Is the COVID-19 pandemic over? WHO to vote whether to end global health emergency declaration

WASHINGTON - It’s almost hard to believe that nearly three years have passed since the World Health Organization declared the outbreak of a virus — later named SARS-CoV-2 — as a public health emergency of international concern (PHEIC). But on Friday, a committee is meeting to deliberate and vote whether it is time to recommend to WHO Director-General Tedros Adhanom Ghebreyesus that he declare the global health emergency is over. The committee advises the director-general, who will make the final decision, but he generally follows the committee’s advice.Days before the vote, the director-general said in a media briefing that he was "very concerned" about the rising number of COVID-19 deaths globally.

(Photo by Fabrice COFFRINI / AFP) (Photo by FABRICE COFFRINI/AFP via Getty Images) "While I will not pre-empt the advice of the Emergency Committee, I remain very concerned by the situation in many countries and the rising number of deaths," Tedros said Tuesday, suggesting the committee may not think it’s the right time to advise Tedros to terminate the declaration. Worldwide, deaths have steadily increased since December, according to recent data by Johns Hopkins University.

Why is it difficult to trace COVID virus ancestor? Experts explain

Coronaviruses recombine fast and much time has passed since the time it might have originated It is common knowledge that SARS-CoV-2 that causes COVID-19 jumped from bats but what still remains a mystery is the origin of the virus and how it jumped to humans. A new study has revealed that chances of finding the direct ancestor of the SARS-CoV-2 virus are very bleak. It also states that COVID virus probably shared an ancestor with the coronaviruses found in bats more recently than was thought.

The researchers have said in the study that some mouthwashes, that contain a chemical known as ‘cetylpyridinium chloride (CPC)’ block the entry of the SARS-CoV-2 virus into the cells, thus, suppressing the infection. The researchers have said that commercially available mouthwashes contain a number of antibiotic and antiviral components that act against microorganisms in the mouth.

ANI says that infection with SARS-COV-2 can cause brain alterations and neurocognitive dysfunction, particularly in long Covid-19, but the underlying mechanisms are elusive. Daniel Martins-de-Souza and colleagues conducted MRI of 81 study participants recovering from mild Covid-19 infection and 81 healthy individuals to compare their brain structure. It was found that the former group exhibited reduced cortical thickness, which was correlated with cognitive impairments and symptoms such as anxiety and depression.
