Covid-19 has infected more than 3 million people and killed at least 210,000 worldwide, according to Johns Hopkins University.
The US, which remains the hardest-hit country, reported 988,451 cases and 56,245 deaths, both tallies are the highest in the world now.
Ghebreyesus added that although there is no question that stay-at-home orders and other physical distancing measures have limited coronavirus transmission in several countries, the virus remains "extremely risky".
The World Health Organisation (WHO) has warned that there is no evidence that people who tested positive for the new coronavirus are immune and protected against reinfection. No cases in Latin America, actually. Tedros said the tragic reality is "children will die as a result".
"Every country could have triggered all its public health measures possible".
Long-term care system "broken" and needs to be better: Ford
Ford said Thursday that officials are still deciding which homes will receive help from the military. In both outbreaks, the health unit has confirmed one staff member tested positive for the virus.
"The world should have listened to WHO then, carefully", he added.
He called on countries to support global immunization services for children.
The World Health Organization Director-General Tedros Adhanom Ghebreyesus said on Monday that the current COVID-19 pandemic is far from over and the accurate number of cases might be under-reported in some countries due to lack of testing capacity.
Paul Molinaro, chief of World Health Organization operations support and logistics, said global vaccine shipments were disrupted in April and if this continued into May there would be gaps in routine immunisations and campaigns against other disease outbreaks.
"Each country takes its own responsibility".
