Phan Trong Lan, head of the General Department of Preventive Medicine, said Tuesday that Vietnam would face two challenges if it announces the pandemic to be over.

First, in the scenario that a dangerous Covid-19 strain arises, it could lead to more severe cases and deaths, eventually overwhelming the capabilities of the medical system.

"When we announce the Covid-19 outbreak to be over, certain mechanisms and policies in the Covid-19 fight would no longer be applied, for example the research, production, purchase and approval of vaccines, drugs and other medical products... under emergency state, which affects the deployment of Covid-19 prevention measures."

Second, the mobilization of society sections at multiple levels to fight the virus would no longer receive the level of attention it needs. Therefore, people may get complacent and the reactivation of certain administrative and social measures to fight the virus would become more difficult.

Lan was speaking in response to doctor Nguyen Lan Hieu's suggestion that Vietnam should declare in the country to save medical resources.

At a National Assembly session Saturday, Hieu, director of the Hanoi Medical University Hospital, requested that the government announces a shift in its Covid-19 fight, introducing clear policies to replace old ones. The shift would help limit resource loss while ensuring enough preparation should another outbreak of Covid-19 or another disease occur, he said.

But Lan said it's not time for that yet.

Globally, the Covid-19 situation is still developing in a complex manner around the world, and immunity gained either through infection or vaccination is waning over time. The coronavirus is also mutating, creating new variants that could be more infectious and more likely to evade the immune system, he said.

At its latest meeting on October 13, the Emergency Committee of the WHO said the Covid-19 pandemic was still happening around the world and advised countries to ramp up their monitoring systems, as well as expand treatment capacities and vaccine coverage.

Vietnam is a responsible member of the WHO, and its effective Covid-19 fighting measures have contributed to the efforts of the global community in containing the novel coronavirus, Lan said.

So far, the Ministry of Health has loosened its Covid-19 prevention measures to make room for socio-economic growth. The situation has been brought under control and prevention measures have adapted to the "new normal" period. Vietnam currently records around 500 new cases a day on average, and the number of active severe cases is around 70.

Tran Dac Phu, senior advisor at the Public Health Emergency Operations Center, said Vietnam was executing a safe adaptation plan, and its main mission was to accurately assess risks.

"Too much control would lead to inappropriate investments, affecting the economy and social security," he said, adding that the stance on Covid-19 prevention nowadays was "neither too much nor too little."
