Most COVID-19 infections caused by people with no Symptoms

People with no symptoms are causing the most COVID-19 infections. Masks is the only protection available against this virus. This was revealed by the US Centers for Disease Control and Prevention (CDC).

The warning follows the second wave of Covid-19 infection, which is spreading at an unparalleled speed. So far, the World Health Organisation (WHO) has recorded 55.6 million confirmed cases and 1.34 million deaths across the globe.

According to the report, the United States is the worst-affected country with 11.8 million confirmed cases and over 252,000 deaths. India is the second worst affected country with more than nine million confirmed cases.

The present Trump administration discourages the use of masks and many US health experts blame this attitude for the devastations that the coronavirus has caused in the United States. The incoming Biden administration has pledged to promote the use of masks and other preventive measures.

The new CDC guidelines issued during the weekend stated, “Asymptomatic or pre-symptomatic infected wearers who feel well and may be unaware of their infectiousness to others are estimated to account for more than 50 per cent of transmissions.”

The CDC noted that studies done by various international agencies show that 40-45 per cent of infected people never develop symptoms.

The U.S. agency said, “Among people who do develop symptomatic illness, transmission risk peaks in the days just before symptom onset (pre-symptomatic infection) and for a few days thereafter. The number of infections transmitted peaks when virus levels peak.”
