Vitamin D: Cost-Effectively Overcoming Infections and Chronic Diseases
The prevalence of chronic diseases increases with age, especially in those with co-morbidities. The two most common denominators are the high prevalence of vitamin D deficiency and low concentrations of angiotensin-converting enzyme receptor-2 (ACE2). Whether vitamin D deficiency initiates or aggravates chronic diseases is unclear: the likelihood is both. Hypovitaminosis D negatively affects all body systems, especially the musculoskeletal and immune systems. Many chronic conditions and infections can be minimized using the right dose of vitamin D supplements administered at the right frequency (daily or once weekly) or direct sun exposure to one-third of the skin between 10:30 AM and 1:30 PM, in summer like sunlight, for 20 to 60 minutes depending on the skin tone. It is advisable to wear sunglasses and a brimmed hat to protect one’s eyes and face. Maintaining the population serum 25(OH)D concentration above 40 ng/mL (i.e., sufficiency) ensures a better immune system, minimizing symptomatic diseases and reducing infections and chronic diseases. The best clinical outcome and longevity are expected from maintaining the serum 25-hydroxyvitamin D concentrations between 50 and 80 ng/mL.

Palestinian Citizens of Israel's Compliance with COVID-19 Regulations
With the continuing surge of COVID-19 waves well into 2022, it has become increasingly clear that vaccination alone, which many expected would make the need for behavioral changes redundant, is not sufficient to restrain the spread of the virus and that the adoption of the behavioral changes recommended by public health services worldwide, in particular social distancing and mask wearing, will still be in the future an indispensable part of the strategy to restrict the contagion.
