Medication Good News For COVID-19 Interferon Alpha 2B and Favipiravir shows good clinical efficacy in treating COVID-19

For 40 years, Cuba has been using a molecule named Interferon Alpha 2B, which has successfully been used to combat the new Coronavirus in China and elsewhere.

"The world has an opportunity to understand that health is not a commercial asset but a basic right," Cuban doctor Luis Herrera, the creator of the Interferon Alfa 2-B medication, one of the most successful medications in the fight against COVID-19
One of the ways the virus can multiply inside the cells is by decreasing the levels of Interferon naturally produced in human cells. The molecule thus, through a different metabolic way, it is able to create conditions in order to limit the replication of the virus.
Interferons (IFNs) comprise a family of secretory proteins induced in response to specific extracellular stimuli through stimulation of toll-like receptors (TLRs; ). Acting in paracrine or autocrine modes, IFNs stimulate intra- and intercellular networks for regulating innate and acquired immunity, resistance to viral infections, and normal and tumour cell survival and death. Through high-affinity cell surface receptors IFNs stimulate genes, using signalling molecules used by other cytokines, but first identified through studies of IFNs. Perturbations in these pathways can lead to overstimulation of cellular functions or can make cells resistant to a given ligand, facilitating either progression or resistance of malignancy. IFNs act on almost every cell type and through their cellular actions can be effective in inhibition of tumour emergence, progression, and for inducing regression



Favipiravir

Favipiravir (T-705; 6-fluoro-3-hydroxy-2-pyrazinecarboxamid,) is an antiviral drug that selectively inhibited the RdRP of influenza virus. It showed specific activity against all three influenza A, B, and C. also inhibited the RV replication in HeLa cells, with an EC50 of 29 µg/mL.  
The analysis showed that the primary mechanism of action of favipiravir against the influenza virus was a specific inhibition of vRNA polymerase. It is predicted that a similar mechanism might occur with other viruses, such as PV and RV, inhibited by favipiravir, which may account for its broad-spectrum inhibition. Mechanistic studies show that the favipiravir and its form favipiravir-RMP (favipiravir-ribofuranosyl-50-monophosphate) do not inhibit influenza RNA polymerase activity, but it is the phosphoribosylated form, favipiravir-ribofuranosyl-50-triphosphate (RTP) that inhibits the enzyme. Metabolism of favipiravir to its triphosphate form occurs in an extracellular environment in a concentration-dependent manner. The vRNA polymerase mistakenly recognizes favipiravir-RTP as a purine nucleotide. This favipiravir-RTP is misincorporated in nascent vRNA, or it may act by binding to conserved polymerase domains, preventing incorporation of nucleotides for vRNA replication and transcription.


China has completed the clinical research of Favipiravir, an antiviral drug that has shown good clinical efficacy against the novel coronavirus disease (COVID-19), according to an official Tuesday.

Favipiravir, the influenza drug which was approved for clinical use in Japan in 2014, has shown no obvious adverse reactions in the clinical trial, said Zhang Xinmin, director of the China National Center for Biotechnology Development under the Ministry of Science and Technology, at a press conference.

More than 80 patients have participated in the clinical trial in The Third People's Hospital of Shenzhen, south China's Guangdong Province, including 35 patients taking Favipiravir and 45 patients on a control group. Results showed that patients receiving Favipiravir treatment turned negative for the virus in a shorter time compared with patients in the control group.

 a multi-centred randomized clinical study led by the Zhongnan Hospital of Wuhan University also suggested that the therapeutic effect of Favipiravir is much better than that of the control group.

Favipiravir has been recommended to medical treatment teams and should be included in the diagnosis and treatment plan for COVID-19 as soon as possible, Zhang said.

Scientists at the Kaiser Permanente Washington Research Institute in Seattle delivered the first rounds of a potential coronavirus a vaccine to several dozen optimistic volunteers earlier this week.

One 43-year-old vaccine recipient is Jennifer Haller, who is a mother to two teenagers.

She was all smiles afterwards, telling AP reporters she was “feeling great” as she was leaving the clinic.

“This is an amazing opportunity for me to do something,” she added.

2) Distilleries Across the United States Are Making Their Own Hand Sanitizers to Give Away for Free
Amidst national shortages of hand sanitizers, alcohol distilleries in Atlanta, Portland, rural Georgia, and North Carolina have begun using their facilities to make their own sanitation products. 
Since the World Health Organization (WHO) says that cleaning your hands with an alcohol-based rub can help to kill viruses on your hands, many of the distilleries say they hope to continue producing their bootleg sanitizers until the virus has been properly contained.

3) Air Pollution Plummets in Cities With High Rates of Quarantine
Satellite readings of air pollution levels over China and Italy show that the regions hit hardest by the COVID-19 have also caused air pollution levels to decline dramatically.


Some reports estimate that China’s quarantine has saved more than 100 million metric tons of carbon dioxide emissions from entering the atmosphere—which is about the equivalent of what Chile produces in a year.

Not only have similar effects been reported across Italy, the canals and waterways of Venice are reportedly cleaner than ever with the waters shining crystal clear in the absence of diesel-powered boats and gondoliers.

4) Johns Hopkins Researcher Says That Antibodies From Recovered COVID Patients Could Help Protect People At Risk
The vaccine being tested in Seattle isn’t the only potential treatment for the disease—an immunologist from Johns Hopkins University is reviving a century-old blood-derived treatment for use in the United States in hopes of slowing the spread of the disease.

The technique uses antibodies from the blood plasma or serum of people who have recovered from COVID-19 infection to boost the immunity of newly-infected patients and those at risk of contracting the disease.

5) South Korean Outbreak Finally Abating as Recoveries Outnumber New Infections for Three Days in a Row

According to Reuters, South Korea recorded more COVID-19 recovery cases on March 6th than new infections for the first time since the nation experienced the largest Asian outbreak outside of China.

Since the novel coronavirus outbreak was first reported in South Korea back in January, the nation reached a peak of 909 new infections on February 29th. Now, however, Reuters reports that the declining rate of infection has continued to fall with less than 100 new cases reported for several days in a row.

6) China Celebrates Several Milestones of Recovery After Temporary Hospitals Close and Parks Reopen
Crowds of medical staffers and discharged patients were filmed celebrating the closure of all 14 temporary hospitals that opened in Wuhan to treat COVID-19 patients during the worst of the outbreak.

Authorities told the South China Morning Post this week that the virus had finally passed its peak as the nation’s mainland experienced only 11 new cases on March 13th, most of which were from international travellers.

As the outbreak is finally brought under control, parks and tourist attractions are slowly beginning to reopen to the public under careful moderation.

7) Australian Researchers Testing Two Drugs as Potential ‘Cures’ for the Virus

Professor David Paterson, director of the University of Queensland Centre for Clinical Research and infectious disease physician at the RBWH.
At the University of Queensland Centre for Clinical Research, scientists have found that two different medications—both of which are registered and available in Australia—have completely wiped out traces of the disease in test tubes.

Not only that, but the drugs were also given to some of the nation’s first COVID-19 patients, which resulted in “disappearance of the virus and complete recovery from the infection,” researchers told 
The university is now looking to conduct a nationwide trial with the drugs to evaluate the efficacy and tolerance of each drug administered separately and together.
