A Third of C****av***s Cases May be ‘Silent Carriers’
ChinaWire

The number of people infected with c****av***s who show no or delayed symptoms could be as high as one-third of those who test positive for the disease.

According to classified Chinese government data, the true scale and of the hidden number of these 'silent carriers' could be higher than first thought.

This discovery has huge ramifications for the strategies being used by countries to contain the v***s.

Scientists are currently unable to agree on what role asymptomatic t***smission plays in spreading the disease and how infectious people with no symptoms are.

A growing number of scientists are now challenging the World Health Organisation's earlier statement that asymptomatic t***smission was 'extremely rare'.

A report by the WHO's international mission to China estimated that asymptomatic infections accounted for 1 to 3 per cent of cases.

In February, a group of Japanese experts led by Hiroshi Nishiura, an epidemiologist at Hokkaido University, wrote a letter to the International Journal of Infectious Diseases.

Nishiura said: 'The number of novel c****av***s (C****-**) cases worldwide continues to grow, and the gap between reports from China and statistical estimates of incidence based on cases diagnosed outside China indicates that a substantial number of cases are underdiagnosed.'

Nishiura put the proportion of asymptomatic Japanese patients evacuated from W***n at 30.8 per cent, a figure similar to the classified Chinese government data.

Nishiura added: 'The asymptomatic ratio … could be higher among children than in older adults. That would considerably change our scope of the outbreak, and even the optimal interventions can change.'

The WHO counts all people who test positive as confirmed cases regardless of whether they experience any symptoms, as does South Korea.

Western countries such as the United States, Britain and Italy do not test people without symptoms, apart from clinicians who have been repeatedly exposed to the v***s.

Experts now believe that China and South Korea's strategy of testing everyone who has had contact with a patient, even if they themselves are not sick, is more efficient at curbing the spread of the v***s.

The USA and European countries are only testing airport arrivals if they show symptoms in contrast to Hong Kong who are testing all arrivals.

Other countries, such as the UAE, are routinely screening arrivals for high temperatures at airports.
