Bengaluru: In Karnataka state and Bengaluru city, many people are now reinfected with Covid 19. This reinfection is confirmed in the diagnostics. However, the state health department doesn't have any information in this regard.
The health department estimated that in Bengaluru city around 35 and in the state less than 100 patients are reinfected with Covid 19. However, there are no answers to a few key questions.
Whether such patients subjected to the RTPCR test in the first time or whether antibody tests are conducted after or whether they tested positive only in the second RTPCR tests? These are the few questions which yet to be answered.
There are no separate diagnostic modules to confirm the re-testing. So, it is difficult to find out the Covid 19 symptoms, or whether Coronavirus mutated or virus impact increased or related matters, said senior physician Dr Anjanappa to ETV Bharat.
In Bengaluru city on September 6, for the first time, Covid 19 reinfection confirmed in a 27 years old woman. After the first infection, she tested positive again after a month. But she had mild symptoms. The doctors observed that as she didn't develop a strong antibody, she was reinfected.
Fewer symptoms
"If the antibody found in good amount in one's body after the first infection, even though such persons re-infected, the symptom will be less at Victoria hospital, no reinfection cases reported," said hospital Covid 19 ward nodal officer and microbiologist Dr Asima Banu.
"There is no information on whether a person develops Covid after testing negative in the RTPCR tests. A few patients were testing positive even 32 days after the Covid 19 infection. In a few patients, even after they cured of Covid 19, test results were coming positive in the RTPCR tests due to the deadly virus in their body. Antibodies found in a few patients who cured of the Covid 19. A few who tested positive for Covid 19 may be reinfected by another mutated virus," Banu said.
"Among the dengue patients, if they reinfected, the severity of the fever will be high. But there is no research on this among the Covid 19 patients," she said.
According to an estimation done by the state health department, Covid 19 antibodies can be found in the recovered patients for over 3 months. After that antibodies may become weak.
Such persons may be reinfected later. As per the protocol, a person who recovered from Covid 19 is not tested again. They are discharged directly. So, there is confusion whether they are reinfected or the old virus continued in their body says Javed Akhtar, additional chief secretary for the health department.
