Six feet may not be far enough to stop transmission of COVID-19: experts
When inside, it might be a good idea to take a few more steps.
Experts on Tuesday said they believed that the six foot distance recommended by the World Health Organization (WHO) might not be enough to limit COVID-19 transmission.
In a perspective articles published in the journal Science, three experts write that aerosol particles can accumulate and remain infectious in the air in the room for hours, while being easily inhaled deeply into the lungs.
“More and more evidence for SARS-CoV-2 suggests a 6 foot WHO recommendation might not be sufficient in many indoor conditions where aerosols can remain in the air for hours, accumulate over time, and follow the air flow at a distance further than 6 feet, “they said.
Chia Wang from National Sun Yat-sen University in Taiwan, and Kimberly Prather and Dr. Robert Schooley of the University of California, San Diego, said that most of the spread of COVID-19 seems to occur through air transmission. aerosol. They added that the transmission was produced by asymptomatic individuals during breathing and speaking.
On Tuesday, experts said that for the community to return to normal, steps must be implemented to reduce aerosol transmission, which includes universal use of masks – in addition to widespread testing. They believe the two practices can help identify and isolate infected individuals without symptoms.
“It is very important to wear masks in locations with conditions that can accumulate high concentration of viruses, such as health care settings, airplanes, restaurants and other crowded places with reduced ventilation,” they added.
The perspective article states that countries – such as Taiwan, Hong Kong, Singapore, and South Korea – have implemented universal masking and are most effective in reducing the spread of COVID-19.
WHO’s six foot social distance guideline is based on a study of respiratory droplets in the 1930s. However, technology did not exist at the time to detect tiny aerosol particles, experts said.
Smaller aerosols will evaporate faster than they can spend, they added. Therefore, they can be influenced by air currents, which can transport them from a long distance and cause them to stay in the air for hours.
“A lot of evidence has shown respiratory virus aerosol transmission,” Prather tells WebMD. “This particular virus, a lot of evidence is on the rise.”
This month, a learn by scientists in Hong Kong found that using surgical masks can reduce the rate of non-contact transmission through respiratory droplets or air particles by up to 75 percent.

Hermann’s Tortoise Lifespan: How to Ensure a Long, Healthy Life
Ensuring a long and healthy life for your Hermann’s Tortoise requires a combination of proper care, nutrition, and habitat management. Hermann’s Tortoises, known for their charming personalities and distinctive shells, can live for several decades with the right conditions. Understanding their needs and providing a suitable environment is key to helping them thrive. Here’s how you can support your Hermann’s Tortoise in living a long, happy life.
Creating an Optimal Habitat
One of the most critical factors in promoting the longevity of your Hermann’s Tortoise is the creation of a suitable habitat. Providing an environment that mimics their natural surroundings is essential for their overall health. An appropriate habitat helps prevent stress and supports their well-being. For detailed guidance on setting up an ideal habitat, including specific requirements for outdoor enclosures, visit this comprehensive guide on Habitat for Hermann’s Tortoise.
- Outdoor Enclosure: Hermann’s Tortoises thrive in outdoor enclosures that provide ample space to roam, bask, and forage. An outdoor setup should include a secure, predator-proof area with access to natural sunlight. Incorporate areas for basking and shade to allow the tortoise to regulate its body temperature. Additionally, include plants, rocks, and hiding spots to simulate their natural habitat and encourage natural behaviors.
- Indoor Habitat: If an outdoor enclosure is not feasible, an indoor habitat can also support a long lifespan if set up correctly. Use a large, well-ventilated enclosure with appropriate heating and UVB lighting. Provide a substrate that allows for burrowing and offer various hiding spots and enrichment items.
Diet and Nutrition
A balanced diet is vital for maintaining the health and longevity of your Hermann’s Tortoise. They are primarily herbivores, and their diet should reflect their natural feeding habits.
- Leafy Greens: Offer a variety of leafy greens such as kale, collard greens, and dandelion greens. These vegetables provide essential vitamins and minerals that support overall health.
- Vegetables and Fruits: Supplement their diet with other vegetables like carrots, squash, and bell peppers. Fruits should be given in moderation due to their high sugar content.
- Calcium and Supplements: Provide a calcium supplement to support shell and bone health. A cuttlebone or powdered calcium can be added to their food. Ensure that they also have access to fresh, clean water at all times.
Regular Health Checks
Routine health checks are essential for early detection of potential health issues. Regular veterinary visits help ensure your tortoise remains in optimal condition and addresses any health concerns promptly.
- Observation: Monitor your tortoise’s behavior and physical condition regularly. Changes in appetite, weight, or activity level can indicate health problems.
- Preventative Care: Schedule annual check-ups with a veterinarian experienced in reptile care. Regular exams help catch any issues early and keep vaccinations and other preventative treatments up to date.
Environmental Enrichment
Providing environmental enrichment helps keep your Hermann’s Tortoise mentally stimulated and active. Enrichment can reduce stress and prevent boredom, contributing to a better quality of life.
- Foraging Opportunities: Hide food items around the enclosure to encourage natural foraging behavior. This not only provides mental stimulation but also mimics their natural hunting practices.
- Variety: Change the layout of their enclosure periodically and introduce new objects or plants to keep their environment interesting and engaging.
Conclusion
By focusing on creating the right habitat, providing a balanced diet, ensuring regular health checks, and offering environmental enrichment, you can significantly enhance the lifespan and well-being of your Hermann’s Tortoise. For further details on creating an ideal habitat, including tips for designing an outdoor enclosure, refer to this helpful guide on Habitat for Hermann’s Tortoise. Implementing these practices will help ensure that your tortoise enjoys a long, healthy life.
