COVID-19 could become a 'seasonal menace' in the future says UN task team

The team insisted that weather and climate conditions alone should for now not be the trigger for loosening anti-Covid restrictions.

COVID-19 appears likely to develop into a seasonal disease, the United Nations said Thursday, cautioning though against relaxing pandemic-related measures simply based on meteorological factors. More than a year after the novel coronavirus first surfaced in China, a number of mysteries still surround the spread of the disease that has killed nearly 2.7 million people worldwide. In its first report, an expert team tasked with trying to shed light on one of those mysteries by examining potential meteorological and air quality influences on the spread of COVID-19 , found some indications the disease would develop into a seasonal menace.

The 16-member team set up by the UN's World Meteorological Organization pointed out that respiratory viral infections are often seasonal, "in particular the autumn-winter peak for influenza and cold-causing coronavirus es in temperate climates."

"This has fuelled expectations that, if it persists for many years, COVID-19 will prove to be a strongly seasonal disease," it said in a statement.

Modelling studies anticipate that transmission of SARS-CoV-2, the virus that causes COVID-19 disease, "may become seasonal over time".

Trigger?

But COVID-19 transmission dynamics so far appear to have been influenced mainly by government interventions like mask mandates and travel restrictions, they said, rather than the weather.

The task team, therefore, insisted that weather and climate conditions alone should for now not be the trigger for loosening anti-Covid restrictions.

"At this stage, evidence does not support the use of meteorological and air quality factors as a basis for governments to relax their interventions aimed at reducing transmission," said task team co-chair Ben Zaitchik of the earth and planetary sciences department at The John Hopkins University in the United States.

He pointed out that during the first year of the pandemic, infections in some places rose in warm seasons, "and there is no evidence that this couldn't happen again in the coming year".

The experts, who focused only on outdoor meteorology and air quality conditions in the report, said laboratory studies had provided some evidence the virus survives longer in cold, dry weather and when there is low ultraviolet radiation.

But it remained unclear whether meteorological influences "have a meaningful influence on transmission rates under real world conditions".

They also highlighted that evidence around the impact of air quality on the virus remained "inconclusive".

There was some preliminary evidence that poor air quality increases COVID-19 mortality rates, "but not that pollution directly impacts airborne transmission of SARS-CoV-2".

“Annual revaccination increasingly likely,” says Pfizer: Why a post-pandemic world may call for booster shots

The reality that vaccinations could become seasonal or annual owing to the limited protection they may come to offer is one that experts are now largely coming to terms with. 

KEY HIGHLIGHTS

• There is already some evidence that providing smaller doses in several shots may be more effective than larger doses in fewer shots

• Booster shots effectively capitalise on what's known as “immunological memory” where our cells remember the previous vaccine we may have received, and work faster and more aggressively to build up antibody responses to further shots

• Like the influenza virus, SARS-CoV-2 has also mutated several times and scientists are still scrambling to understand how these changes affect virus efficacy

 

Global pharmaceutical giant, Pfizer made headlines last month when it announced that it would seek to increase the prices of its COVID-19 vaccine after the world emerged from the throngs of the pandemic. 

And at an investor conference hosted by Barclays recently, the company's Chief Financial Officer, Frank D'Amelio reiterated the company's stance, noting that the manufacturer saw “significant opportunity” for its vaccine when the market moved from the current “pandemic situation to an endemic situation.” Crucially, D'Amelio also confirmed that Pfizer believed that annual vaccinations were now “increasingly likely.”

Given the fact that the virus continues to spread across the world, and thereby continued to mutate into varied strains, some of which have already proven to be more aggressive and lethal than others, the reality that vaccinations could become seasonal or annual owing to the limited protection they may come to offer is one that experts are now largely coming to terms with. 

What this may ultimately amount to is an individual being required to take what is known as a booster shot to effectively redouble the immunity that an original dose of a vaccine may have proferred. 

There is already some evidence that providing smaller doses in several shots may be more effective than larger doses in fewer shots. Essentially, this is because our immune systems work in a similar fashion to a brick wall where bottom layers have to be built first before additional ones can be built.

Inko vishayam. . he has been suffering with "chronic atrial fibrillation" ante aabnormal heart rhythm for the past 10 years, so e kovvid drama lekhapoyina he would have rested in peace emo!!. Who knows, with such underlying condition also he might have lived for some more years, and he just passed away as he is anti vaxxer, so that oka pesident pothe janaalaki bayam tonn la kuddi start everyone start taking this serious and take vaccine. poor continent/contry pesident kada theseyadam easy and international stage meda pedha godava kuda kaadu
