Can mosquitoes spread the coronavirus?

  • No. While mosquitoes can spread some diseases, most notably malaria, experts say COVID-19 is not among them
  • Researchers say the virus would have to infect the mosquito and multiply inside of it in order for the mosquito to pass it on to people

Covid-19: A cheaper, faster, accurate testing for coronavirus developed

  • The method simplifies and frees the testing from expensive reaction steps, enabling upscaling of the diagnostics
  • This makes the method particularly attractive for places and situations with limited resources

The COVID-19 test kit is far more economical and reliable than the ones used currently, claimed the makers (AFP)

SinoVac's CEO says they have injected 90 percent of its employees and family members, or about 3,000 people, and provided tens of thousands of rounds of CoronaVac to the municipal government of Beijing. It's a highly unusual move that raises ethical and safety questions, as companies and governments worldwide race to develop a vaccine that will stop the spread of the new coronavirus.

Pfizer urged to wait for November to seek covid vaccine approval

  • Researchers said Pfizer’s clinical trial needs to monitor participants for at least two months after they received the second dose
  • Pfizer signed a pledge earlier this month not to cut corners on a vaccine

Talc, petroleum jelly among best lubricants for people wearing PPE: Study

  • The scientists added that many typical moisturisers do not last long as they are designed to be absorbed into the skin for a 'non-greasy feel'
  • According to study, the best lubricants to use are those that don't absorb into the skin, creating a long-lasting layer of protection between skin and PPE

The British government on Thursday, Sept. 24, 2020 says it may take part in a study that tries to deliberately infect volunteers who have been given an experimental vaccine against the coronavirus in an effort to more quickly determine if the vaccine works. The approach, called a challenge study, is risky but proponents think it may produce results faster than typical studies, which wait to see if volunteers who have been given an experimental treatment or a dummy version get sick.

Coronavirus infected two pairs of brothers. The link may lead to new treatment

  • Interferon’s role represents a new nexus in Covid-19’s complex interaction with the human immune system
  • Many patients suffer their worst complications because of an immune overreaction sometimes called a cytokine storm, and may benefit from dexamethasone, a cheap generic that calms these storms
