London, Europe Brief News – Do you have signs or symptoms of common cold? It could be good news for your health immunity.
A new study revealed that natural defences against a common cold could offer some protection against Covid-19.
The Nature Communications study involved 52 individuals who lived with someone who had just caught Covid-19.
Those who had developed a “memory bank” of specific immune cells after a cold – to help prevent future attacks – appeared less likely to get Covid.
Experts say no-one should rely on this defence alone, and vaccines remain key.
But they believe their findings could provide useful insight into how a body’s defence system fights the virus.
The World Health Organization (WHO) has earlier warned of ‘tsunami’ of COVID cases in the near future. The declaration was due to Omicron spread.
The WHO further warned of the risk posed by the Omicron variant after COVID-19 case numbers shot up by 11 percent globally last week.
Omicron is behind the rapid virus spikes, the WHO said in its COVID weekly epidemiological update on Wednesday.
The update came after a number of countries reported record-high infection figures in recent days.
In some parts, the increase followed the emergence of the new Omicron variant, first detected in South Africa.
