Differences in the epidemic in Da Nang and Hai Duong, Quang Ninh

The two batches are about 6 months apart.

And four months later, on January 28, two outbreaks in Hai Duong and Quang Ninh were discovered after the Ministry of Health recorded `patient 1552` as a worker of Poyun Company, Hai Duong, and `patient 1553`

According to experts, the biggest difference between the two epidemics is the speed of infection.

Determining F0 is not necessary

Since July, Da Nang has been considered the largest outbreak in Vietnam, spreading to many provinces and cities.

This epidemic occurs during the Tet holiday when travel demand is high, which is a favorable risk factor for the disease to spread strongly.

Therefore, `tracing F0 is no longer necessary but must quickly take samples for testing on a large scale`, said associate professor, Dr. Nguyen Huy Nga, former Director of the Department of Preventive Medicine, Ministry of Health, said.

`Super infectious` variant virus strain

Dr. Le Quoc Hung, Head of the Department of Tropical Diseases, Cho Ray Hospital (Ho Chi Minh City), said that according to research, the new British strain of nCoV has increased virulence by about 30% and increased infectiousness by 70%.

This epidemic is similar to Da Nang in that F0 is lost, F0 has not been found, and the source of infection has not been determined.

However, the current epidemic is more difficult due to the British nCoV variant, so the spread time is much faster.

In addition, each region has different risk factors.

During the meeting on the afternoon of February 1, Minister of Health Nguyen Thanh Long stated that the normal infection cycle is about 4-5 days, but this time it is only 1-2 days.

On the same afternoon, Ho Chi Minh City Hospital for Tropical Diseases announced the results of gene sequencing of `patient 1660`, 28 years old, infected with the nCoV variant from the UK.

The nature and severity are different

For Da Nang, nCoV attacked the hospital, where there were many elderly patients with many serious chronic diseases, causing heavy loss of life.

Regarding Hai Duong and Quang Ninh, the number of infected cases is higher but the nature is mild because the epidemic has not yet attacked the hospital, said Dr. Truong Huu Khanh, Head of Infection – Neurology Department, Children’s Hospital 1 (HCMC).

Currently, the epidemic control situation is considered by officials to be `very positive steps`.

The goal is `in 6 days we will be able to localize the outbreak in Hai Duong and Quang Ninh, keeping the commitment to stamp out the epidemic in 10 days`, Deputy Prime Minister Vu Duc Dam emphasized when inspecting Covid-19 prevention work in the city.
