Mexico sheds light on molnupiravir for coronavirus patients

Mexico has approved the emergency use of Merck’s molnupiravir antiviral drug to treat Covid-19 patients, state health regulator COFEPRIS said in a statement.

COFEPRIS was expected to soon approve Pfizer’s Paxlovid pill to treat Covid-19, Lopez Obrador added at a regular press conference. Both drugs were approved in the United States last month.

Molnupiravir was developed at Ridgeback Biotherapeutics and has been shown in clinical trials in high-risk individuals in the early stages of illness to reduce hospitalization and mortality by approximately 30%.

Rapid Covid tests may not give good results-studies

According to infectious disease experts, wiping the nose with a rapid antigen test does not reliably detect Omicron variants in the first few days of infection, allowing manufacturers to safely collect samples from the throat as well. You need to seek US approval for this.

The US Food and Drug Administration has expressed concern about the safety of self-pharyngeal swabs.

Infected in the throat and saliva, but before the virus reaches the nose, people can already infect others with Omicron, so wiping the nostrils in the early stages of infection will not pick it up, Former Harvard TH Dr. Michael Mina Chan School of Public Health and now eMed’s Chief Science Officer said at a press conference.

A study published at medRxiv prior to peer review examined 29 Omicron-infected workers in high-risk occupations who underwent PCR and antigen testing simultaneously for multiple days. PCR tests on saliva detected the virus an average of 3 days before a rapid nasal swab sample became positive.
