The World Health Organization said on November 30 that the comprehensive travel ban could not stop the international spread of the new crown variant virus Omicron strain, but would only impose a heavy burden on people's lives and livelihoods, and then adversely affect the global anti epidemic efforts. Who said in a statement that the organization listed the Omicron strain as a variant strain "requiring attention" on the 26th. Since then, more and more countries have taken temporary travel restrictions, including banning passengers from southern African countries and other countries where the strain was found. Who believes that the comprehensive travel ban can not stop the international spread of Omicron strain, but will only impose a heavy burden on people's lives and livelihoods, inhibit the enthusiasm of countries to report and share new crown epidemiology and sequencing data, and then have an adverse impact on global anti epidemic efforts. Who also recommends that people with physical discomfort or high risk, including people aged 60 and over or those with complications, should postpone their travel plans. The director general of the World Health Organization, Mr Tak Desai, said on the day that some countries were adopting COVID-19's rigid measures not based on evidence or their ineffectiveness to deal with it, which only aggravated inequality. Countries should take reasonable and appropriate risk reduction measures in accordance with the international health regulations. (outlook new era)
