Children with Covid-19 may be less contagious than adults: Two Experts – Latest Pharmacy News | Business | Magazine | Instant News


There are tentative signs that children may not spread the corona novel virus as much as adults, two leading epidemiologists said on Tuesday, even though they warned that the bad news was that human immunity might not last that long.

When Europe and the United States began returning to work after lockouts were put in place to slow the spread of Covid-19, a respiratory disease caused by a new virus, world leaders sought to work when it was safe for children and students to return to their studies.

Dr Rosalind Eggo, an infectious disease modeler at the London School of Hygiene and Tropical Medicine, said she had seen several indications from studies that children might not spread the corona novel virus as much as adults.

“There are indications that children are less infectious but uncertain,” Eggo, who sat on a panel advising the British government about Covid-19 transmission among children and inside the school, told the House of Lords science committee, room the two British parliaments.

Eggo said that for children who showed no signs of being infected, it was very difficult to say how contagious they were, even though he said there was little evidence beginning to emerge that there might be a lower chance of infection from them.

“We need more research to really explain it because this is very important,” Eggo said.

He said his research had shown that there was a much lower rate of symptomatic infections in those under the age of 20 – perhaps only 20 percent of infections had clinical symptoms.

“We think small children are likely to get it so far but it’s not certain,” he said. “We are very confident that children tend to have poor results.”

Eggo could not be immediately contacted to provide further comments about the research he intended.

John Edmunds, a member of the British Scientific Advisory Group for Emergencies (SAGE), told the same science committee that it was surprising how children did not seem to play many roles in spreading novel coronaviruses.

“It’s not uncommon that children don’t seem to play many roles in transmission because for most respiratory viruses and bacteria they play a central role, but in this case they don’t seem to do so,” said Edmunds, a professor in London. School of Hygiene and Tropical Medicine.

“There is only one documented outbreak related to school – extraordinary; You normally expect most outbreaks related to schools but in global literature there is only one documented study, “said Edmunds, citing a study of French secondary schools. “This is extraordinary.”

He said that, more broadly, evidence of transmission from asymptomatic people – which might be around 30 or 40 percent of adults – was unclear.

But he added there was potentially bad news – that human immunity to novel coronaviruses might not last long.

“The antibody response decreases over time from survivors of SARS so that after a few years their antibodies have decreased significantly,” said Edmunds, referring to the Severe Acute Respiratory Syndrome, which is also caused by a type of corona virus.

“We can also see from other corona viruses – which cause coughs and colds – that more people don’t seem to have long-term immunity to many of these viruses and therefore allow them to be infected later.

“So that’s potentially bad news for us: immunity that may not last long for this virus,” he said.
