COVID-19: Beaches, bouncers and quarantine bouquets

By Neena Bhandari

Sydney, 27.03.2020 (Live Mint): Autumn (March – May) is one of my favourite seasons in Sydney, my home for two decades. Bright blue skies, gentle sea breeze and the mellow warmth of the sun provide a perfect setting for outdoor barbecues, picnics, music and theatre events. But as new shoots were just appearing on the charred landscape after a prolonged spring-summer of bushfires, droughts and floods, which had devastated communities and the economy, the novel Coronavirus (COVID 19) put a full stop to life as we know it.

`Social distancing’ is the diktat we must all abide by, if the spread of current contagion has to be halted. All non-citizens and non-residents have been banned from arriving in the country and Australians have been advised not to travel overseas. This big island continent is fortified. Friends far afield from Nepal to the UK are trying to get a flight home. But with the country’s flagship carrier, Qantas, slashing 90 percent international flights, these are trying times.

New way to stop falciparum malaria transmission

SYDNEY, 26.12.19 (SciDev.Net):  Australian scientists have successfully blocked the deadliest malaria parasite —- Plasmodium falciparum — in its transmission stage, paving the way for developing preventative therapies to stop the spread of the disease.

Lead researcher Justin Boddey from the Walter and Eliza Hall Institute of Medical Research and University of Melbourne says, “We have built on our previous studies, where we identified in the P. falciparum parasite an enzyme called plasmepsin V, an enzyme essential for the parasite to grow inside red blood cells. We showed that if you inhibit the enzyme’s activity then you can kill the parasites as they are growing in red blood cells.”

Samoa measles death toll rises amid vaccine scare

By Neena Bhandari

Sydney, 03.12.2019 (SciDev.Net): Fifty-three people, including 48 children under the age of four years, have died of measles in the small Pacific island nation of Samoa, which is facing the worst outbreak of this highly contagious disease driven by low vaccination levels.

Samoa’s Prime Minister Tuilaepa Lupesoliai Neioti Aiono Sailele Malielegaoi announced on Monday (2 December) that all branches of government, except water and electricity departments, will be closed on Thursday and Friday this week and civil servants will be redeployed to help in the mass immunisation drive to vaccinate everybody up to the age of 60 years.

The World Health Organization (WHO) estimates Samoa’s total population immunity to be as low as 31 per cent. To prevent measles outbreaks, it is recommended that countries should aim to achieve and sustain at least 95 per cent immunisation coverage.
