Why in News
Nagaland has not reported fresh cases of African Swine Flu in the last two weeks.
- The disease was first reported in November-December, 2019 from the areas of China bordering Arunachal Pradesh.
- Earlier in April 2020, there were reported deaths of pigs due to the Classical Swine Fever (CSF).
- It is a highly contagious and fatal animal disease that infects and leads to an acute form of hemorrhagic fever in domestic and wild pigs.
- Other manifestations of the disease include high fever, depression, anorexia, loss of appetite, hemorrhages in the skin, vomiting and diarrhoea among others.
- It was first detected in Africa in the 1920s.
- Historically, outbreaks have been reported in Africa and parts of Europe, South America, and the Caribbean.
- However, more recently (since 2007), the disease has been reported in multiple countries across Africa, Asia and Europe, in both domestic and wild pigs.
- The mortality is close to 100% and since the fever has no cure, the only way to stop its spread is by culling the animals.
- ASF is not a threat to human beings since it only spreads from animals to other animals.
- ASF is a disease listed in the World Organisation for Animal Health (OIE) Terrestrial Animal Health Code and thus, reported to the OIE.
- Classical Swine Fever:
- CSF, also known as hog cholera, is an important disease of pigs.
- It is one of the most economically-damaging pandemic viral diseases of pigs in the world.
- It is caused by a virus of the genus Pestivirus of the family Flaviviridae, which is closely related to the viruses that cause bovine viral diarrhoea in cattle and border disease in sheep.
- Mortality is 100%.
- Recently, the ICAR-IVRI developed a Cell Culture CSF Vaccine (live attenuated) using the Lapinized Vaccine Virus from foreign strain.
- The new vaccine has been found to induce protective immunity from day 14 of the Vaccination till 18 Months.
