Explainer: Low vaccination rates, global outbreaks fuel U.S. measles spread

(Reuters) – A measles outbreak that has stricken at least 225 people in New York state since October began with a traveler who visited Israel during the Jewish high holidays and returned to a predominantly ultra-Orthodox Jewish neighborhood of Rockland County.

A similar pattern unfolded three months later and nearly 3,000 miles (4,800 km) away when a person who visited Eastern Europe returned to a community with strong ties to a local church group in Vancouver, Washington. More than 50 people fell ill there.

In both instances, U.S. travelers picked up measles in foreign countries where the highly contagious disease was running rampant and brought it back to places where vaccination rates were too low by U.S. public health standards, setting off the worst outbreaks seen in those states in decades.

The U.S. Centers for Disease Control and Prevention says New York’s outbreak marks the highest tally of imported cases since measles was declared eradicated in the United States in 2000.

The two outbreaks appear to be winding down, health officials say, after concerted efforts to pinpoint the origins and isolate and inoculate those who were exposed but unprotected and educate parents who had resisted vaccines.

The disease has spread mostly among school-age children whose parents declined to get them vaccinated. Most cited philosophical or religious reasons, or concerns – debunked by medical science – that the three-way vaccines against measles, mumps and rubella (MMR) could cause autism, authorities said.

New York State Health Commissioner Dr. Howard Zucker said another key factor was mere “complacency” in an age where the potential ravages of measles are unfamiliar to parents who came of age after the vaccine was introduced in 1957.

In Rockland County, the suburb north of Manhattan accounting for the bulk of cases, the state has vaccinated 15,000 children since the outbreak began there last autumn, Zucker said. The Brooklyn borough of New York City was another hot spot.

Still, officials say the measles crisis in New York and Washington states offer a lesson about the importance of maintaining a minimum level of “herd” immunization against dangerous, preventable diseases such as measles.

It also highlights the global nature of disease control, in which a hot spot of infection in one country can ignite a distant outbreak in an immunization-weak spot of another, said Dr. Scott Lindquist, Washington’s top epidemiologist.

Here are some key facts about measles and immunization, according to public health experts and the CDC.

WHAT IMMUNIZATION RATES ARE IDEAL?

A 95 percent rate of immunization is required to provide sufficient “herd” protection in a given population. Rates as low as 60 percent were found in parts of New York where measles spread, Zucker said.

HOW BAD CAN MEASLES GET?

Symptoms typically include high fever, cough, runny nose and watery eyes, followed by tiny white spots inside the mouth and a red rash that can cover the body.

Serious and potentially fatal complications, especially in young children and pregnant women, can include pneumonia and swelling of the brain. Ear infections occur in about 10 percent of children with measles and can lead to permanent hearing loss.

One rare but fatal complication is subacute panencephalitis (SSPE), which can attack the central nervous system seven to 10 years after a person has recovered from measles.

HOW CONTAGIOUS IS MEASLES?

Measles is spread through casual contact with the virus, which can linger and remain infectious in the air of an enclosed space for up to two hours after it is breathed out by someone carrying the disease. The rate of transmission from an infected person to another individual nearby who lacks immunity is about 90 percent.

ORIGINS OF LATEST OUTBREAKS?

Health authorities say the strain of the virus identified in Washington state matches the one circulating widely in Ukraine since last year. The New York outbreak has been tracked back to separate flare-ups of measles in Israel and in Eastern Europe.

DOH vaccination activity vs measles, rubella, polio extends until March 7

Aileen Cerrudo   •   March 4, 2021

MANILA, Philippines—The Department of Health (DOH) has extended the Measles, Rubella, and Oral Polio Vaccine Supplemental Immunization Activity (MR-OPV SIA) until March 7.

The health department said this is in order to reach the target population of 95%.

As of March 1, 2021, the health department reported that of the national target, 83.7% or 4,269,423 have been vaccinated against Measles and Rubella; while 3,939,677 or 82.4% have been vaccinated against Polio.

The extension of the immunization program aims to vaccinate over 800,000 more children in the target regions in the country.

Health Secretary Francisco Duque III encourages parents and legal guardians to have their 0-59 month old children vaccinated against vaccine-preventable diseases under the MR-OPV SIA.

“To our parents and guardians, let us retain our confidence in vaccines and put our trust in science. These vaccines are proven safe and effective. Let us protect our children and not deny them the opportunity to grow into healthy individuals, free from vaccine-preventable illnesses,” he said. -AAC

Manila Health Department finishes over 80% measles vaccination in 9 days

Aileen Cerrudo   •   February 12, 2021

MANILA, Philippines—The Manila Health Department (MHD) successfully finished over 81.6% of the Measles-Rubella Supplemental Immunization Activity in the City of Manila.

MHD began the vaccination activity on February 1 and based on the latest report, 14,936 children in the city were vaccinated in a span of 9 days.

Manila City Health Officer Dr. Arnold Pangan said the MHD aims to complete the program before the city begins its vaccine rollout for the coronavirus disease (COVID-19).

“We targeted na matapos talaga agad itong measles vaccination para mas makapaghanda rin ang Manila Health Department sa oras na magsimula na tayo sa mass COVID-19 vaccination dito sa Manila,” he said.

He added that the measles vaccination is also helpful for medical frontliners to prepare and familiarize themselves with the city’s vaccination process.

The Manila Public Information Office (MPIO) said the program to vaccinate children against measles is implemented nationwide through coordination between the Department of Health (DOH), World Health Organization (WHO), UNICEF, RELIEF International, Healthy Philippines, and local government units across the country.

Dr. Pangan further stated that the MHD is ready to vaccinate the remaining 25,890 children in the city by next week. AAC

MANILA, Philippines—The phase 2 of the nationwide Measles Rubella and Oral Polio Vaccine Supplemental Immunization Activity (MR-OPV SIA) began on Monday (February 1), according to the Department of Health (DOH).

The DOH, all local government units (LGUs), and other partners of the vaccination campaign will conduct Phase 2 in the Visayas Regions, National Capital Region, Central Luzon and CALABARZON.

The health department, in a statement, said Phase 2 aims to vaccinate 5.1 million 9-59 months old children for the Measles Rubella (MR) vaccine and 4.8 million children 0-59 months old for Oral Polio vaccine (OPV).

The DOH also reported that aside from the coronavirus disease (COVID-19) pandemic, the country is also facing polio, and measles outbreak.

World Health Organization – Philippines Representative Dr. Rabindra Abeyasinghe assured that the WHO will assist the health department and local government units to ensure that every child in the Philippines is vaccinated.

“We can only halt an impending measles outbreak and stop the spread of polio if we vaccinate every eligible child. This is challenging but is necessary for the protection of our children,” Abeyashinghe said. AAC
