The recent variants of coronavirusWhat omicronhave left evidence of what is possible get infected again after a first time. Although the vaccines help the body develop immunity against him virusthese are not either enough for eradicate this sickness.
Recently, the doctor and epidemiologist Ziyad Al-Alyfrom the University of Washington, has carried out a study in which they are evaluated effects Y risks of the reinfections by Covid-19. For the investigation, the record of more than 5.6 million of people in the United States Veterans Administration Health System, comparing the positive of 250,000 patients with the reinfection of others 38,000.
Up to three relapses
The results of the study carried out by Al-Aly showed that the 38,000 people, the 92% of the total sample, had passed the coronavirus two times, while 2,200 they had done it until three occasions. On the other hand, other 246 people became infected with Covid-19 until four times.
“If you had asked me about reinfection a year and a half agoI would have told you that maybe I had a patient here or there, but that was very, very rare. However, that not true anymore”, stated the epidemiologist.
Heart and respiratory problems
Besides the proportion of reinfections who represented each cluster of those mentioned, Al-Aly’s research also collects which are the symptom that appear in these patients. On the one hand, regarding the system cardiovascularare usual chest pain, heartbeat, heart attacks, myocarditis Y pericarditisin addition to insufficiency cardiac and thrombosis. On the other hand, the system respiratory looks resentful to the extent that they appear difficulty for breathe, lack of oxygen in the blood, diseases pulmonary and accumulation of liquids around the lungs.
Also, the researchers argue that the risk associated with contagion due to coronavirus he leaves accumulating in time, which causes each relapse be more dangerous for the organism. According to the study, the possibility of developing new problems is very high in 30 days post-infection, and high in the six months later.
“It is possible that individuals sicker or people with immune dysfunction have a higher risk of reinfection and health outcomes adverse after reinfection,” says Al-Aly. “The prevention of the infection Y reinfection by SARS-CoV-2 should remain the objective of the politics of public health”, conclude the researchers.
