Signs You Have COVID, Says Dr. Sanjay Gupta

CNN's resident brain surgeon Dr. Sanjay Gupta is warning about the BA.2 Omicron subvariant, and how fast it is spreading. "According to the latest figures from the CDC, [BA.2] now makes up about 11.6% of Covid cases in the US; the week before, 6.6%. BA.2 is the dominant variant in Denmark, the United Kingdom, India, South Africa and more than a dozen other countries. According to the World Health Organization, studies estimate it is 30% more contagious than the original Omicron (BA.1)." Here are five signs you have COVID-19, according to Dr. Gupta. Read on—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.


Neurological Issues

Many people are experiencing neurological issues after being infected with COVID-19. "Regardless of how exactly the virus harms the body, we now know that the impact of COVID-19 on the nervous system can be more significant and lasting than the transient loss of taste and smell that many of the first infected patients described," says Dr. Gupta. "It can have devastating short- and long-term neurological complications — from delirium, depression and "temporary brain dysfunction" to headaches, brain inflammation, brain bleeds and clots, nerve damage and life-threatening meningitis in both the young and old."


Signs of Long COVID

"Many Americans are enduring the lingering effects of a past infection, battling health conditions like fatigue, brain fog, shortness of breath, cardiac issues," says Dr. Gupta. "The list of long Covid symptoms is lengthy and varied; there are no answers as to who and why, nor are there easy, one-size-fits-all treatments."


Cardiovascular Complications

Long-term cardiovascular issues are a particularly worrying symptom of the virus. "We are in the early days of this disease, but I was particularly struck by the recent paper indicating a previous Covid infection being a significant risk factor for future heart problems," says Dr. Gupta.

Infected? You May Feel This, and Stay Home For At Least Five Days

"The chance that you're still infectious drops as time goes on," says Dr. Gupta. "The longer you stay isolated, the less likely you'll expose someone else to the virus. Ten days after testing positive, the percentage of people still contagious is estimated to be about 5%, according to researchers at the UK Health Security Agency. However, at day five, the end of the CDC isolation period, a significant percentage of people (31%) are still contagious. By day seven, the percentage of people still contagious drops by half — to about 16%." Also: "Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea"

…And Then Wear a Mask For Another Five Days

If you have been infected with BA.2 and are coming out of isolation, wear a mask for another five days as an extra precaution. "While the CDC surprisingly still recommends three ply-cloth masks, many experts say they aren't adequate, especially given how easily Omicron spreads: up to three times faster than Delta, according to recent research from Denmark," says Dr. Gupta. "Erin Bromage, an associate professor of biology at the University of Massachusetts Dartmouth, reminds us that this is primarily an airborne virus and not spread so much by droplets, as happens with flu. Citing data from the American Conference of Governmental Industrial Hygienists, Bromage says a cloth face covering has 75% inward and outward leakage. Compare that with an N95 or KN95, which are excellent at filtering not only large droplets but up to 95% of particles in the air."

When Should I Take Creatine?

Creatine is probably the most well-researched supplement on the market today. Numerous studies have found positive adaptations in strength, power and muscle mass thanks to creatine supplementation—especially when it's combined with resistance training. Although the benefits of creatine are well-known to lifters, the best time to take it isn't common knowledge. Which leads us to some important questions:     Does an optimal time for consuming creatine exist?     If it does, should you take it before or after your workout? According to a new study published in the Journal of Exercise and Nutrition, the timing of creatine ingestion does indeed play a role in getting bigger and stronger. Creatine supplementation before resistance training increases muscular strength and lean muscle mass. Interestingly, taking creatine immediately after lifting weights results in greater muscle growth than taking it immediately before. However, in terms of strength gains, no difference betw

Best Smoothie Habits for Weight Loss, According to Dietitians

When it comes to trying to lose weight , most of us are rather poor math students. We mess up the addition and subtraction all the time.
