Bengaluru, Jun 12: The Central government has identified Karnataka's Udupi and Yadgir among the "emerging districts of concern" for COVID-19 in the country. Confirming the development, a top official of the state health department said, "they (centre) had reviewed these two districts a few days back...there was a sudden spurt of cases due to Maharashtra returnees turning positive." Sources said union cabinet secretary Rajiv Gauba, during a recent video conference with state chief secretaries and health secretaries, had shared his thoughts on the issue.

According to the information shared, districts with more than 400 cases, half of which was reported post-May 18 lockdown relaxation, have been identified as "emerging districts of concern." They are concentrated in the seven states/union territories of Maharashtra, Rajasthan, Tamil Nadu, West Bengal, Karnataka, Jammu and Kashmir and Haryana. "Udupi and Yadgir from Karnataka, along with Gurugram in Haryana and Kolhapur in Maharashtra have 90 per cent of the cases recorded after May 18," they said.

As on June 11 evening, Udupi had a total of 969 positive cases, out of which 619 are active, while 735 positive cases have been reported in Yadgir, out of which 626 are active. The two districts had reported a total of only 11 cases each as on May 18. While Udupi till last evening had seen 349 discharges, it was 108 in Yadgir.

Both districts have reported one COVID related fatality so far. As of June 11 evening, cumulatively 6,245 COVID-19 positive cases were confirmed in the state, which included 72 deaths and 2,976 discharges.

Bengaluru, Mar 7: Karnataka on Friday announced that there are no positive cases of the novel coronavirus, COVID-19 in the state till date.

"To date, 717 persons have been identified for observation, of them, 236 persons have completed 28 days of observation and 469 persons are continuing under home quarantine. 8 persons are admitted to selected isolation hospitals, " the state government said in a release today.

"Around 343 samples of symptomatic persons are sent for testing and 296 samples are reported as negative. No positive cases of Coronavirus in the state to date," it said.

Karnataka Chief Minister BS Yediyurappa earlier in the week assured people in state about the preparedness to tackle coronavirus.

He said, "We have issued instructions to all hospitals. We have made all the arrangements. People in Karnataka should not worry."

Union Health Minister Harsh Vardhan earlier today held a review meeting with states over preparedness for coronavirus. State governments have been asked to keep the testing and quarantine facilities, isolation wards and labs in active readiness.

The country's total number of positive cases of coronavirus touched 31 today. COVID-19 has so far killed more than 3200 people globally.

Bengaluru, Mar 27: Oncologist Dr. Vishal Rao, HCG Hospital Bengaluru on Friday said that human body cells release interferon chemical to kill viruses but it cannot be released by cells in the case of COVID-19 cases, leading to weak immune system. However, a therapy of specific concoction could be useful in treating COVID-19 patients.

"We got hold of some preprint suggesting that interferon is effective in COVID19," said Rao.

Speaking to news agency, he continued saying "When we withdraw blood for regular check-ups, we get buffy coat which can be used to take out cells and form interferon. These two chemicals and some other cytokines, in a specific concoction, could be potentially very useful in treating COVID-19 patients."

Rao said that they have built a concoction of cytokines which can be injected to reactivate immune system in COVID-19 patients.

"We are in a very initial stage and hope to be ready with its first set by this weekend. We have applied to the governement for an expedited review. We have also presented this before the state government" said Rao.

"We have a team of infection specialist, ICU team and other...all of us have worked together to build something that we believe. We want to serve the society at this hour of need," he added.

Dr Rao clarified that this is not a vaccine and this particular interferon therapy does not help to prevent the infection of COVID-19. However, this is focused and targeted towards COVID-19 positive patients or those who have just incubated the virus.

"We believe that in early stages as well as the patients who have just incubated, this particular therapy of interferon gama and other concoction of cytokines could be an effective method. In the late stages we are looking at specific dosage of the cells which are our own body cells which can actually be affective and could also be of use for the ventilator patients," he added.

Meanwhile, Dr Gururaj, Immunologist and Scientist told ANI that they are trying to cover two aspects, one is the early stage patients where they are trying to improve their immune systems.

"As Dr Vishal said, we are trying to see whether we can use the cytokines from our own immune cells which is a natural process but it is hampered in infected patients," said Dr Gururaj.

"In the last phase we are using cells which are used from the bone marrow of the patient or donors. We can use those cells to reduce the inflation and so called cytokines release syndrome which is basically the inflammatory response of the body," he added.
