Delta variant, a warning the COVID-19 virus is getting ‘fitter and faster’

Published

on

Cases and deaths resulting from COVID-19 continue to climb worldwide, mostly fuelled by the highly transmissible Delta variant, which has spread to 132 countries, said the head of the World Health Organization (WHO) on Friday.

Almost 4 million cases worldwide were reported last week to WHO and the agency expects the total number of cases to pass 200 million, in the next two weeks.

“And we know this is an underestimate”, underscored Director-General Tedros Adhanom Gebreyesus during his regular COVID-19 briefing.

Infections have increased in every region of the world, with some even reaching 80 per cent more in the past month. In Africa, deaths have increased by 80 per cent over the same period, the official warned.

Overwhelmed

Tedros blamed the rise of cases on increased social mixing and mobility, the inconsistent use of public health and social measures, and inequitable vaccine use. He said “hard-won gains” are in jeopardy or being lost, and health systems in many countries are increasingly overwhelmed.

“WHO has warned that the COVID-19 virus has been changing since it was first reported, and it continues to change. So far, four variants of concern have emerged, and there will be more as long as the virus continues to spread”, he underscored.

A higher viral load

Lead WHO epidemiologist and COVID-19 technical lead, Dr. Maria Van Kerkhove, explained that the Delta variant has certain mutations that allow the virus to adhere to human cells more easily and that experts are also seeing a higher viral load in individuals infected.

She called Delta “dangerous and the most transmissible SARS-CoV-2 virus to date”. 

“There are some laboratory studies that suggest that there’s increase replication in some of the modelled human airway systems”, she added.

In terms of severity, Dr. Van Kerkhove highlighted that there has been an increase in hospitalizations in certain countries affected by the variant, “but we haven’t yet seen an increase in mortality”.

The WHO expert reminded that although there is some data that suggest that people vaccinated can get infected and transmit the variant, the likelihood is much reduced after the second dose has been administered and reached full effectiveness.

She also clarified that Delta is not specifically targeting children as some reports have suggested, but warned that as long as the variants are circulating, they will infect anybody that is not taking proper precautions.

Continuing to evolve

“It’s in the virus’s interests to evolve, viruses are not alive they don’t have a brain to think through this, but they become more fit the more they circulate, so the virus will likely become even more transmissible because this is what viruses do, they evolve they change overtime”, Dr. Van Kerkhove warned, echoing Tedros’ remarks.

We have to do what we can to drive it down”, she added, reminding that public health and social measures do work against the Delta variant, and that the vaccines do prevent disease and death.

Dr. Michael Ryan, Executive Director of WHO Health Emergencies, said that even with the virus getting “faster and fitter” the gameplan does not change, but It needs to be implemented more efficiently.

“Delta is a warning that this virus is evolving, but it is also a call to action before more dangerous variants emerge”, he said.

Shots for Africa

Last month, the WHO chief announced the setting up of a technology transfer hub for mRNA vaccines In South Africa as part of WHO’s efforts to scale up production of vaccines and their distribution in Africa.

“Today we have taken another step forward, with a letter of intent that sets out the terms of collaboration signed by the partners in the hub: WHO; the Medicines Patent Pool; Afrigen Biologics; the Biologicals and Vaccines Institute of Southern Africa; the South African Medical Research Council and the Africa Centres for Disease Control and Prevention”, Tedros explained.

He added that WHO’s goal remains to aid every country in vaccinating at least 10% of its population by the end of September, at least 40% by the end of this year, and 70% by the middle of next year.

“We are a long way off achieving those targets. So far, just over half of countries have fully vaccinated 10% of their population, less than a quarter of countries have vaccinated 40%, and only 3 countries have vaccinated 70%”, Tedros warned.

The WHO head reminded that the global distribution of vaccines remains unjust, despite expert warnings and appeals, and said that all regions remain at risk, “none more so, than Africa”.

“On current trends, nearly 70% of African countries will not reach the 10% vaccination target by the end of September”, he cautioned.

New tool to fight Delta

Tedros also announced that on response to the Delta surge, the WHO’s Access to COVID-19 Tools Accelerator is launching the Rapid ACT-Accelerator Delta Response, or RADAR, and issuing an urgent call for 7.7 billion U.S. dollars for tests, treatments and vaccines.

COVID-19: WHO expresses hope worst of Omicron wave is over

Published

on

Omicron continues to sweep the world, but cases seem to have peaked in some countries, which gives the head of the World Health Organization (WHO) hope that the worst of this latest wave of COVID-19 is over. 

Briefing journalists in Geneva, Tedros Ghebreyesus said that more than 18 million cases were reported last week, and the pandemic itself is far from over, so no country is out of the woods yet.

The number of deaths remains stable, but the agency is concerned about the impact the variant is having on already exhausted health workers and overburdened health systems.

“I remain particularly concerned about many countries that have low vaccination rates, as people are many times more at risk of severe illness and death if they’re unvaccinated”, Tedros said. 

Omicron may be less severe, but for the WHO chief “the narrative that it is mild disease is misleading, hurts the overall response and costs more lives.”

Tedros noted that the virus is circulating “far too intensely with many still vulnerable” and argued that, for many countries, the next few weeks remain critical.

COVAX

Over the weekend, the UN-backed COVAX facility delivered its one-billionth dose of vaccine. 

Tedros said he was proud of the milestone, but believes it’s essential to keep forging ahead with distributing shots fairly, across the world. 

“Vaccines may be less effective at preventing infection and transmission of Omicron than they were for previous variants, but they still are exceptionally good at preventing serious disease and death”, he explained. 

For him, immunization continues to be “key to protecting hospitals from becoming overwhelmed.”

Tracking the virus

The WHO chief also highlighted the importance of tracking new variants, like Omicron, in real time.

Tedros believes that the pandemic is “nowhere near over” and, with the incredible growth of Omicron, new variants are likely to emerge

So far, more than 7 million whole genome sequences from 180 countries have been submitted to GISAID, a global mechanism that provides open access to genomic data and was initially set up to track flu.

Using all that data, new formulations of vaccines are being developed and assessed for how they perform against different strains. 

Despite those efforts, Tedros is concerned that the world will enter “a second and even more destructive phase of vaccine inequity”, if it doesn’t change course. 

New treatments 

Last Friday, WHO recommended two new COVID-19 treatmentsto fight severe illness and death: a rheumatoid arthritis drug called baricitinib and a monoclonal antibody called sotrovimab.

For Tedros, the challenge, once again, is that high prices and limited supply means access is limited.

WHO is currently working with its partners in ACT-Accelerator to negotiate lower prices with manufacturers and ensure supply will be available for low- and middle-income countries.

Meeting

Next week, the WHO Executive Board, which is made up of 34 Member States, will meet to discuss the world’s health challenges.

The pandemic will remain at the forefront, but Member States will also be discussing the devastating impact of the pandemic on other health issues, and how the backsliding can be stopped. 

According to the WHO chief, the agency willbe working to accelerate progress on negotiations around a global pandemic accord.

Cervical Cancer Awareness

On a final note, Tedros noted that January is Cervical Cancer Awareness month.

In 2020, an estimated 604,000 women were diagnosed with cervical cancer worldwide and about 342, 000 women died from the disease.

The main cause of the disease is infection with high-risk types of human papillomavirus (HPV), an extremely common family of viruses that are transmitted through sexual contact.

There are, however, vaccines that protect against high-risk HPV types, which means it should be one of the most preventable and treatable forms of cancer.

On Monday, Serbia announced that this year,it will introduce a vaccination programme against HPV, joining the 116 nationswho already do it.

UN-backed COVAX mechanism delivers its 1 billionth COVID-19 vaccine dose

Published

With a 1.1 million jab delivery in Rwanda this weekend, the World Health Organization’s multilateral initiative to provide equal access to vaccines for all reached the one billion milestone.

Along with the Coalition for Epidemic Preparedness Innovations (CEPI), the Vaccine Alliance GAVI, and partners, WHO has led the largest vaccine procurement and supply operation in history with deliveries to 144 countries to date.

According to a press release published on Sunday, as of 13 January 2022, out of 194 countries members of WHO, 36 have vaccinated less than 10% of their population, and 88 less than 40%.

COVAX’s ambition was compromised by hoarding/stockpiling in rich countries, catastrophic outbreaks leading to borders and supply being locked. And a lack of sharing of licenses, technology, and know-how by pharmaceutical companies meant manufacturing capacity went unused”, the agency explained.

On 24 February 2021, Ghana became the first country in the world to receive vaccines through COVAX when 600,000 doses of the Oxford–AstraZeneca vaccine were delivered to Accra. 

The work that remains

COVAX is currently working with governments, manufacturers and partners to ensure that when countries receive vaccines, they can get them to people quickly.

“The work that has gone into this (1 billion) milestone is only a reminder of the work that remains”, the UN’s health agency underscored.

They added that with updated vaccines in the pipeline, citizens should demand that governments and pharmaceutical companies share health tools globally and “bring an end to the death and destruction cycles of this pandemic, limit new variants and drive a global economic recovery”.

COVAX is one of three pillars of the Access to COVID-19 Tools (ACT) Accelerator, which was launched by WHO in April 2020 in response to the pandemic.

The ACT Accelerator is a ground-breaking global collaboration to accelerate the development, production, and equitable access to COVID-19 tests, treatments, and vaccines.

WHO recommends two new drugs to treat patients with COVID-19

The World Health Organization (WHO) on Thursday reccommended two new drugs to treat patients with COVID-19, one for patients with critical disease, and another deemed effective for non-severe cases.

The first drug, baricitinib, is a Janus kinase (JAK) inhibitor- a class of drugs used to treat autoimmune conditions, blood and bone marrow cancers, and rheumatoid arthritis.

According to the WHO Guideline Development Group, it is “strongly recommended” for patients with severe or critical disease in combination with corticosteroids.

The group of international experts based their recommendation on “moderate certainty evidence” that it improves survival and reduces the need for ventilation.

There was no observed increase in adverse effects.

The experts note that it has a similar effectas other arthritis drugs called interleukin-6 (IL-6) inhibitors. Because of that, when both drugs are available, they suggest choosing the best option based on cost, availability, and clinician experience.

It is not recommended to use both drugs at the same time.

The experts also advise against the use of two other JAK inhibitors (ruxolitinib and tofacitinib) for patients with severe or critical cases of COVID-19 infection.

According to them, trials undergone using these drugs failed to show any benefits arising using either drug,and suggested a possible increase in serious side effects with tofacitinib.

Non-severe cases

In the same update, WHO makes a conditional recommendation for the use of a monoclonal antibody known as sotrovimab in patients with non-severe cases.

According to them, the drug should only be administered to patients at the highest risk of hospitalisation. In those at lower risk, it onlyshowed “trivial benefits”. 

A similar recommendation has been madepreviously, for another monoclonal antibody drug, casirivimab-imdevimab, and the experts say there is insufficient data to recommend one over the other.

For both, the effectiveness against new variants, like Omicron, is still uncertain. 

The group will update their guidelines for monoclonal antibodies when more data becomes available.

Recommendations

These recommendations are based on new evidence from seven trials involving over 4,000 patients with non-severe, severe, and critical infections.

Developed by WHO with the methodological support of MAGIC Evidence Ecosystem Foundation, the guidelinesprovide trustworthy guidance and help doctors make better decisions with their patients.

According to the agency, the guidelines are useful in fast moving research areas, because they allow researchers to update evidence summaries as new information becomes available.

The latest guidance also updates recommendations for the use of interleukin-6 receptor blockers and systemic corticosteroids for patients with severe or critical COVID-19; conditional recommendations for the use of casirivimab-imdevimab (another monoclonal antibody treatment) in selected patients; and against the use of convalescent plasma, ivermectin and hydroxychloroquine, regardless of disease severity.
