This potentially life-threatening virus is carried and transmitted by three types of ticks, including the deer tick that transmits Lyme disease.“About 15% of patients who are infected and have symptoms are not going survive,” said Lyons, who is also an assistant professor of neurology at Harvard Medical School. “Of the survivors, at least 50% will have long-term neurological damage that is not going to resolve.”
Just as there are no vaccines to prevent infection, there are also no treatments for Powassan. Scientists also believe Powassan is on the rise based on studies that have identified an increasing number of infections in deer.
“So it does seem that there are more and more deer that they’re finding that have been infected with this virus,” Lyons said. “So we should expect it to increase in human disease incidence over the next few years.”
Wolves hunt out the weak, the sick, the old, and the injured. They help the population of prey animals like the elk, deer, moose, and caribou, by taking away the weak and letting the strong survive. This is important part in the ecological system. By enhancing the strength into the herds. Without animals like the wolf to eliminate the weak, old , sick and injured, the herd of deer would swelter. They would become so numerous that they would starve to death. The wolf helps keep them healthy by insuring the breeding of the strong.
They help keep the forest clean by removing the sick before it can spread.Though no one can say how many infections will occur this year, warmer winters have led to an increased tick population, so experts predict rising tick-borne infections of many types.
