Updates in brief published in

  • Researchers have found that death rate from Covid-19 is surprisingly higher in Black, Native American and Latino communities than other groups.
  • The causes of above difference are medical conditions, unequal approach to healthcare services and jobs demanding to work closely with the public.
  • Experts pointed out that Covid-19 pandemic has urged to improve medical services, housing and job opportunities for colour communities.
  • It is also revealed that  older black American are  at higher risk of dying from Covid-19 than most of the population.
  • One factor is that older Black American usually have sever medical condition.
  • The second factor : Many old Black American live in multigenerational homes where coronavirus can spread easily.
  • In addition, the elder Black American may be more reluctant to get tested or seek treatment , because of mistrust of healthcare performance.
  • A Nordic study involving Finland, Sweden , Norway and Denmark found that men under the age of 30, who received Modena Spikevax , had a slightly higher risk than others developing “Myocarditis “, said Mika Salminen, PhD, Director of the Finnish Health Institute , told Reuters.
  • Some women may experience temporary changes in menstrual volume and menstrual cycle length due to Vovid-19 .
  • The most commonly observed changes were lighter than normal period. An increased menstrual cycle length was also observed.
  • Sex hormones levels has no significantly changes with Covid-19 and those without Covid-19.
  • “Outbreak info.” a website that tracks the coronavirus and its variants globally, revealed in their data, there have been no case of Mu variant detected in the U.S. in the past 7 days.
  • People who recovered from Covid-19 have a higher risk of stroke, heart attack and other cardiovascular problems even months late.
  • Heart disease is currently leading cause death in the U.S.
  • More than 44 million American and 237 million people world wide have  survived from Covid-19.


Updates in brief, published in ””.

  • Researchers are hopeful that people who have had Covid-19 and later received the first dose of  mRNA vaccine, will develop exceptional immunity against a wide range of variants of the virus.
  • These individual could have some protection against similar virus that may jump from animals to humans to cause further pandemics .
  • People who recovered from Covid-19, and later have a first dose of vaccine have stronger immunity than they would otherwise. This is because their immunity system recognizes all 25 proteins that make up a SARS-2 virus.
  • It was very little flu activity last year, experts think, the  2021-2022 flu season may be more difficult.
  • A new study has found that a drug combination involving the antiviral interfaces -alpha  and nafamostat effectively combatted SARS-2 infection. The drug combination inhibited SARS-2 replication in cell culture . In animal study it showed a lower concentration than the individual drug.
  • A study conducted by the University of Toronto ( Canada) and appeared in the ” Canadian Medical Association Journal ( CMAJ) shows that :
  • New variants of SARS-2 are more violent and transmissible than the original variant of the virus.
  • Health experts associated these variants of  concern  (vocs) , with increased risk hospitalization , intensive care unit (icu)admission and death.
  • Vaccination reduces the risk of severe diseases and death even with vocs.
  • Scientists have identified a genetic link between development of Alzheimer and severe Covid-19 outcome.
  • Scientists also identified that  the same immune system changes in both diseases.
  • Experts have detected the R-1 variant of SARS-2Cov-2 around the world since late 2020.
  • The variant shares some mutations with other variants that are more infectious.
  • However, scientists say that  R-1 variant is not of concern and that the Delta variant is still dominant in many countries.
