Pertussis, a highly contagious disease of the respiratory tract, is caused by exposure to bacteria (Bordetella pertussis) found in the mouth, nose and throat of an infected person. Pertussis is primarily spread by direct contact with discharge from the nose or throat of infected individuals. Classic - or severe pertussis - as defined by the World Health Organization, consists of at least 21 days of cough illness (with the cough coming in spasms or paroxysms), associated whoops or post-cough vomiting, and laboratory confirmation. Despite widespread vaccination, reports of pertussis continue to rise in the U.S. At particular risk are newborns and babies who have not yet been fully vaccinated against pertussis, who are more likely to have severe pertussis, and who face the possibility of serious complications and death. Over the last decade, 80% of pertussis deaths have occurred in infants under 6 months of age.
Approximately one-third of U.S. children were undervaccinated for more than six months and one-fourth experienced delays in receiving many of the recommended vaccinations during their first 24 months of life, according to a study in the current issue of JAMA.
As global health leaders struggle to meet the United Nations goal of reducing mortality among the world's poorest children, vaccines are attracting more and more attention. The purchase of the vaccine is just the beginning, however, as the effectiveness of a vaccine is only as good as its delivery system.
Experts are recommending that adolescents and some adults be vaccinated against whooping cough to help prevent infection and potential transmission to infants, according to the December 15 issue of Clinical Infectious Diseases, now available online.
To stick to cells in the respiratory tract and start an infection, the bacterium Haemophilus influenza has to secrete a glue-like protein. Researchers at Washington University School of Medicine in St. Louis report this week that a study of the valve that lets out the glue has produced some surprising information.
The Ministry of Health's Dr Alison Roberts says "Numbers have been on the rise since June this year, but they really spiked up in August. We have been expecting an epidemic around now.
Western Australia is experiencing the highest level of whooping cough (pertussis) notifications since 1997, when more than 1200 cases were notified.
Pertussis is a contagious illness caused by bacteria. It occurs in infants and young children more often than older children and adults. Adults with milder, undiagnosed symptoms can transmit the disease to infants and children.
Little is known about the causes of lymphoma. A case-control study conducted by Professor Nikolaus Becker and Dr. Alexandra Nieters, Division of Clinical Epidemiology at the Deutsches Krebsforschungszentrum (German Cancer Research Center, DKFZ), is looking closely at possible risk factors.
From the end of September these vaccines will be given in the routine vaccination schedule in a combined vaccine along with Diphtheria, Tetanus, and Hib.
The British government has announced plans for a new combined vaccination for babies and children. A single jab will protect children against diphtheria, tetanus, pertussis (whooping cough), Haemophilus influenzae type B (Hib), and polio.
The U. S. Department of Health and Human Services has announced that the nation's childhood immunization rates are at record high levels, including significant increases in rates of immunization for chickenpox and pneumococcal pneumonia, the two most recent additions to the childhood immunization schedule.
As a precautionary measure, Swedish Medical Center is expanding its investigation of possible exposures to the pertussis (whooping cough) bacteria to include additional patients and employees.
More than 20 percent of preschool children lack required immunizations, placing them and their classmates at risk for illness, according to a new study based on the federal National Immunization Survey.
Dr. Eric E. Whitaker, state public health director, today urged parents to ensure their children have been properly immunized against this highly contagious disease and asked that persons exhibiting symptoms to immediately seek medical care.
Health-care providers can now review and update immunization records for patients online using the new and improved Web-based CHILD Profile Immunization Registry. The system is operated by the Department of Health and makes it easier for health-care professionals to keep track of immunization records.
Despite spending more for health care, Americans do not have the best medical care in the world, according to researchers from the Johns Hopkins Bloomberg School of Public Health and other institutions.
Immunization for pertussis, also known as whooping cough, began in the mid-1940s and resulted in a sharp decline of this serious illness over the next 25 years. Over the last two decades, however, as immunity has waned, pertussis has re-emerged in the United States, with the greatest increase seen in adolescents, adults and young infants.
Reports from the countries say that the immunization campaign has reached some of the most remote areas, including border regions and indigenous communities. The reports also show that the vaccination efforts, which began April 24, are reaching the most vulnerable sectors of the population.
A quarter century ago, the Pan American Health Organization (PAHO) and its member countries launched a unique procurement and financing mechanism to buy vaccines, syringes, and "cold chain" equipment – the basic components of their immunization programs.
Parents who may be concerned by a scare over the side effects of the whooping cough vaccine will be reassured by a new study involving thousands of children. The Department of Health advice that babies should be vaccinated against whooping cough (pertussis) at the age of two, three and four months has been questioned by some scientists who have suggested a link with asthma and allergies.
