there have been some reports over the years of clusters of cancer and other odd health concerns that seem to be clustered around HV transmission lines think 1MV+ however there was nothing proven conclusively.
There aren't many UHV power lines in the world and the few that exist are for very long hauls over uninhabited areas. Many 1MV projects got canned because it is harder to work with and low demand for 1MV components make them more expensive than what they might save.
Most long-haul lines today are still 700-850kV stepped down to 100-400kV before hitting urban power distribution rings. If there are HV lines going through your neighborhood, they are most likely ~300kV.
