By TELEMUNDO PR • 42 mins ago • Updated 42 mins ago

The Department of Health confirmed on Thursday that the H5N1 avian influenza was detected in chickens on the island municipality of Culebra.

According to the newly appointed Secretary of Health, Victor Ramos, a multidisciplinary team of experts has taken immediate action to address this situation as a priority, and he assured that so far it is under control and under surveillance.

"No cases of infection in humans have been reported, and epidemiological surveillance systems, including wastewater monitoring, have not detected evidence of the virus outside of the affected birds in the region," Ramos said in a written statement.

The secretary led a rapid action committee and traveled to Culebra, where he met with the mayor of the island municipality and made visits to the ranch where the outbreak was detected, as well as to the Diagnostic and Treatment Center (CDT).​

WASHINGTON, January 13, 2025 – The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic avian influenza (HPAI) in a backyard poultry flock in Puerto Rico. This is the first case of HPAI in domestic birds in Puerto Rico during this outbreak, which began in February 2022.

Samples from the flock were tested and confirmed at the APHIS National Veterinary Services Laboratories in Ames, Iowa.

APHIS is working closely with animal health officials in Puerto Rico on a joint incident response and will provide appropriate support as requested.

According to the U.S. Centers for Disease Control and Prevention (CDC), the public health risk associated with these avian influenza detections in birds remains low. As a reminder, the proper handling and cooking of all poultry and eggs to an internal temperature of 165˚F is recommended as a general food safety precaution.

As part of existing avian influenza response plans, APHIS and the Puerto Rico Department of Agriculture are conducting additional surveillance and testing in areas around the affected flock. The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.

Anyone involved with poultry production from the small backyard to the large commercial producer should review their biosecurity activities to assure the health of their birds. Visit APHIS’ Defend the Flock Resource Center for materials about biosecurity, including videos, checklists, and a toolkit.

USDA will report these findings to the World Organisation for Animal Health (WOAH) as well as international trading partners. USDA also continues to communicate with trading partners to encourage adherence to WOAH standards and minimize trade impacts. WOAH trade guidelines call on countries to base trade restrictions on sound science and, whenever possible, limit restrictions to those animals and animal products within a defined region that pose a risk of spreading disease of concern. WOAH trade guidelines also call on member countries to not impose bans on the international trade of poultry commodities in response to notifications in non-poultry.

All cases in commercial and backyard flocks are listed on the APHIS website.

In addition to practicing good biosecurity, all bird owners should prevent contact between their birds and wild birds and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through APHIS’ toll-free number at 1-866-536-7593. APHIS urges producers to consider bringing birds indoors, when possible, to further prevent exposures. The Animal Health Protection Act authorizes APHIS to provide indemnity payments to producers for birds and eggs that must be depopulated during a disease response. APHIS also provides compensation for disposal activities and virus elimination activities. Additional information on biosecurity for backyard flocks can be found on APHIS’ Defend the Flock webpage. Additional background Avian influenza (AI) is caused by an influenza type A virus which can infect poultry (such as chickens, turkeys, pheasants, quail, domestic ducks, geese, and guinea fowl) and is carried by free flying waterfowl such as ducks, geese and shorebirds. AI viruses are classified by a combination of two groups of proteins: hemagglutinin or “H” proteins, of which there are 16 (H1–H16), and neuraminidase or “N” proteins, of which there are 9 (N1–N9). Many different combinations of “H” and “N” proteins are possible. Each combination is considered a different subtype and can be further broken down into different strains which circulate within flyways/geographic regions. AI viruses are further classified by their pathogenicity (low or high)—the ability of a particular virus strain to produce disease in domestic poultry.

27 people under surveillance after cases of avian flu were detected in Lajas and Cabo Rojo

Health Secretary Victor Ramos emphasized, however, that the probability of person-to-person transmission is very low.

Following the detection of avian flu cases in Lajas and Cabo Rojo , Agriculture Secretary Irving Rodriguez Torres indicated this Tuesday that they are focusing on establishing precautionary measures to prevent further infections that threaten the poultry industry, while the Department of Health is monitoring approximately 27 people who were on the two affected private farms.

“The concern is total,” the Secretary of Agriculture stated at the bi-weekly press conference “On Record,” at the Red Palace of La Fortaleza.

“ For us in the agricultural sector, it’s very worrying because if one of these birds were to arrive at a ranch, or if there were a large number of them, we would have to eliminate them all. That’s a concern for us, specifically in the poultry sector. So, preventing potential economic losses is a priority. We have direct communication with the largest producers and the biggest private companies,” Rodríguez Torres added.

The Department of Agriculture confirmed the deaths of 20 Creole ducks, 30 guinea fowl, and other bird species in Cabo Rojo and Lajas due to a diagnosis of highly pathogenic avian influenza (HPAI) after conducting the necessary tests. The secretary confirmed that these are not commercial locations, but rather private farms.

“We must be careful with wild animals that may reach these facilities. This is an issue that concerns each individual, and we must reinforce sanitary practices ,” he stressed.

He mentioned that, at the moment, it is suspected that the avian flu may have been transmitted by “migratory birds.” “We know that ducks, specifically, migrate practically all over the planet, and since that was the species we found there, well, that is our first focus,” the secretary commented.

He urged citizens and poultry farmers to report any abnormalities they observe – such as high mortality rates or birds with general weakness – to the Animal and Plant Health Inspection Service of the federal Department of Agriculture (USDA) at 1-866-536-7593 or to the Puerto Rico Department of Agriculture at 787-721-2120.

“It is of utmost importance for us to protect the poultry sector in Puerto Rico, both eggs and meat, so that we can avoid economic losses and, above all, maintain the stability of the sector ,” said Rodríguez Torres.

27 people exposed are being monitored

For his part, the Secretary of Health, Víctor Ramos Otero , confirmed that they are keeping 27 people under surveillance who were on the two affected private farms in the south, and assured that they are prepared to handle this emergency.


Avian flu can be transmitted to people through direct contact with infected animals, their secretions (feces, saliva or mucus) or contaminated surfaces, but the Health Minister stressed that this contagion “is very low” .

“We have established epidemiological surveillance of all contacts at the two locations where the incidents occurred,” he stated. “So far, no one has developed symptoms.”

“The reality is that the treatment is no different from the treatment of any other influenza, so we treat thousands of cases of influenza a year; what is different is the source and what type of influenza it is, but the treatment is the same ,” Ramos Otero added.

Regarding the symptoms, he said that "they are the same as any type of influenza," and include fever, difficulty breathing, body aches, muscle pain, and even vomiting and diarrhea.

“That’s why I say that even if they have symptoms and have been in contact with someone, what they probably have is human influenza and not avian influenza . But we have the means to take a sample if it becomes necessary to test someone,” he stated.

Implements 120-day quarantines,
other measures


By THE STAR STAFF

Agriculture Secretary Irving Rodríguez Torres announced on Tuesday the implementation of 120-day quarantines, along with biosecurity, epidemiological surveillance and sanitary control measures, after several birds in the municipalities of Cabo Rojo and Lajas tested positive for avian influenza, or bird flu.

“From the very beginning, we have acted proactively and in coordination with federal authorities. Now that we have laboratory results confirming the presence of the virus, we are reinforcing surveillance, biosecurity, and control measures to prevent its spread,” the secretary stated in a written release. “Our priority is to protect the health of our birds, support our producers, and safeguard the stability of Puerto Rico’s poultry industry.”

Investigations began following reports of multiple bird deaths at two properties in Cabo Rojo and Lajas. At the first location, the deaths of some 20 Muscovy ducks were documented, while the second location reported mortality among various species, including about 30 guinea fowl.

The measures include controls on the entry and exit of authorized personnel; disinfection of footwear, equipment, vehicles and materials; and periodic visits to assess sanitary conditions, monitor mortality rates and determine if further action is required.

The handling and disposal of dead birds will be carried out in accordance with the instructions of competent authorities. Likewise, any further decisions regarding surviving birds will be subject to epidemiological assessments and veterinary recommendations.

The agriculture secretary emphasized that a key priority is preventing the virus from reaching commercial poultry facilities or backyard flocks, as an outbreak could result in economic losses for producers, increased operational costs and potential additional restrictions on the movement of birds.

“We are in direct communication with regional producers and poultry industry representatives to reinforce prevention measures,” Rodríguez Torres stated. “We recognize the importance of this sector to our agricultural output, so we will remain vigilant for any signs that could pose a risk to our farms. Early detection and adherence to sanitary protocols are crucial to protecting our farmers.”

As part of prevention efforts, special attention will also be paid to interactions between wild birds and domestic or commercial poultry. Although the potential role of migratory birds is being assessed, authorities clarified that the specific origin of the cases has not yet been established; therefore, epidemiological investigations will continue.

While the risk of avian influenza infection for the general public is considered low, authorities noted that individuals who have direct contact with infected birds or contaminated environments may face a higher risk.

For this reason, the public is urged to avoid touching, collecting, or moving sick or dead birds, and to refrain from handling them without proper guidance and protective measures.

Farmers, poultry producers, backyard flock owners, and the general public are asked to immediately report any instances of unusual mortality among domestic or wild birds.

Preventive recommendations include keeping domestic birds separate from wild birds, enhancing the cleaning and disinfection of facilities, limiting access to rearing areas by unauthorized persons, and promptly reporting any signs of illness or sudden increases in mortality.

Sick birds or multiple deaths can be reported by contacting USDA-APHIS at 1-866-536-7593. Guidance is available from the Puerto Rico Department of Agriculture at 787-721-2120.
