Pandemic Changed Global Flu Spread—But It’s Back
United States: People of the world have become less infected by seasonal flu in the pandemic because travel and other social activities were restricted. However, some strains of the virus remained active and mutated in parts of the world with less strict measures mostly the tropical regions of South and West Asia. Seasonal flu transmission is very dependent on social interaction and includes air travel and the appearance of new strains not covered by earlier infections or jabs, as reported by scitechdaily.com
Reduced Flu Strains During COVID-19 Lockdowns
Because COVID-19 control measures in 2020 included, inter alia, lockdowns, mandatory social distancing, face masks, and travel restrictions, these NPIs caused major interruptions to influenza transmission and its evolution. Consequently, such contingent illnesses as seasonal FLU A subtypes H1N1 and H3N2, as well as B subtypes Victoria and Yamagata, reduced significantly.
Study Highlights

Zhiyuan Chen and other scientists in this study ascertained the impact of these changes towards the transmission, spatiotemporal distribution and evolutionary trajectories of seasonal influenza lineages. Applying the phylodynamic method and performing epidemiological, genetic, and international travel analysis of data obtained before, during, and after the COVID-19 pandemic, the researchers identified that the beginning of the pandemic changed the intensity and structure of global influenza transmission.
Despite a decrease in influenza cases globally during the time of pandemic uptick, in SA and WASH, the A and the B/Victoria lineages respectively circulated with less restrictive measures compared to other regions during the pandemic. That circulation provided them as significant evolutionary ancestors, or ‘phylogenetic trunk position’, of influenza viruses throughout the pandemic phase.
Flu Bounces Back, But One Lineage May Be Extinct
By March 2023, the number of distinct influenza lineages circulating in the population was already back to predemographic levels, as long-haul air traffic resumed, indicating that the virus is adaptive and does not suffer from long-term disruption; it merely has to wait for air travel to revive so that it can spread its lineages. It may also be noted, however, that the current study reveals that since the beginning of the pandemic there was no observation of the influenza B/Yamagata lineage further cementing the argument that the lineage has possibly gone extinct at some point, as reported by scitechdaily.com
“The study by Chen et al. further reinforces that nonpharmaceutical interventions can be incredibly effective in disrupting viral transmission, pathogen diversity, and antigenic evolution, and are arguably more effective than vaccine efforts alone,” write Pejman Rohani and Justin Bahl in a related Perspective.

HIV Treatment Linked to Risk of Early Knee Osteoarthritis: A New Health Concern

HIV treatments have been transformative, turning what was once a fatal diagnosis into a manageable condition. However, as people with HIV live longer and healthier lives, researchers are uncovering potential long-term side effects of antiretroviral therapy (ART). One emerging concern is the increased risk of developing early-onset knee osteoarthritis in individuals undergoing HIV treatment.
Understanding the Connection
Osteoarthritis (OA) is a degenerative joint disease characterized by the breakdown of cartilage and underlying bone in joints, leading to pain, stiffness, and decreased mobility. While OA is traditionally associated with aging, recent studies suggest that individuals on ART may face a higher likelihood of developing knee osteoarthritis earlier in life.
The exact mechanisms are still under investigation, but researchers hypothesize that inflammation, changes in bone metabolism, and weight fluctuations linked to HIV and its treatment may contribute to joint degeneration. Certain ART drugs are also known to affect lipid levels and fat distribution, which can indirectly impact joint health.
Key Risk Factors
- Chronic Inflammation:
Even with effective ART, individuals with HIV often experience low-grade chronic inflammation, which can accelerate joint damage. - Changes in Body Composition:
ART has been linked to fat redistribution and metabolic changes, potentially increasing stress on weight-bearing joints like the knees. - Age and Lifestyle:
As the HIV-positive population ages, age-related wear and tear on joints combines with the effects of long-term ART, compounding the risk.
Implications for Patients and Healthcare Providers
The link between HIV treatment and early knee osteoarthritis highlights the importance of proactive joint health management. Patients and healthcare providers should consider the following strategies:
- Regular Monitoring: Periodic assessment of joint health can help identify early signs of osteoarthritis.
- Physical Activity: Low-impact exercises, such as swimming or cycling, can strengthen muscles around the knee and reduce joint strain.
- Weight Management: Maintaining a healthy weight can alleviate pressure on the knees.
- Medication Review: Physicians might consider evaluating the ART regimen for drugs with lower metabolic side effects.
A Call for Further Research
While the evidence suggests a link between HIV treatment and early knee osteoarthritis, more research is needed to confirm these findings and uncover the underlying mechanisms. Such studies could pave the way for targeted therapies or preventive measures to address this emerging health concern.
FAQs
1. Can all antiretroviral drugs cause knee osteoarthritis?
Not all ART drugs are linked to knee osteoarthritis, but some may contribute to metabolic changes that increase the risk.
2. What symptoms of knee osteoarthritis should I watch for?
Common symptoms include knee pain, stiffness, swelling, and difficulty in movement, particularly after periods of rest.
3. Are there ways to prevent knee osteoarthritis if I’m on HIV treatment?
Yes, regular exercise, maintaining a healthy weight, and working with your healthcare provider to monitor joint health can reduce the risk.
4. Should I stop my HIV medication if I’m worried about osteoarthritis?
No, never stop or change your medication without consulting your doctor. Your healthcare provider can help balance your HIV treatment with strategies to protect your joint health.
5. Is early knee osteoarthritis common in people without HIV?
Early-onset knee osteoarthritis can occur in the general population, but people undergoing HIV treatment may have unique risk factors that increase their susceptibility.
By understanding the connection between HIV treatment and knee osteoarthritis, patients and healthcare providers can work together to minimize risks while continuing effective HIV management. As science advances, we can hope for even better strategies to ensure long-term health and quality of life for those living with HIV.

90-Day No-Sugar Challenge Brings Major Health Gains, Say Doctors
90-day no-sugar challenge, no-sugar challenge benefits, health gains from no sugar, sugar-free diet, improved energy and weight loss.

In today’s fast-paced world, where sugary treats are readily available, taking on a no-sugar challenge can feel daunting. However, health experts emphasize the significant benefits of cutting out added sugars for even 90 days. The “90-day no-sugar challenge” has become a popular movement among health-conscious individuals, and doctors are applauding its positive impact on overall well-being.
Why Say No to Sugar?
Sugar consumption is often linked to various health problems, including weight gain, diabetes, heart disease, and even mental health issues like depression. According to the World Health Organization (WHO), added sugars should make up less than 10% of daily caloric intake, but many people far exceed this limit due to hidden sugars in processed foods.
By eliminating added sugars for 90 days, individuals can break free from sugar cravings and reset their taste preferences, paving the way for healthier eating habits.
The Benefits of the 90-Day No-Sugar Challenge
- Improved Energy Levels
Reducing sugar intake helps stabilize blood sugar levels, preventing energy crashes. Participants often report sustained energy throughout the day. - Weight Loss
Cutting out sugary drinks and snacks can lead to a calorie deficit, making it easier to shed excess weight. - Better Heart Health
Lower sugar intake is linked to reduced risks of high blood pressure and cholesterol, which are major contributors to heart disease. - Enhanced Mental Clarity
Many people experience better focus and reduced brain fog when they eliminate sugar from their diet. - Healthier Skin
Sugar can accelerate skin aging and cause breakouts. Removing it often leads to clearer and more youthful skin.
What to Expect During the Challenge
The first week may be the toughest, as the body adjusts to the absence of sugar. Symptoms like fatigue, headaches, and cravings are common. However, by the second or third week, most participants notice a significant improvement in their overall well-being.
Doctors recommend planning meals in advance, choosing whole, unprocessed foods, and replacing sugary snacks with healthier alternatives like fruits, nuts, and seeds.
Tips for Success

HPV Vaccine Equally Important for Men: Medical Experts Stress Its Role in Public Health

When discussing vaccines for preventing serious diseases, the human papillomavirus (HPV) vaccine is often associated with women’s health, especially in preventing cervical cancer. However, medical experts increasingly emphasize that the HPV vaccine is equally important for men. Protecting men not only safeguards their health but also significantly reduces the overall transmission of HPV, benefiting public health on a larger scale.
What Is HPV?
HPV is one of the most common sexually transmitted infections (STIs) worldwide. It includes over 100 different strains, some of which can cause warts, while others are linked to cancers such as cervical, anal, penile, and throat cancers. HPV infections often go unnoticed, as they frequently show no symptoms but can lead to serious health complications over time.
Why Should Men Get the HPV Vaccine?
- Cancer Prevention for Men:
While cervical cancer in women is widely recognized as a consequence of HPV, men are also at risk. HPV-related cancers, such as penile, anal, and oropharyngeal (throat) cancers, are on the rise among men. Vaccination significantly lowers this risk by preventing the strains most commonly linked to these cancers. - Reducing Transmission:
Men can unknowingly transmit HPV to their partners, perpetuating the cycle of infection. Vaccinating men helps create herd immunity, reducing the overall prevalence of HPV in the population. - Preventing Genital Warts:
Certain HPV strains cause genital warts, which, while not life-threatening, can be distressing and require medical treatment. The HPV vaccine protects against these strains, sparing individuals from the physical and emotional burden of such infections.
When Should Men Get the HPV Vaccine?
Health authorities, including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), recommend the HPV vaccine for boys and girls starting at ages 11-12. The vaccine is most effective when administered before an individual becomes sexually active. However, it can still benefit those up to the age of 26, and in some cases, even older individuals may consider vaccination after consulting a healthcare provider.
Addressing Misconceptions
Despite its proven benefits, many men remain unaware of the importance of the HPV vaccine. This is partly due to the misconception that HPV primarily affects women. Experts urge healthcare providers to discuss the vaccine’s benefits with male patients and their families to dispel myths and increase vaccination rates among men.
Public Health Implications
Widespread vaccination among both genders creates a ripple effect, reducing the overall burden of HPV-related diseases. It also leads to lower healthcare costs and improves quality of life for millions. Countries that have adopted gender-neutral HPV vaccination programs have already reported significant declines in infection rates.
Final Thoughts
The HPV vaccine is not just a women’s health issue—it’s a critical tool in protecting everyone. Men play an equally important role in preventing the spread of HPV and reducing the risks associated with it. By making vaccination a priority for all genders, we take a vital step toward a healthier, HPV-free future.
Talk to your doctor today about the HPV vaccine—because prevention is better than cure, and your health matters.
