    The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.

    Omicron infections no less severe based on early UK data

    Infections caused by the Omicron variant of the coronavirus do not appear to be less severe than infections from Delta, according to early data from the UK.

    Researchers at Imperial College London compared 11,329 people with confirmed or likely Omicron infections with nearly 200,000 people infected with other variants. So far, according to a report issued ahead of peer review and updated on Monday, they see "no evidence of Omicron having lower severity than Delta, judged by either the proportion of people testing positive who report symptoms, or by the proportion of cases seeking hospital care after infection."

    For vaccines available in the UK, effectiveness against symptomatic Omicron infection ranged from 0% to 20% after two doses, and from 55% to 80% following a booster dose. The report also estimated that after taking individual risk factors into account, the odds of reinfection with Omicron are 5.4 times greater than for reinfection with Delta. A study of healthcare workers in the pre-Omicron era estimated that a prior SARS-CoV-2 infection afforded 85% protection against a second infection over 6 months, the researchers said, while "the protection against reinfection by Omicron afforded by past infection may be as low as 19%."

    Sperm count, motility may be low for months after COVID-19

    Sperm quality is impaired for months for some people after recovery from COVID-19, researchers have found.

    The semen itself was not infectious, the researchers found. But among 35 men who provided samples within a month after recovery from symptomatic infection, reductions in sperm motility were evident in 60% and sperm counts were reduced in 37%. As reported on Monday in Fertility and Sterility, semen samples were obtained from 120 Belgian men with an average age of 35 years, at an average of 52 days after their COVID-19 symptoms had resolved. Among 51 men tested between one and two months after recovery, 37% had reduced sperm motility and 29% had low sperm counts. Among 34 men who provided semen samples at least two months after recovery, sperm motility was impaired in 28% and sperm counts were low in 6%. The severity of COVID-19 infection was not correlated with sperm characteristics.

    "Couples with a desire for pregnancy should be warned that sperm quality after COVID-19 infection can be suboptimal," the researchers concluded. "The estimated recovery time is 3 months, but further follow-up studies are under way to confirm this and to determine if permanent damage occurred in a minority of men."

    Neutralizing molecule could be cheaper than antibodies

    An experimental molecule that neutralizes the coronavirus in the same way antibodies do would be cheaper and easier to manufacture, researchers said.

    The sperm quality issue was known since the beginning of Covid. Many were worried about the vaccines causing infertility, ignorant of what the diseaase has in stock. :(
    This was the same with SARS-Cov-1 and several other viruses (eg Ebola, Zika, herpes simplex, Epstein-Barr, HPV, HIV and mumps) have been known to cause temporary or permanent fertility issues.
    Very early Chinese studies with Covid showed that nearly 35% had suboptimal sperms at least temporarily. The results indicated that ACE2 highly expresses in renal tubular cells, Sertoli cells, Leydig cells, and cells in seminiferous ducts in testis.

    COVID-19 වලින් සුවය ලැබීමෙන් පසු සමහර පුද්ගලයින්ට මාස ගණනාවක් ශුක්‍රාණු වල ගුණාත්මක භාවය අඩාල වන බව පර්යේෂකයන් සොයාගෙන ඇත.
    සුවය ලැබීමෙන් පසු මාස එකත් දෙකත් අතර පරීක්‍ෂාවට ලක් කළ පිරිමින් 51 දෙනාගෙන් 37%ක් ශුක්‍රාණු චලනය අඩු වී ඇති අතර 29%කගේ ශුක්‍රාණු ගණන අඩු වී ඇත.
    COVID-19 ආසාදනයෙන් පසු ශුක්‍රාණු වල ගුණාත්මක භාවය උපප්‍රශස්ත විය හැකි බවට ගැබ් ගැනීමට ආශාවක් ඇති ජෝඩුවලට අනතුරු ඇඟවිය යුතුය.

    Dammit. I was relaxed; thinking Omicron is less severe; hence no need to be worried. Guess I was wrong.
    At 24 hours after infection, the Omicron variant replicated around 70 times higher than the Delta variant and the original SARS-CoV-2 virus. In contrast, the Omicron variant replicated less efficiently (more than 10 times lower) in the human lung tissue than the original SARS-CoV-2 virus, which may suggest lower severity of disease.

    Does that mean you won't die of pneumonia even if you got infected by Omricon?
    See... there is a silver line in this dark cloud as well.. isn't it? ;) :lol:

    It appears to be so but no one confirms it. Scientists are unsure whether it's the variant behaviour or whether it's due to our immune system fighting better (with vaccine immunity & infection induced immunity)
    South African Health reports- Only 1.7% of identified Covid-19 cases were admitted to hospital in the second week of infections in the fourth wave, compared with 19% in the same week of the third delta-driven wave. So it seems that the hospitalization rates is low. (y)
