‘Independent’ Jignesh Mevani gives a blow to BJP in Gujarat; wins from Vadgam

Bengaluru, Mar 27: A 65-year-old coronavirus patient who died in Karnataka this morning after apparently contracting the infection on a train ride has raised concern about community transmission of the highly contagious disease.
The man, the 60th coronavirus patient in Karnataka, died in Tumakuru. It is not known for certain how he caught the virus. The Karnataka Health Department has posted a notice on Twitter asking whoever travelled with him on train to come forward.

He had no history of recent foreign travel but had apparently traveled to Delhi on March 5 by Sampark Kranti Express and returned on March 11.

On March 7, he arrived at Delhi's Nizamuddin station and participated in an event at Jamia Masjid.

The man took a train back on March 11 and arrived at Yeshwantpur in Bengaluru. From there, he took a bus on March 14 to his hometown Sira.

He first showed symptoms of COVID-19 on March 18 and was taken to a private hospital. He was sent home with medicines but his condition worsened.

On March 23, he was admitted to a district hospital, but checked himself out against all advice and went to a private hospital. When his health showed signs of deterioration, he was again sent to the district hospital, where he tested positive for coronavirus yesterday. He died around 10.30 am today.

The health department has since traced 24 people who came in direct contact with him and are so, in the high-risk category. Thirteen are in hospital and eight have tested negative.

"All passengers who had travelled with him on the train are being traced," K Rakesh Kumar, Deputy Commissioner, Tumakuru, was quoted as telling news agency ANI.

A 70-year old woman and a 76-year old man had died of coronavirus or COVID-19 earlier in Karnataka.

India has over 700 coronavirus cases, including 17 deaths.

Hassan, Mar 13: In what could have been a major tragedy, an under construction flyover across Hassan-Mangaluru railway level crossing, near the new KSRTC Bus stand here collapsed today.

Fortunately no casualties occurred despite six concrete beems of 50 feet height, collapsed and broke into pieces.

The much awaited project was completely neglected by the successive governments for over a decade due to politics.  It was sanctioned eight months ago.

The Rs 42 crore project was taken up by a joint venture between state, center and South Eastern railway. The contractor or the Engineer were not present when the incident occurred.

Blaming the contractor, the locals alleged that poor quality of work led to the incident. No contractor or engineer was present even during construction, they added. Siddaiah, who runs an eatery near KSRTC bus stand said that it could have been a major tragedy if people were underneath the flyover when it crashed. The incident should be probe and the contractor should be punished, he added.

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.
