Highly transmissible Omicron sub-variant now in 57 countries, warns WHO
A sub-variant of a fast-spreading and highly mutated strain of the coronavirus, Omicron, has now been identified in as many as 57 countries, the World Health Organization (WHO) warned on Tuesday. A key reason for concern is that some studies have suggested that this Omicron sub-variant may be more contagious than the original version, which quickly became the dominant global variant in just 10 weeks after it was first detected in southern Africa.
In its most recent weekly epidemiology update, WHO explained that Omicron, which accounted for more than 93% of all coronavirus specimens collected in the past month, had several sublineages: BA.1, BA.1.1, BA.2 and BA.3.
BA.1 and BA.1.1 were the first discovered Omicron sub-variants and still account for more than 96% of all Omicron sequences uploaded to the GISAID Global Science Program. Since then, however, there has been a marked increase in cases involving the BA.2 sub-variant, which counts several different mutations from the original mutation—including one on the spike protein on the surface of the virus, which is a The key to entering human cells.
“To date, 57 countries have submitted BA.2-designated sequences to GISAID,” WHO said, adding that in some countries the subvariant now accounts for more than half of all Omicron sequences collected.
WHO acknowledges that little is currently known about the complete extent of the differences between all subvariants; however, detailed studies could reveal their characteristics – including transmissibility, immune evasion and virulence.
One of the World Health Organization’s top experts on Covid-19, Maria Van Kerkhove, told reporters yesterday that there was very limited information on the sub-variant, but some preliminary data suggested that the growth rate of BA.2 was “slightly higher than that of BA.1”.
Several recent studies suggest that BA.2 is more contagious than the original Omicron.
In general, Omicron is known to cause less severe disease than previous coronavirus variants such as Delta that wreaked havoc. So far, Van Kerkhove said, “there is no indication that the severity of the BA.2 subvariant has changed.”
However, she stressed that despite the strain, Covid-19 is still a dangerous disease and people should work hard to avoid contracting it.
“We need people to realize that this virus is continuing to spread and it is continuing to evolve,” she said. “Whatever variant is spreading, it’s very important that we take steps to reduce exposure to this virus.”

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.
