Health scare

Kerala: At least three die of infection caused by Nipah virus

Three more people are suspected to have succumbed to the ailment.

At least three people have died on Monday due to infection caused by the Nipah virus in Kerala. Three more are suspected to have succumbed to the ailment. As many as nine people suspected of carrying the virus have been admitted to hospital.

Kerala Health Minister KK Shailaja said her department was taking all precautions to control the infection, The News Minute reported. Union Minister of Health and Family Welfare JP Nadda had said on Sunday that the Centre had asked the National Centre for Disease Control to assist the state government in taking required measures.

The virus is spreading through direct contact or through body fluids, Shailaja said.

There is no Nipah vaccine for either humans or animals at the moment, according to theWorld Health Organization. Virology experts from Manipal and Apollo hospitals have collected blood samples of those believed to be affected. All samples are being sent to Manipal Centre for Virus Research and the National Institute of Virology for testing.

Earlier, the Director of Health Service in Kerala, Dr RL Sarita, told reporters that the cause of the deaths was a “rare virus”. “We need to ascertain which type of virus caused the deaths,” she said, according to PTI. “Many viruses are zoonotic [a disease that can be transmitted from animals to people] types and some can be transmitted through bats.”

Two brothers in their mid-twenties died of the disease on May 5 and May 18, followed by their aunt on May 19. The wife of one of the brothers, and their father are in hospital. A nurse at the Perambra Taluk Hospital in Kozhikode district, who treated the three Nipah-confirmed patients, died in the early hours of Monday at the Medical College Hospital in Kozhikode.

The health department has opened an isolation ward in Kozhikode Medical College and Hospital for the eight people who are in a critical condition and 25 more who are under observation. The state has formed a task force headed by Kozhikode District Collector UV Jose, and has recalled all doctors and paramedical staff on or going on leave. It is also seeking help from private hospitals.

What is Nipah?

The World Health Organization calls Nipah a “newly emerging zoonosis”, which is a disease that can be transferred from animals to humans. It causes fever and cold-like symptoms in its patients that quickly advances to encephalitis, which is inflammation of the brain, and myocarditis, or inflammation of the heart. Because its symptoms are similar to Japanese encephalitis, it has in the past been mistaken for that disease, though it affects those have been vaccinated against JE. Currently, there is no vaccine or cure for Nipah infections and treatment is restricted to intensive supportive care of patients till the symptoms subside. Those infected initially have a sudden onset of flu-like symptoms.

The first Nipah outbreak was in Malaysia in 1999. There have been other outbreaks in Bangladesh (in 2001, 2003 and 2007) and India (2001 and 2007). “It is highly pathogenic to humans, with high case fatality rate, ranging from 40 to 75%”, says the WHO.

Following a mountaineer as he reaches the summit of Mount Everest

Accounts from Vikas Dimri’s second attempt reveal the immense fortitude and strength needed to summit the Everest.

Vikas Dimri made a huge attempt last year to climb the Mount Everest. Fate had other plans. Thwarted by unfavourable weather at the last minute, he came so close and yet not close enough to say he was at the top. But that did not deter him. Vikas is back on the Everest trail now, and this time he’s sharing his experiences at every leg of the journey.

The Everest journey began from the Lukla airport, known for its dicey landing conditions. It reminded him of the failed expedition, but he still moved on to Namche Bazaar - the staging point for Everest expeditions - with a positive mind. Vikas let the wisdom of the mountains guide him as he battled doubt and memories of the previous expedition. In his words, the Everest taught him that, “To conquer our personal Everest, we need to drop all our unnecessary baggage, be it physical or mental or even emotional”.

Vikas used a ‘descent for ascent’ approach to acclimatise. In this approach, mountaineers gain altitude during the day, but descend to catch some sleep. Acclimatising to such high altitudes is crucial as the lack of adequate oxygen can cause dizziness, nausea, headache and even muscle death. As Vikas prepared to scale the riskiest part of the climb - the unstable and continuously melting Khumbhu ice fall - he pondered over his journey so far.

His brother’s diagnosis of a heart condition in his youth was a wakeup call for the rather sedentary Vikas, and that is when he started focusing on his health more. For the first time in his life, he began to appreciate the power of nutrition and experimented with different diets and supplements for their health benefits. His quest for better health also motivated him to take up hiking, marathon running, squash and, eventually, a summit of the Everest.

Back in the Himalayas, after a string of sleepless nights, Vikas and his team ascended to Camp 2 (6,500m) as planned, and then descended to Base Camp for the basic luxuries - hot shower, hot lunch and essential supplements. Back up at Camp 2, the weather played spoiler again as a jet stream - a fast-flowing, narrow air current - moved right over the mountain. Wisdom from the mountains helped Vikas maintain perspective as they were required to descend 15km to Pheriche Valley. He accepted that “strength lies not merely in chasing the big dream, but also in...accepting that things could go wrong.”

At Camp 4 (8,000m), famously known as the death zone, Vikas caught a clear glimpse of the summit – his dream standing rather tall in front of him.

It was the 18th of May 2018 and Vikas finally reached the top. The top of his Everest…the top of Mount Everest!

Vikas credits his strength to dedication, exercise and a healthy diet. He credits dietary supplements for helping him sustain himself in the inhuman conditions on Mount Everest. On heights like these where the oxygen supply drops to 1/3rd the levels on the ground, the body requires 3 times the regular blood volume to pump the requisite amount of oxygen. He, thus, doesn’t embark on an expedition without double checking his supplements and uses Livogen as an aid to maintain adequate amounts of iron in his blood.
