New Common Cold Virus Variant Deadly

November 26, 2007 | by

Last week, the Centers for Disease Control and Prevention (CDC) reported that a new virulent strain of the common cold virus, adenovirus, has caused 10 deaths over the last 18 months [1]. The virus, identified as adenovirus serotype 14 (Ad14), is a rarely reported strain of adenovirus that can cause severe and even fatal respiratory illness. It’s unusual since adenoviruses typically cause non-lethal infections. According the the CDC report:

The cases described in this report are unusual because they suggest the emergence of a new and virulent Ad14 variant that has spread within the United States.

Indeed, between the months of March-June 2007, Ad14 caused at least 140 respiratory illnesses in three states; Oregon, Texas and Washington [1]. More than 50 of those patients were hospitalized, including 24 who were admitted to intensive care units. Nine of those patients died, most from severe pneumonia. People of all ages have been affected, including healthy young adults, typically the group least susceptible.

The Flu, Your Health and the Importance of Vaccination

November 1, 2007 | by

The flu season runs from November to April, with most cases occurring between late December and early March. About 10% to 20% of people get the flu every winter [1]. In children, the odds are even worse, with up to 40% of children becoming clinically ill due to the influenza virus.

The best way to prevent seasonal flu is to get a flu vaccination. Hospitalization and death from flu complications pose real risks. Every year, on average, more than 200,000 people are hospitalized from flu complications and approximately 36,000 people die from the flu [2].

Additionally, immunizing children against influenza is perhaps the best method to reduce the occurrence of the flu in the community. If children receive the flu shot but the rest of the family abstains, the influenza attack rate drops by 40%; if parents also get the flu shot, the influenza attack rate drops by 80% [3].

Top 10 Places Cold and Flu Germs Hide

Cold and flu germs hide everywhere and while most of us love surprises, suddenly coming down with the cold or flu isn’t one of them. Keeping your hands clean goes a long way towards preventing illness. In addition to that, here’s some tips on the places where cold and flu germs hide and the precautions you can take to stay healthy.

The Best Way to Stay Healthy and Avoid Getting Sick

The best way to stay healthy and avoid getting sick is to wash your hands. Some of the most recent scientific evidence comes from a study of hospital-acquired methicillin-resistant Staphylococcus aureus infection. Methicillin-resistant Staphylococcus aureus (MRSA or “staph”) is a bacteria that can enter the body through breaks in the skin and cause severe infections and even death, especially in people who are already sick. MRSA represents a major control problem in hospitals as it has developed a resistance to all penicillins, including methicillin and other narrow-spectrum beta-lactamase-resistant penicillin antibiotics [1]. Researchers concluded at the end of the study that hospitals could greatly limit the spread of MRSA through the use of increased barrier protection (gloves) by workers and more frequent hand washing [2].

Sinus Congestion

The sinuses are hollow spaces located inside the bones in the skull to either side of the nose, behind and in between the eyes, in the forehead and at the back of the nasal cavity. The sinuses are lined with a moist, thin layer of tissue called a mucous membrane, which not only humidifies the air as you breathe it in, but also produces mucus to trap irritants such as dust, pollen and bacteria. The sinuses are lined with microscopic hairs called cilia. The function of cilia is to move mucus to flush the sinuses and nasal passageways of trapped irritants.

Sinus congestion is the blockage of one or more of the nasal passageways as a result of inflammation and swelling of the sinus tissues, secretion of mucus or a deviated septum (meaning obstruction of the nasal passage by the membranous ridge of cartilage in the nose that separates the nasal cavity into the two nostrils). Sinus congestion leads to impaired flow of mucus out of the sinuses. The build up of mucus in the sinuses causes increased pressure. Also, bacteria can become trapped and infect the mucous membrane, a condition termed sinusitis.
