SINGAPORE (Reuters) - A company in Singapore has developed a breathalyser test for the new coronavirus which it says will enable people to know whether they are infected in under a minute.
For the second time, a study testing an experimental antibody drug for COVID-19 has been paused to investigate a possible safety issue in hospitalized patients.
There’s encouraging news about antibodies in a new paper published in the journal Science from researchers at New York City’s Mount Sinai Hospital. In their study of the antibody responses of patients with either mild or moderate Covid-19, antibody levels appeared to stay relatively stable for at least five months, and their presence was correlated with the inactivation of the virus.
Antibodies are molecules pumped out by the immune system in response to infection, and they have a role in preventing future infections, though exactly how they function within the context of Covid-19 isn’t clear yet. Scientists are urgently trying to figure out whether the presence of antibodies actually means a person is protected from future infection as well as how long antibodies last in the body. Knowing this is crucial, especially for vaccine development.
(Reuters) - Global coronavirus cases rose by more than 500,000 for the first time on Wednesday, a record one-day increase as countries across the Northern Hemisphere reported daily spikes.
