There is now an imminent threat of measles spreading in various regions globally, as COVID-19 led to a steady decline in vaccination coverage and weakened surveillance of the disease, the World Health Organization (WHO) and the U.S. public health agency said on Wednesday.
Measles is one of the most contagious human viruses and is almost entirely preventable through vaccination. However, it requires 95 per cent vaccine coverage to prevent outbreaks among populations.
A record high of nearly 40 million children missed a measles vaccine dose in 2021 due to hurdles created by the COVID pandemic, the WHO and the U.S. Centers for Disease Control and Prevention (CDC) said in a joint report.
