Watu ambao wameambukizwa COVID-19 zaidi ya mara moja, wana uwezekano mara mbili au tatu zaidi, kuwa na matatizo mengi ya kiafya kuliko wale ambao wameambukizwa mara moja tu, ripoti ya utafiti mkubwa wa kwanza juu ya suala hilo ilisema.
Maambukizi mengi yameongezeka huku janga hilo likiendelea kusababisha maafa na virusi vikiendelea kubadilika na kuwa aina mpya, lakini athari za kiafya za muda mrefu za kuambukizwa tena hazijawa wazi.
Watafiti wa Marekani walisema utafiti wao mpya uliochapishwa katika jarida la "Tiba ya Asili" ulikuwa wa kwanza kuangalia jinsi kuambukizwa tena, kunaongeza hatari ya matatizo ya kiafya.
Watafiti walichambua rekodi za matibabu za watu milioni 5.8, katika hifadhi ya takwimu kitaifa ya Idara ya masuala ya wazee ya Marekani.
Wakati watafiti walilinganisha matokeo ya kiafya ya vikundi tofauti, waligundua kuwa "watu walioambukizwa tena wana hatari kubwa ya matatizo ya kiafya," Ziyad Al-Aly, mtaalam wa magonjwa ya magonjwa katika Chuo Kikuu cha Washington huko St Louis na mkuu wa utafiti , aliliambia shirika la habari la AFP.
Watu walio na maambukizi ya kurudia walikuwa na uwezekano wa kufa kabla ya wakati na mara tatu zaidi ya uwezekano wa kulazwa hospitalini na ugonjwa kuliko wale ambao hawakuwa wameambukizwa tena, utafiti uligundua.
Repeat COVID is riskier than first infection, study finds
The risk of death, hospitalization and serious health issues from COVID-19 jumps significantly with reinfection compared with a first bout with the virus, regardless of vaccination status, a study published on Thursday suggests.
"Reinfection with COVID-19 increases the risk of both acute outcomes and long COVID," said Dr. Ziyad Al-Aly of Washington University School of Medicine in St. Louis. "This was evident in unvaccinated, vaccinated and boosted people."
The findings were drawn from U.S. Department of Veterans Affairs (VA) data collected from March 1, 2020 through April 6, 2022 on 443,588 patients with one SARS-CoV-2 infection, 40,947 with two or more infections, and 5.3 million noninfected individuals. Most of the study subjects were male.
Reinfected patients had a more than doubled risk of death and a more than tripled risk of hospitalization compared with those who were infected with COVID just once. They also had elevated risks for problems with lungs, heart, blood, kidneys, diabetes, mental health, bones and muscles, and neurological disorders, according to a report published in Nature Medicine.
"Even if one had prior infection and was vaccinated - meaning they had double immunity from prior infection plus vaccines - they are still susceptible to adverse outcomes upon reinfection," Al-Aly, the study leader, said.
People in the study with repeat infections were more than three times more likely to develop lung problems, three times more likely to suffer heart conditions and 60% more likely to experience neurological disorders than patients who had been infected only once. The higher risks were most pronounced in the first month after reinfection but were still evident six months later, researchers found.
