The pandemic has provided evidence suggesting that viral infections may reawaken dormant cancer cells in patients who had them before the infection. Doctors are studying this potential link between viruses and cancer reactivation.

CRISPR, short for Clustered Regularly Interspaced Short Palindromic Repeats, is an immune system evolved in bacteria to defend against viral threats. It functions by snipping and storing fragments of viral DNA in the CRISPR region for future defense.

The gut contains trillions of microorganisms, including bacteria, viruses, and fungi. The article explores the role and presence of these microorganisms within the human gut.

Necropsy reports from sloths imported by a planned Orlando tourist attraction in Florida revealed animals stressed and infected with bacteria, parasites, and viruses. Scientists warn that the wildlife trade poses a risk to human health, as shown by the mass sloth deaths.

A study reveals vitamin D2 supplements may decrease levels of vitamin D3, the more effective form of vitamin D, which plays a unique role in immune system function against viruses and bacteria. Researchers are reconsidering vitamin D3 as the preferred supplement choice.

Scientists developed a virus-fighting plastic film with microscopic pillars that physically destroy viruses by stretching them until they burst. The material disabled 94% of virus particles in lab tests within an hour, offering a chemical-free disease prevention method.
