Five years ago today the term #LongCovid was first used as a Twitter hashtag. A single tweet by a patient linked together a growing, grassroots movement of people who weren't recovering from Covid. Across the world, we were fighting for recognition and studying our own disease Image

I feel strange posting this again after five years of fighting, suffering, and a global, grassroot mobilization of Covid survivors, who changed how Covid was understood and communicated to the public
Far from being a short, respiratory illness in most, dangerous only for the "old and frail", as said in early guidelines, Covid was a prolonged, multi-system disease, which could be severe and even fatal also in the "young and healthy": #LongCovid

sciencedirect.com/science/articl…
In early to mid 2020, a grassroots, international, collaborative movement of Covid survivors brought into light the severity, variability and prolonged nature of symptoms and sequelae, many of which remained beyond the medical gaze at the time

#LongCovid

wellcomeopenresearch.org/articles/5-224
#LongCovid was first identified, named, defined by patients finding one other on social media like Twitter in early/mid 2020. By August 2020, Long Covid was openly recognised by WHO after intense advocacy-research which reached the highest echelons of policymaking
By mid 2020 to early 2021, #LongCovid was entering the biomedical literature. Guidelines were written. The mechanisms underlying the disease, the symptoms, the epidemiology were being described, studied, elucidated. Patients were at the forefront of advocacy and discovery
As of 2025, Covid and #LongCovid are among the most studied diseases in medical history, especially given the short timeframe. Thousands and thousands of scientific publications exist on LC, which show prolonged pathology and sequelae in basically all organs and body systems
But the Covid pandemic remains one of the deadliest pandemics in recorded history and a mass disabling event. 20 to 30 millions were estimated to have died from Covid as of 2023. Hundreds of millions are estimated to have experienced LongCovid

I wrote again what I wrote 1 year ago today, the exact words: Too many have died. Too many remain with no access to medical care. Trials are lagging behind. There is no cure. People are losing their lives, livelihood, family, health and support networks.
We are still fighting for full recognition, for dignity, for treatments, for safety. The pandemic is not over, new variants are rising, people lack appropriate access to care. I am grateful for the massive wave of research, and fast recognition in 2020-1. Yet, so much suffering
I am grateful that a name created by a person living with the disease has become in so many contexts and publications the official name of the disease. A community carried us there. A collective movement of patients, a collective effort empowers a patient community #LongCovid Image

On this day, I want to express my gratitude and respect to all patients, advocates, patient-researchers and allies who brought us here. I also want to remember the lives lost, the pain, the suffering, the lack of care, the fight. Thinking about all of you. Thanks

"I was still ok 10 min before the match"

There are concerns over a possible gastrointestinal virus spreading at the top Australian Open in elite tennis. Star Flavio Cobolli suffered a shocker early defeat, while being debilitated by sudden symptoms.

ilgiornale.it/news/tennis/vi…
Another player apparently affected is Luciano Darderi, who still managed to win his match, as he started to feel really unwell only towards the end. His GI symptoms were reportedly aggravated by medication he had to take for some injury.
World number 22 Cobolli admitted he was so ill he would have withdrawn, had the tournament been less prestigious. He started to feel unwell just before or at the beginning of his match, which he lost in the end.

"No further delay should be acceptable."

Proud to co-author this #LongCovid declaration to demand urgent action to fully recognise, treat and prevent Long Covid

"Long COVID is a new complex chronic condition caused by SARS-CoV-2. Born in 2020 from the lived experience of patients, the term broke the early myth that COVID-19 was either a brief mild illness or a rapidly fatal disease."
"[the term #LongCovid] sparked a global grassroots movement demanding recognition and research. Long COVID is a vascular, chronic multisystemic condition caused by a virus that challenges medicine and public health in unprecedented ways."

There are concerns about a "mysterious illness" going through the pelaton at the top cycling event Tour de France. Several racers were reported to be affected already days ago. Since then, star M. van der Poel has withdrawn with pneumonia while R. Evenepoel left feeling "empty" Image
One of the most prominent racers affected by the "mysterious illness" was superstar and current Tour leader Tadej Pogačar, who lamented cold symptoms but remains in the race. Van der Poel also had cold symptoms, which has now progressed to pneumonia

rmcsport.bfmtv.com/cyclisme/tour-…
Tadej Pogačar told reporters on Sunday "Am I sick? Thanks for checking in, actually I'm better, it's almost over" He added: "I have a bit of a runny nose, a bit of a cough, but I'm not really sick. It's just a bit of a pain in the *ss."
Pogačar currently remains Tour leader

Biopsies of five patients with myocarditis in #LongCovid showed disruption of mitochondrial integrity in the heart. This research was replicated in mice and shed light on the profound cardiovascular impact of SARS-CoV-2 infection on cardiovascular health
sciencedirect.com/science/articl…
The team's "investigation provides histopathological and electron microscopic analyses from endomyocardial biopsies of five patients who experienced various post-COVID-19 cardiovascular outcomes." such as myocarditis (inflammation of the heart muscle)
"Electron microscopy revealed widespread mitochondrial disorder and the presence of myofilament degradation within the cardiomyocytes from the patients.

Similar mitochondria disorganization were found in SARS-CoV-2 infected mice."
