As the situation of the coronavirus pandemic that hospitals, schools, restaurants, and other places are have been using the technique that can zap viruses and bacteria by the germicidal ultraviolet technology light to cut down on the spread of it. The kind of light that is used, ultraviolet C (UVC), is one of 3 types of rays given off by the sun. It is filtered out by the ozone before it can get to life on Earth. This can kill germs and also cause cancer and destroy our DNA and the corneas of our eyes.
One study found that at least 15 minutes of UVC exposure inactivated SARS, making it impossible for the virus to replicate. Sciences says although there is no concrete evidence for UV's effectiveness on the virus that causes COVID-19. So, it has worked on other similar viruses. There are several portable UV sanitizing devices that whole manufacturers claimed that can kill 99.9% of bacteria and viruses on phones, pacifiers, and other surfaces that can get contaminated. But safety concerns remain, and some researchers have already started examining ways to harness the destructive properties of UV light while suppressing the danger of using it.
People all around the world want to know the same thing about some people who had been vaccinated or recovered from the disease will get the result that they were infected to the COVID-19 again or not. However, in the current study, many of the repeat positives happened a month after the first infection as far out as 48 weeks. The study has found that people who recovered from SARS maintained antibodies to it for an average of 2 years. Some public policy the governments have proposed giving "immunity passports" to people who have been vaccinated for antibodies to SARS - CoV-2 are allowing them to return to work or to travel, under the assumption they won't get infected. But the World Health Organization (WHO) has cautioned against it that the evidence having antibodies to the new types of coronavirus would be not guaranteed protection from reinfection again.
As Delta virus which upgrades from the variant coronavirus in July may be fueling a rise of breakthrough COVID-19 infections among fully vaccinated people. By this disease at least 1 of 5 new COVID-19 cases have involved vaccinated people with higher percentages of hospitalizations and deaths. The increase of the vaccinated people will show up more frequently than before in severely will and dead.
The U.S. recommended booster shots for most people within 8 months after they received their second dose of either Pfizer or Moderna COVID-19 vaccines, as the high infections Delta variant marches across the world. The officials could announce the decision as early as this week, with third shots would becoming available to those most vulnerable as early. The people who choose the single dose of the Johnson & Johnson vaccine will also need a booster shot.
