How to say virus in Indonesian

Is the bird flu virus slumbering in Indonesian cats?

An Indonesian researcher has discovered that stray cats have antibodies to Java and Sumatra
Antibodies are also called immunoglobulins (Ig) and are proteins (glycoproteins) that the human body forms after contact with a foreign substance (antigen). These antibodies can then specifically bind to the antigens (in the so-called antigen-antibody reaction). The resulting immune complexes are then rendered harmless. Increased Ig levels generally indicate an increased immune defense, as often occurs in acute or chronic infectious diseases (allergic and parasitic diseases). The immunoglobulins are divided into four different classes (Ig A, Ig E, Ig G and Ig M). Depending on which type is more prevalent, this allows conclusions to be drawn about the disease in question.
against the causative agent of avian flu H5N1. If it turns out that the virus responsible is now more easily transmitted between cats than before, this could also pose a greater threat to the people living there.

Some of the stray domestic cats in Indonesia appear to have developed antibodies against the avian flu virus H5N1. This is reported by the science magazine New Scientist, although the findings of the scientist Chairul Anwar Nodom from Airlangga University in Surabaya, Java, have not yet been confirmed by other researchers. Nidom had examined more than 500 stray house cats in four different places in Java and Sumatra: 20 percent of the animals had H5N1 antibodies. "However, the detection of the antibodies does not automatically mean that the affected cats are still carrying these viruses in their bodies," explains Nidom. However, he fears that many other stray cats may already have fallen victim to the virus. Nobody can say how this number is high.

It is well known that the Spanish flu of 1918 was also due to a bird flu virus. Since these viruses have a high potential for change, it is feared that such a pandemic will occur again
A pandemic is a widespread disease that affects entire countries or continents.
If, for example, the genetic information of two different influenza viruses mixes in an intermediate host (e.g. pig), a new type of virus appears with as yet unknown properties. This so-called subtype can spread quickly because people do not have antibodies against this pathogen, either naturally or as a result of a vaccination. The annual influenza vaccination covers new variants of the influenza virus (i.e. slight changes in the surface structure), but not completely new subtypes. If a pandemic breaks out, a vaccine against the new subtype must therefore be developed quickly and / or an antiviral drug used across the board.
could come. As long as the virus does not spread from person to person, there is no risk of a pandemic, emphasizes the virologist Franz Xaver Heinz, head of the clinical institute for virology at the Medical University of Vienna. "In this respect it would be interesting to find out whether there was an infection between the cats", says Heinz. Since cats as mammals are more closely related to humans than birds, there would then be an increased risk that the circulating pathogens could now also be more easily transmitted between mammals and thus possibly also between humans. Nevertheless, experts like the Dutchman Albert Osterhaus from the Erasmus University in Rotterdam do not recommend hunting the cats in Indonesia in a targeted manner. On the other hand, it would make sense if you could prevent cats from eating infected birds. However, this poses a real challenge for the markets in Asia and Africa, especially since stray animals like to look for leftovers at the bird markets.
