Ndugu zangu,

Hii ni habari njema na wote wenye mioyo safi tumshukuru Mungu kwa hili; utafiti uliochapishwa na jarida la Science News umegundua kuwa watu waliokwisha ugua Covid-19 hawapati maradhi haya kwa mara ya pili. Kama ni hivi ni habari njema na huenda kweli Covid-19 ni kama mafua mengine hivyo tutumie silaha zetu ikiwemo mitishamba ili kuweza kupunguza au kufifisha makali yake kwani miili yetu hujenga kinga zaidi unapopata dhahama hii. Nimeweka link hapo chini ili kurahisha kupata taarifa kamili.

People who test positive again for the coronavirus, despite having already recovered from COVID-19, aren’t being reinfected, a new study finds.

Reports of patients discharged from hospitals in South Korea testing positive after their apparent recovery had raised concerns that people could get infected by the virus in the short term more than once or that the infection could come back. But diagnostic tests for the coronavirus that causes COVID-19 rely on detecting the virus’s genetic material (SN: 4/17/20). A positive result does not indicate whether a person is shedding viruses capable of infecting cells — which would signal an active infection.

Now, a May 19 report from the Korean Centers for Disease Control and Prevention shows that samples from “reinfected” patients don’t have infectious viruses. The finding hints that the diagnostic tests are picking up on the genetic material from noninfectious or dead viruses. That lack of infectious virus particles means these people aren’t currently infected and can’t transmit the coronavirus to others, the researchers say.

“It’s good news,” says Angela Rasmussen, a virologist at Columbia University. “It appears people are not being reinfected, and this virus is not reactivating.”

In the study, researchers tried to isolate infectious coronaviruses from samples taken from 108 people who retested positive. All of those samples tested negative. When the scientists examined 23 of those patients for antibodies against the coronavirus, almost all had neutralizing antibodies that can stop the virus from getting into cells (SN: 4/28/20). That immune response may protect a person from getting reinfected, at least in the short term.

The team also tracked down 790 contacts of 285 people who retested positive. Of those contacts, 27 tested positive for the coronavirus. Twenty-four of those were cases that officials had previously confirmed. Officials also identified three new cases, all of whom either had contact with the Shincheonji religious group — which was hit particularly hard in the early days of the pandemic — or a confirmed case in their family. No new cases appeared to stem from repeat positive patients, a sign those patients aren’t contagious.

Now, “we can largely stop worrying about reinfection and address the next big questions,” Rasmussen says. “How protective are immune responses in recovered patients, and how long does immunity last?”

Trustworthy journalism comes at a price.
Scientists and journalists share a core belief in questioning, observing and verifying to reach the truth. Science News reports on crucial research and discovery across science disciplines. We need your financial support to make it happen – every contribution makes a difference.
 
But, just because you recover from the virus does not mean you cannot catch it again, WHO confirmed in a statementreleased on 24 April.

According to Li QinGyuan, director of pneumonia prevention and treatment at China Japan Friendship Hospital in Beijing, those who have been infected with Covid-19 develop a protective antibody - but it isn’t clear how long the protection lasts.

Kama hujui kitu kaa kimya sio kuleta upotoshaji.
 
kama vipi Una boost immune kwa vyakula, mazoezi, matunda, mitishamba n.k halafu unautafuta makusudi uupate upone, ili uondoe hii Vulnerability uendelee na mambo yako.

"There is currently no evidence that people who have recovered from Covid-19 and have antibodies are protected from a second infection," the organisation said.

According to Li QinGyuan, director of pneumonia prevention and treatment at China Japan Friendship Hospital in Beijing, those who have been infected with Covid-19 develop a protective antibody - but it isn’t clear how long the protection lasts.

Sawa, ila hii dalili hii ni homa kama homa nyingine tu. Utaamkizwa kama mafua ila haitakuwa na madhara kwani kinga inakuwa imeshajijenga. Ni sawa na mafua mengine yapo hewani kila siku unaugua na kupona. Na huu utafiti umechapishwa jana tarehe 19 May, 2020.

Unafahamu kuwa kila mwaka kuna chanjo mpya ya mafua? Virus vina ji mutate, huwezi kupata flu vaccine once and forever.
