Explained: When was IHU variant first discovered and its spread
In the spread of Omicron coronavirus variants, the discovery of a new strain that emerged in France has attracted the attention of experts from all over the world. It was named “IHU”, which caused concerns about a new wave of infections.
This variant has 46 mutations and 37 deletions in its genetic code, which is more than Omicron. Many of these affect the spike protein.
This variant is a sub-family of B.1.640, and its discovery was announced by researchers at Méditerranée Infection in Marseille, which is part of the French Hospital University (IHU, or University Hospital Research Institute)-hence the name. It has been classified as B.1.640.2. When was IHU first discovered?
According to Forbes, the first known case of a variant of IHU was discovered in mid-November 2021. This predates Omicron’s official discovery (November 24).
The new variant was discovered in a French man returning from Cameroon, Africa (Omicron was also found on the continent). He began to develop respiratory symptoms and was tested for Covid-19. The sample returned positive and there is a B.1.640.2 variant.

Since then, 11 more cases have been reported in the same geographic area in southwestern France.
More information on the B.1.640 pedigree
The pedigree is not new. According to data from Exposure.info, an open source database of Covid-19 resources and epidemiological data, B.1.640 was first detected on January 1, 2021. It said that so far, 400 infections related to this lineage have been identified.
The outbreak information further reported that B.1.640 cases were detected in as many as 19 countries/regions, including one from India. The Indian case was detected from 89,763 sequences reported in the global database.
France (287) reported the most cases of the B.1.640 variant, followed by Congo (39), Germany (17) and the United Kingdom (16).
Do IHU variants spread faster?
So far, only a dozen cases have been reported in France. No other countries have found any new cases of new variants. It is not clear whether B.1.640.2 is stronger or spread faster than other previously known coronavirus strains.
This is why the World Health Organization (WHO) has not yet considered this variant of IHU as a variant of interest, a variant of interest, or even a variant under investigation.
Based on a preprinted paper published on MedRxiv, it is too early to speculate on the virological, epidemiological or clinical characteristics of this variant of IHU.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine
Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.
When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.
While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress.

Why recovery is key for muscle growth
According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.
Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.
Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.
Role of overtraining syndrome and deload weeks
Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.
Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.
Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
