Consider the following statement with respect to African swine fever : 1. It is a highly contagious and deadly viral disease in pigs. 2. It can affect both domestic and feral pigs. 3. It can cause fever and blood clotting in humans. Which of the statements given above are correct? Correct Answer 1 and 2 only

The correct answer is 1 and 2 only.

Key Points

  • African swine fever (ASF) : 
    • African swine fever is a highly contagious and deadly viral disease affecting both domestic and feral swine of all ages.
      • Hence statements 1 and 2 are correct.
    • ASF is not a threat to human health and cannot be transmitted from pigs to humans. It is not a food safety issue.
      • Hence statement 3 is incorrect.
    • ASF is found in countries around the world, particularly in sub-Saharan Africa. More recently, it has spread through China, Mongolia and Vietnam, as well as within parts of the European Union. 
    • The disease has a case fatality rate (CFR) of almost 100 per cent.
    • Its routes of transmission include direct contact with an infected or wild pig (alive or dead), indirect contact through ingestion of contaminated material such as food waste, feed or garbage, or through biological vectors such as ticks. 
    • The disease is characterized by sudden deaths in pigs. Other manifestations of the disease include high fever, depression, anorexia, loss of appetite, haemorrhages in the skin, vomiting and diarrhoea among others.
    • It is important that the determination of ASF is made through laboratory testing and it is differentiated from Classical Swine Fever (CSF), whose signs may be similar to ASF, but is caused by a different virus for which a vaccine exists. 
    • Even so, while ASF is lethal, it is less infectious than other animal diseases such as foot-and-mouth disease.
    • But as of now, there is no approved vaccine, which is also a reason why animals are culled to prevent the spread of infection.

Additional Information

  • Classical swine fever - 
    • Classical swine fever (CSF), also known as hog cholera, is a highly contagious multisystemic viral disease of swine that can run an acute, subacute, chronic, or late-onset course.
    • Swine can also be infected subclinically.
    • Domestic pigs, wild boar and feral pigs are the only animals susceptible to the classical swine fever virus (CSFV). 
    • Vaccination is available for CSF.

Fever in the season of dengue is sending Calcuttans scurrying to hospitals for admission, triggering a shortage of beds that has forced some private health care institutes to even postpone planned surgeries. Apollo Gleneagles Hospitals on the Bypass had 504 patients in its care as on Thursday of whom 70 had been admitted with fever. Belle Vue Clinic had 180 patients, 32 of them with dengue. Calcutta Medical Research Institute had 350 patients 60 of them with fever. The number of people admitted for treatment of fever caused by dengue or any undiagnosed illness has been rising every day across hospitals for more than a fortnight. "There has been heavy pressure on all private hospitals for admission of dengue and cases of unknown fever since the beginning of August. Now it is a surge," said Pradip Tondon, President of the Association of Hospitals of Eastern India. In July, four to five patients were getting admitted with fever on an average in every hospital. The number has since ballooned with the Calcutta Municipal Corporation apparently in denial about the extent of the dengue outbreak and the Government focused on playing down the threat. Such has been the rush of patients with fever that some hospitals are calling up people to postpone admissions planned in advance, mostly for surgeries. "We have told many people to come only when we call them to confirm availability of beds," said an official at Belle Vue.
The Government's "playing down the threat" means
