Both bacterial and viral eye infections are contagious (usually from person to person). The only way to tell the difference between bacterial and viral eye infections is an eye exam from an ophthalmologist.
Most eye infections are viral, and are very infectious.
Bacterial eye infections are less common and are treated with antibiotic drops and pills, and treatment of the underlying cause, such as chronic blepharitis or lid infection.
Viral eye infections are treated with artificial tears, mild steroid drops, and drops to prevent redness and itching. Special care is necessary to avoid giving the infection to others, including careful hand washing, throwing away eye make-up and contaminated contact lenses, and trying not to rub the eyes.
Be careful of "persistent" or "chronic" eye infections — they may be something else entirely, such as chronic inflammation from blepharitis or dry eye.
Don't stay on steroid drops for more than a few weeks. I just saw a patient who had been treated with steroid eye drops for a chronic lid infection from his primary care doctor. The patient wasn't getting better, so he kept re-filling the prescription, and after six weeks of (ineffective) treatment, he had steroid induced glaucoma in both eyes (and a stye which wouldn't go away)
"Four million people died in 2015 as a result of being too tubby, struck by cancer, heart disease, diabetes and other killer conditions," reports The Sun. This is based on a global study that looked at how the proportion of people who are overweight and obese has changed over time. This was determined by recording body mass index (BMI), where a BMI of 25-29.9 means being overweight and 30 or above is being obese. Researchers then assessed the link between having an unhealthy BMI and health outcomes including cardiovascular disease, diabetes and cancer. It found that, despite public health efforts, obesity is on the rise in almost every country and in both adults and children. Prevalence has doubled in most countries over the past 30 years. Researchers also estimated that having a high BMI accounted for 4 million deaths globally, 40% of which occurred in people who were overweight but not yet obese. This demonstrates that being overweight may almost be as risky to health a...
