Ilmuwan Australia Identifikasi Virus Baru dari Kelelawar

Jakarta – Para peneliti dari Commonwealth Scientific and Industrial Research Organisation (CSIRO), badan sains nasional Australia, berhasil mengidentifikasi jenis virus baru yang diisolasi dari kelelawar terbang. Temuan ini dinilai dapat memperkuat sistem kewaspadaan dini negara itu dalam menghadapi ancaman penyakit infeksius di masa depan.

Virus yang dinamai Salt Gully virus itu berhasil diambil dari sampel urine kelelawar di Queensland. Proses isolasi dan kultivasi dilakukan di laboratorium berstandar tinggi milik CSIRO, Australian Centre for Disease Preparedness (ACDP), yang dirancang khusus untuk menangani patogen berbahaya.

Salt Gully virus termasuk dalam keluarga yang sama dengan dua virus mematikan: Hendra virus—yang dapat menyebabkan infeksi fatal pada kuda dan manusia di Australia—dan Nipah virus—pemicu sejumlah wabah serius pada manusia di Asia.

Menurut Jennifer Barr, ilmuwan eksperimental di ACDP CSIRO, kelompok henipavirus telah ditetapkan Organisasi Kesehatan Dunia (WHO) sebagai patogen prioritas untuk penelitian lebih lanjut. “Penemuan ini memberikan pemahaman baru yang penting tentang keragaman dan evolusi virus dalam kelompok berisiko tinggi tersebut,” ujarnya.

Meski demikian, Barr menekankan bahwa masyarakat tidak perlu khawatir berlebihan. “Virus Salt Gully bukan hal yang benar-benar baru di alam. Kami telah mendeteksinya dalam sampel yang disimpan sejak 2011, yang menunjukkan bahwa virus ini telah ada setidaknya lebih dari satu dekade tanpa ada indikasi bahwa ia menyebabkan penyakit pada hewan atau manusia,” jelas Barr.

Potensi Wabah dan Kesiapan Deteksi

Para peneliti masih melakukan kajian mendalam untuk membandingkan karakter Salt Gully virus dengan Hendra dan Nipah, termasuk kemungkinan daya patogenitasnya.

“Temuan awal kami menunjukkan bahwa Salt Gully virus tidak menggunakan reseptor sel inang yang sama dengan Hendra atau Nipah. Artinya, mekanisme infeksinya mungkin berbeda. Karena itu, terlalu dini untuk memprediksi apakah virus ini berpotensi menyebabkan wabah pada manusia atau hewan di masa depan,” papar Barr.

Keberhasilan mengidentifikasi virus ini memungkinkan pengembangan alat diagnostik yang spesifik. “Jika suatu saat virus ini muncul dan menyebabkan wabah, kita sudah memiliki tes deteksi yang siap digunakan. Ini adalah langkah penting untuk merespons lebih cepat dan mencegah penyebaran,” tambahnya.

Vaksin Hendra yang selama ini digunakan untuk melindungi kuda tetap efektif, dan temuan virus baru ini tidak mengubah rekomendasi perlindungan yang sudah ada.

Fasilitas ACDP memegang peran kunci dalam kesiapan Australia menghadapi wabah penyakit, dengan keamanan mikrobiologis dan fisik yang ketat sehingga memungkinkan penelitian terhadap patogen berbahaya tanpa risiko kebocoran.

Studi ini telah dipublikasikan dalam jurnal Emerging Infectious Diseases edisi September, menandai kontribusi penting dalam pemantauan virus-virus liar yang berpotensi menjadi ancaman kesehatan global.

Global Health Challenges: Examining the Impacts of Infectious Diseases

samudrapost — Tue, 28 Mar 2023 08:55:44 +0000

Global health challenges have increased in recent years, with infectious diseases and climate change being two of the most significant issues affecting health outcomes worldwide. Both of these challenges have significant consequences on human health, and addressing them requires a global response that prioritizes prevention and intervention.

Infectious diseases such as malaria, tuberculosis, and HIV/AIDS are major contributors to the global disease burden, particularly in low- and middle-income countries. These diseases disproportionately affect vulnerable populations, including children, the elderly, and people living in poverty. The COVID-19 pandemic has brought global attention to the importance of pandemic preparedness and the need for robust public health systems to respond to outbreaks.

Climate change also has significant implications for global health. Rising temperatures, changing precipitation patterns, and extreme weather events are leading to increased risks of food and water insecurity, malnutrition, and infectious diseases. The impacts of climate change on health are not limited to developing countries, as more frequent and severe weather events can also affect infrastructure and healthcare delivery in developed countries.

Addressing these global health challenges requires a coordinated effort at the global, national, and local levels. Strategies such as disease surveillance, prevention, and control, vaccine development, and investing in health systems can help prevent the spread of infectious diseases. Mitigating climate change requires reducing greenhouse gas emissions, transitioning to renewable energy sources, and promoting sustainable land use practices.

A key element of addressing these challenges is building strong partnerships and collaborations across sectors, including healthcare, government, academia, and civil society. This includes engaging communities in planning and implementing solutions that are culturally appropriate and address their specific health needs.

In conclusion, global health challenges such as infectious diseases and climate change require a sustained and coordinated effort at the global, national, and local levels. By investing in prevention and intervention strategies, building strong partnerships, and engaging communities, we can work towards a healthier and more sustainable future for all.
