Covid-19 spread among white-tailed deer in US causes concern over new variants
The coronavirus disease (Covid-19) pandemic has infected millions of people around the world. In the two years since it emerged, the virus has mutated, become more powerful, and led to waves of infections that initially resulted in a large number of deaths.
That’s why health experts around the world are advising people to minimize physical contact, wear protective gear like masks and face shields, and sanitize their hands and wherever they go to protect themselves from the virus.
But now, a new development is worrying doctors and experts in the U.S. — the coronavirus has been found in white-tailed deer in Iowa. Even more dangerous, according to health care experts, is that there are 30 million such animals, and they often come into contact with humans.
When scientists sifted through frozen samples of deer killed by hunters or cars in 2020, they found that 60 percent of them were infected with the coronavirus, according to a New York Times report.
“It’s fantastic,” Penn State microbiologist and infectious disease expert Vivek Kapur told The New York Times. To date, his team has analyzed samples of 4,000 dead deer and mapped the location of each infected animal. “It’s totally crazy. It looks like it’s everywhere,” he said.
Adaptation of animals is one way in which new variants may emerge. “This is the number one concern in America right now,” Dr. Kathy Barton Bellavish, director of the Centers for Disease Control and Prevention’s (CDC) Office of Unified Health, told The New York Times.
Last August, the United States reported its first case of Covid-19 in a deer. But the new finding has reignited concerns about a new wave of infections believed to be spread by animals. The USDA has previously reported Covid-19 in animals including dogs, cats, tigers, lions, snow leopards, otters, gorillas and minks.
Minks have attracted a lot of attention, leading to mass culling of the animals.
Scientists have long feared that the infection could spread from animals to humans, but sought more research before drawing any conclusions. In the latest case from Iowa, they said those who ate cooked venison had a lower risk of contracting the Sars-CoV-2 virus than those who came into contact with feces and feces. In addition, the virus can be transmitted in lions, which kill deer by biting into their windpipe or nose and mouth.
The New York Times, citing scientists, said early research suggested cows and pigs had the lowest risk of contracting the coronavirus. But in the deer’s body, which shows few symptoms, it can turn into a pathogen capable of infecting the livestock.
According to the CDC, the risk that animals will transmit Sars-CoV-2, the virus that causes Covid-19, to humans is low.

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.
