digital screens? These symptoms could also be COVID-19 sequelae that you should be aware of. An ophthalmology team from CUHK has found that post-COVID-19 patients have a higher risk of developing dry eye disease, and that one in five people who have had COVID-19 suffer from at least one symptom related to dry eye disease.

The Microbiota I-Centre of CUHK has identified distinct gut microbiome profiles that can characterise “long COVID”. This is the world’s first study to demonstrate gut microbiota as a key determinant of long COVID. These distinct gut microbial signatures can be used as a diagnostic tool and to guide therapy.

People who have recovered from a COVID-19 infection may suffer from poor memory, hair loss, difficulty in sleeping and other long-term consequences, which are commonly known as “long COVID”. CU Medicine has found that patients with long COVID have a less diverse gut microbiome, indicating that gut microbiome composition may be linked to the risk of developing long COVID, while gut microbiota modulation could facilitate timely recovery and reduce the burden of post-acute COVID-19 syndrome.
