WHO: Coronavirus pandemic gatherig pace globally, we see only the tip of the iceberg

Portfolio
A combination of factors, including misinformation that the pandemic is over, the lifting of mask mandates, ending physical distancing - and a more transmissible Omicron BA.2 variant - are causing an increase of COVID-19 cases globally, the World Health Organization warned on Wednesday. Three quarters of new cases over the past 30 days were caused by the new and more transmissible sub-lineage of Omicron. Although BA.2 apparently does not cause more severe illness, the huge number of cases will increase hospitalisations, the WHO warned. Experts are concerned that supply chain disruptions could worsen.

The pandemic is NOT OVER

After several weeks of declines, reported cases of COVID-19 are once again increasing globally, especially in parts of Asia,

WHO Director-General Tedros Adhanom Gebreyesus told journalists in Geneva on Wednesday, the U.N. reported.

In the past week, the agency has seen an 8% increase in detection of COVID-19 cases, with more than 11 million positive test results.

These increases are occurring despite reductions in testing in some countries, which means the cases we are seeing are just the tip of the iceberg,

Tedros explained, warning that when cases tick up, so do deaths.

He added that continued local outbreaks and surges are to be expected, particularly in areas where measures to prevent transmission have been lifted, but that there are ‘unacceptably high’ levels of mortality in many countries, especially where vaccination levels are low among susceptible populations.

“Each country is facing a different situation with different challenges, but the pandemic is not over”, he reiterated.

A combination of factors

WHO’s Dr. Maria Van Kerkhove explained that a combination of factors is fuelling the increase of cases worldwide, beginning with a more transmissible variant.

“We still have Omicron which is transmitting at a very intense level around the world. We have sub-lineages of Omicron BA.1 and BA.2.

BA.2 is more transmissible, and this is the most transmissible variant we have seen of the SARS-COV2 virus to date,

she warned.

The COVID-19 Technical Lead informed that in the last 30 days of more than 400,000 sequences sampled,

99.9% are Omicron, and 75% correspond to the BA.2 variant.

“We do not see an increase in severity with BA.2. However, with huge numbers of cases you will see increase hospitalisations and we have seen this in country after country”, Dr. Van Kerkhove highlighted.

 Another factor influencing the increase of numbers is the lifting of public health and social measures.

Lifting of the use of masks, lifting of physical distancing, lifting of restrictions limiting people’s movement, this provides the virus an opportunity to spread,

Dr. Van Kerkhove cautioned.

Hungary has lifted all pandemic-related restrictions, including mandatory mask-wearing in stores, on 7 March. Meanwhile, there's an influx of refugees from Ukraine currently under siege by Russia, and only about 35% of the population have received two doses of COVID-19 vaccine, and less than 2% had three shots. Up to 15 March, some 430,000 refugees arrived in Hungary from Ukraine.

There are warning signs that the pandemic situation has already started to worsen in Hungary in early March.

How to read the chart?
On the chart above the 0% line is important. When the curves are under 0% there’s a decline, when they go over 0% it’s an increase.

More importantly, when a value is north of 0% but the curve descends, it means an increase at a slowing rate, rather than a decrease. If the curve is above 0% and ascending, it is an increase at an accelerating rate. When we are under 0% and the curve goes lower, it translates into an accelerating decrease, and when it goes up it marks a decelerating decrease.

The expert also pointed out that there are ‘huge amounts of misinformation’ causing a lot of confusion among people.

The misinformation that Omicron is mild, misinformation that the pandemic is over, misinformation that this is the last variant that we will have to deal with,

she explained.

The virus has ‘not settled down’

Meanwhile, Dr Mike Ryan, WHO’s Executive Director of the Health Emergencies Programme clarified that the virus has not ‘settled down’ into a purely seasonal or predictable pattern yet.

“So, the idea that ‘we are through with it’ in the northern hemisphere and now we have to wait until next winter, I think (for example) when we look at increasing rates in the UK,

we need to be very vigilant and cautious with this,

he said.

The expert added that the virus is still ‘very fit’ and it’s moving around easily and in the context of waning immunity and vaccines not acting perfectly against infection, the virus will likely continue to echo around the world.

It will be high in some parts sometimes and then move and be higher again, it will move to another area where immunity is waning.

"The virus will pick up pockets of susceptibility, and we will survive on those pockets for months until another pocket opens.

“This is how viruses work. They establish themselves in a community and they will move quickly to the next community that’s unprotected”, he further explained saying that experts have seen similar patterns with the polio virus.

“We completely understand that the world needs to move on and wants to move on from COVID-19 but this virus spreads very efficiently between people and

if we don’t have the right interventions in place the virus will take opportunities to continue to spread, and the more the virus spreads the more opportunities it has to change,

Dr. Van Kerkhove added.

Vaccination remains key

Both doctors and WHO chief Tedros also spoke about the importance of vaccination pointing out that the majority of deaths remain amongst the unvaccinated, and older individuals and people with underlying conditions who have not received the full course of effective vaccines.

Dr. Van Kerkhove explained that the data shows that COVID-19 vaccines remain ‘incredibly’ effective to prevent severe disease and death, including against Omicron.

She added that the world also needs a very strong surveillance system for COVID-19 to be aware of how the virus is evolving.

“Despite all of the challenges that we are facing, we still need to maintain testing, we still need to maintain robust sequencing and making sure that we have geographic representation of the sequences that are shared”, she underscored.

Supply chain concerns

A coronavirus epidemic of proportions unprecedented for two years is unfolding in China, mainly due to the spread of the Omicron variant, and authorities have already imposed a seven-day city-wide lockdown in the southern Chinese port city Shenzhen, the country's busiest port, also known as "China's Silicon Valley".

The regional container hub, Yantian International Container Terminal announced that it maintained normal operation since the escalation of local Covid-19 prevention and controls and is making great efforts to keep the supply chain running smoothly in Great Bay area, as well as the materials supply supporting Hong Kong.

A Covid outbreak last year in Yantian port that closed around two-thirds of capacity for a three-week period sent shockwaves through the supply chain.

The new restriction measures have hit not only the population, but also large companies that need to react to the latest developments, with manufacturers of everything from flash drives to the glass used in iPhone screens warning of delays in deliveries and announcing temporary factory shutdowns, putting further strain on global supply chains already reeling from the war in Ukraine.
