Guarding Against Pneumococcal Disease: The Power of Vaccination
The Threat of Pneumococcal Disease
Pneumococcal disease, caused by the bacterium Streptococcus pneumoniae, is a significant global health concern. This bacterium is capable of causing a wide range of infections, from mild conditions such as sinusitis and otitis to severe diseases including pneumonia, Sepsis, and meningitis.
Although these infections can be treated with antibiotics, the effectiveness of such treatments is not always guaranteed, making prevention via vaccination crucial. The threat is particularly concerning during the cold season when the risk of bacterial infections is higher. Furthermore, pneumococcal disease can be severe, leading to complications and long-term hospitalization. This makes it imperative to take preventive measures, particularly for those with weakened immune systems.
Transmission and Risk Factors
Streptococcus pneumoniae is spread from person to person through droplets in the air, usually when an infected person coughs or sneezes. Many people, especially children, carry the bacteria in their nose and throat without getting sick, but they can still spread the bacteria to others.
While anyone can get pneumococcal disease, certain groups are at higher risk. These include babies, children under five years old, adults 65 years and older, and people with weakened immune systems due to conditions like asthma, sickle cell disease, HIV infection, or diabetes. Pneumococcal disease is also more likely to become invasive in some people, spreading to normally sterile parts of the body like the blood, spinal fluid, and brain.
The Burden of Pneumococcal Disease
Pneumococcal pneumonia alone hospitalizes about 150,000 people in the US each year, with about 5-7 percent of those infected succumbing to the disease. The death rate is even higher among adults aged 65 years and older and people with certain medical conditions or other risk factors.
While fewer adults contract pneumococcal meningitis or bloodstream infection, the mortality rate for these infections is higher, killing more than 3,000 US adults each year even with proper treatment. Pneumococcal meningitis and bacteremia can also result in lifelong disability, including deafness, brain damage, and limb amputation.
Symptoms of Pneumococcal Disease
Symptoms of pneumococcal disease depend on the part of the body affected. These may include a combination of high fever, chills, cough, shortness of breath, chest pain, stiff neck, disorientation, and sensitivity to light. Early diagnosis and treatment are crucial for serious pneumococcal infections.
Vaccination: The Best Preventive Measure
The most effective way to protect against pneumococcal disease is through vaccination. Vaccines recommended include the pneumococcal conjugate vaccine (PCV13, PCV15, PCV20) and the pneumococcal polysaccharide vaccine (PPSV23). The type and timing of the vaccine depend on the age and risk group of the individual.
Notably, vaccination not only protects the vaccinated individual but also reduces the spread of pneumococcus among families and community members by reducing the amount of bacteria in the vaccinated person’s nose.
The Importance of Vaccination during Flu Season
Having influenza increases the risk of getting pneumococcal disease, making protection against pneumococcal disease especially important during flu season. Both vaccines can be administered during one healthcare visit for both children and adults, but they should be given at two different injection sites.
Antibiotics and Pneumococcal Disease
While antibiotics are used to treat pneumococcal disease, it’s important to note that in nearly one-third of cases, pneumococcal bacteria can be resistant to treatment with one or more antibiotics. This further highlights the crucial role of vaccination in preventing the disease.
With the threat of pneumococcal disease looming, especially during the cold season, it is crucial that everyone, particularly those at high risk, take preventive measures. The pneumococcal vaccine is a powerful tool in this regard, helping to reduce the risk of severe infection, complications, hospitalization, and even death. It is an effective way to guard against such bacteria and maintain public health.
