BJP conspiring to oust me, says Chief Minister Siddaramaiah

Bengaluru, Jun 20: The Karnataka Health Department has issued guidelines on the admission of COVID-19 patients in private hospitals after clinical assessment, mandating that the district surveillance officer (DSO) should be first informed to initiate further procedures, an official said on Friday.

"A health team sent by the DSO should visit the home or hospital where the patient is staying. The team should conduct a rapid assessment of his or her health condition," said Karnataka's Additional Chief Secretary Jawaid Akhtar.

In the rapid health condition assessment, the team should first check the patient's body temperature, followed by SpO2 (oxygen saturation) level and confirm if there are any comorbidities such as hypertension, diabetes, tuberculosis, HIV, cancer, stroke etc.

Depending on the health condition of patients, Akhtar said, two categories have been made.

"Those who have body temperature greater than 37.5 degrees Celsius, SpO2 level below 94 percent, elderly (above 60 years) and suffering from known comorbid conditions should be taken to a dedicated Covid hospital (DCH)," he said.

"All other patients, even if older but not suffering from co-morbidities, those below 60 and suffering from co-morbidities and asymptomatic cases should be taken to a dedicated Covid health centre (DCHC) or a private hospital as opted by the patient," he added.

Private hospitals have been asked to pitch in due to the rising number of cases in Karnataka. Currently, there are 2943 active cases in the state after 337 cases were reported on Friday.

"The patients are assessed clinically and evaluated at DCHCs or private hospitals with appropriate diagnostic tests. After evaluation, if the patients are asymptomatic, they are shifted to a COVID Care Centre (CCC) for further management," said Akhtar.

CCCs are expected to be equipped with ventilated rooms, pulse oximeters, handheld thermal scanners and blood pressure apparatus.

A nurse has to be present round the clock for every 50 patients and should visit each patient twice a day for assessment whereas the medical officer has to visit the CCC once a day. He should also be available on call in case of an emergency.

Staff serving food and others should wear personal protective equipment and an N-95 mask. Explaining the procedures at DCHCs, Akhtar said general examinations for medical conditions like body temperature, BP, pulse, oxygen saturation and urine output should be in place.

Investigations such as complete blood count, fasting blood sugar, random blood sugar, liver function tests, renal function tests, ECG and chest X-ray facilities should be available.

"DCHCs should ensure that above examinations are over in an orderly timeline of 24 hours and depending on the examination, the patient is continued to be lodged at the DCHC or sent to DCH or CCC," said the senior officer.

Likewise, the discharge policy should be done as per the protocols issued by the Health Department from time to time.

The Karnataka government is yet to fix an upper limit on the cost of treating COVID-19 patients in private hospitals. While reports indicated that this could be capped at Rs 5200 per day, health officials are yet to specify this is the case. Private hospitals in the state have asked the government to take a collaborative approach in deciding the fixed cap on treatment cost.

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

Bengalur, May 2: Two people died of COVID-19 in Karnataka on Saturday taking the toll in the state to 25, whereas nine more tested positive for the virus, pushing the tally to 598, the health department said. Two deaths were reported in Bidar and Bengaluru urban, the health department said in a statement.

An 82-year-old person with a history of Severe Acute Respiratory Illness died in Bidar. While the second fatality was a 62-year-old man with a history of diabetes, hyper-tension, renal failture and was on multiple myeloma on chemotherapy, in Bengaluru. He too had complained of breathlessness on April 30 and died on Saturday at the designated hospital.

Among the nine new cases, two each are from Tumakuru, Vijayapura, one each from Bidar, Chikkaballapura, Belagavi, Bagalkot and Bengaluru urban. Cumulatively, 598 COVID-19 positive cases have been confirmed in the state and it includes 25 deaths.
