You may be used to receiving COVID-19 vaccines and boosters. You may also feel something familiar when putting on a mask in crowds. These actions are common ways to help prevent COVID-19 infection.
Recent research suggests another option for protection: an over-the-counter nasal spray. The study found that azelastine, an OTC nasal spray, could reduce the risk of contracting COVID-19. Researchers also found that azelastine may protect against other respiratory viruses.
Imagine a mutant monster that constantly adapts to survive every attack. Each time a weapon strikes it, the creature evolves new defenses. When missiles hit, it grows a thick, hardened shell. When poison gas spreads, it forms lung filters to breathe clean air. When bombs fall, it learns to teleport out of range.
This nightmare creature mirrors a growing real-world threat: antimicrobial resistance. As bacteria face repeated exposure to antibiotics, they mutate to defend themselves. A new World Health Organization report shows antibiotic resistance rising worldwide. In 2023, one in six common bacterial infections resisted treatment. Resistance increased 40% between 2018 and 2023. The data show a steady 5 to 15% rise each year.
COVID-19 vaccines have saved more than 2 million lives in four years. This record makes them one of humanity’s greatest medical achievements. But what if these vaccines also improved survival for cancer patients? New research suggests that may be possible.
Preclinical results suggest that COVID-19 mRNA vaccines may enhance cancer treatment. Researchers found that these vaccines can improve outcomes for patients receiving a form of immunotherapy. The study linked mRNA COVID-19 vaccines to better survival in cancer patients. These results indicate potential new uses for the vaccine beyond infection prevention.
On October 19, the World Health Organization announced a major milestone. The last Ebola patient in Congo was discharged from treatment. This event marks the start of a 42-day countdown to end the outbreak. The outbreak will be declared over if no new cases appear before the deadline.
The Ebola outbreak began on September 4 in Congo’s Bulape Health District in Kasai. It caused 64 total cases, including 53 confirmed and 11 probable. The WHO reported 43 deaths in the region. Only 19 patients survived, including the final person recently discharged.
It’s hard to imagine millions of people going partially blind unnoticed. However, the sense of smell is much easier to overlook. People can live with a reduced sense of smell and never realize it. This condition can still create serious health and safety risks.
Millions of Americans may have lost their sense of smell unknowingly. COVID-19 can cause a partial or total loss of smell, called hyposmia or anosmia, respectively. Viruses disrupt the cells and receptors in nasal passageways. Sense of smell can recover, but it does not always return.
