SAN FRANCISCO, Nov 12 (Reuters) - Nurses across the United States will stage protest rallies and strikes on Wednesday over what they say is insufficient protection for health workers dealing with patients possibly stricken with the deadly Ebola virus.

The California-based nurses' union, National Nurses United, says hospitals still lack enough hazardous materials suits which leave no skin exposed and sufficient powered air-purifying respirators to properly protect nurses from exposure.

"Inadequate preparedness for Ebola symbolizes the erosion of patient care standards generally," National Nurses United spokesman Charles Idelson said on Tuesday.

The U.S. Centers for Disease Control and Prevention says it has ordered $2.7 million worth of personal protective equipment to help hospitals care for Ebola patients.

National Nurses United expects some 100,000 nurses in more than a dozen U.S. states, in Washington DC and also in several other countries including Australia and the Philippines to take part in the day of action on Wednesday.

Most nurses in the campaign will not walk off the job but will hold rallies and demonstrations to bring the issue of inadequate Ebola protection to public attention, Idelson said. Some nurses will hold a vigil outside the White House.

The Ebola-related protests kicked off in the United States on Tuesday, when National Nurses United said nearly 20,000 nurses began a two-day strike in California. Their local union is also locked in acrimonious contract talks.

The Californian action targeted nearly 90 hospitals and clinics, mostly operated by Kaiser Permanente, the union said.

A Kaiser Permanente representative could not be reached for comment on Tuesday, but the organization has previously accused the union of using Ebola as a pretext to justify labor action.

The last U.S. patient being treated for Ebola recovered from the disease on Tuesday.
