New study reveals long-term harm of new coronavirus

After May 2020, a term called long covid became popular on foreign social media.
Long covid refers to the various new and recurrent infections that may occur four weeks or more after people are first infected with the virus that causes COVID-19.
Or persistent health problems, while most patients experience at least one symptom during the recovery period: including fatigue, dyspnea, chest pain, chest pain, arthralgia, palpitations, anosmia and dysgeusia, hair loss, deficits in cognitive symptoms, and psychosocial troubled
.

Figure: The various sequelae of the new crown virus It has been more than 2 years since the outbreak of the new crown virus.
Recently, more and more investigations have shown that the sequelae of the new crown virus may cause serious problems.
Sequelae are reviewed
.

Cardiovascular disease A new study published Feb.
7 shows that even mild cases of COVID-19 can increase a person's risk of developing cardiovascular disease for at least a year after diagnosis
.

Using the United States Department of Veterans Affairs' (VA) electronic health records set, the researchers analyzed data from nearly 154,000 people, mostly veterans of the military, mostly older white men.

.

These individuals were infected with Covid-19 between March 2020 and January 2021 without being vaccinated against Covid-19 and survived for at least 30 days after infection
.

The researchers also identified two control groups: 5.
6 million people who sought VA care during the pandemic but were not diagnosed with COVID-19, and 5.
9 million who sought VA care in 2017
.

The study found an increased risk of 20 cardiovascular diseases, including cerebrovascular disease, rhythm disorders, ischemic and non-ischemic heart disease, pericarditis, myocarditis, heart failure and thromboembolic disease
.

For example: Veterans with COVID-19 had a 72% higher risk of developing heart failure after 12 months than those in the control group who did not test positive
.

The risk of developing the symptom of a stroke was 52% higher than in the control group
.

Neuropsychiatric Disorders Dozens of papers have looked at the long-term effects of COVID-19 on mental health, but many have only measured conditions such as depression and brain fog months after infection
.

A study published Jan.
29 drew data from 11,324 patients available for evaluation in 19 published studies from Jan.
1, 2020, to Aug.
1, 2021
.

Neurological and neuropsychiatric symptoms are common three months after Covid-19 infection, the study showed
.

Fatigue, cognitive impairment (brain fog, memory problems, attention disturbance) and sleep disturbances are the most prevalent features of post-neurological/neuropsychiatric COVID-19 syndrome
.

This symptom is more common in the group of patients 6 months or more after infection than in the group of patients 3 to 6 months after infection
.

Figure: Weighted Frequency of Neurological and Neuropsychiatric Symptoms Reported in Post-COVID-19 Syndrome This persistent symptom is thought to be likely due to prolonged retention of SARS-CoV-2 RNA in brain tissue, exacerbating neuronal loss in patients over time
.

The editor summarizes the research on cardiovascular complications and believes that the best way to prevent the long-term sequelae of the new coronavirus is to first prevent the new coronavirus infection.
Long-term diseases may have long-term consequences for patients and the public health system
.

However, Omicron was only detected in South Africa on November 9, 2021.
According to the study time of the patients in the above two studies, this patient data probably did not include the group of patients infected with the new variant of Omicron.
And now Omicron infection cases account for about 99.
9% of new cases in the United States, so there may still be no effective assessment of the long-term impact of the Omicron variant
