Dear Patients:
In an effort to minimize the risk of spreading coronavirus to the public and to those who are at high risk, we are screening patients who call for an appointment to see if they have any symptoms consistent with COVID-19 or if they may have any known exposure.  If they do, we have instituted the following temporary policy: 
  • We WILL NOT be seeing patients with cold/upper respiratory symptoms in the Office unless we determine they are not infected.  
  • We will arrange for a Telehealth/Virtual visit with the Doctor using Doximity or phone visit for these patients.
  • All patients must have a face covering.
Please be assured we will be there to answer any questions or to determine if you need to be tested.

Please DO NOT enter the office if you have any symptoms.
​​​​​​​We appreciate your support and want to thank you all for allowing us to do remote visits with you.  We plan to remain open and to continue to see patients for other acute non-infectious problems. We are following the guidelines instituted by the Oakland County Health Department, which include screening and taking temperatures of all our employees on a daily basis, ensuring social distancing is maintained, increased cleaning and disinfecting of our office, and requiring both patients and employees use face coverings in the office.

If you are over the age of 65, and do not feel  comfortable coming into the office, we recommend that you book a video visit or phone call.  Please call the office to see if you qualify for a visit and to schedule an appointment.

We understand that this is a worrisome time especially if you are exhibiting symptoms, but as medical practitioners we also have an obligation to protect our community and other patients.  In the meantime, we ask that you follow CDC recommended guidelines (see below)  for hand washing and sanitizing.  Stay away from others, especially if you are over 65, have a chronic medical condition or if you have any symptoms.

We thank you for your cooperation and for patience as we navigate this crisis.  We want you to know that we care for the health of all our patient's and will do our best to do whatever we can for you during these trying times.  We feel very fortunate to be able to take care of you. 
Again, we thank you for your support.  May you and your loved ones stay healthy and safe,
Dr. Bering & Dr. Weiermiller & Staff

Three Important Ways to Slow the Spread

As COVID-19 continues to spread across the country and the world, we all must remain vigilant. The changes we have had to make to routines and daily life are extremely hard, but these changes are even more important now and in the future. We must stop the spread of this new and dangerous virus. The more steps you and your family can take to prevent the spread of COVID-19, the safer you will be.

hands washing and hands using hand sanitizer
How to Protect Yourself When Going Out
  • Wear a mask that covers your nose and mouth to help protect others.
    • Choose a mask with two or more layers of washable, breathable fabric that fits snugly against the sides of your face.
  • Stay 6 feet apart and avoid crowds.
    • The more people you are in contact with, the more likely you are to be exposed to COVID-19.
  • Avoid indoor spaces as much as possible, particularly ones that aren’t well ventilated.
    • You may find it harder to stay 6 feet apart in indoor spaces.
  • Wash your hands often.
    • Use soap and water for 20 seconds, especially after you have been in a public place or hand sanitizer if soap and water aren’t available.

As the new coronavirus, COVID-19, continues to evolve, Beaumont Health is taking multiple steps to help reduce the spread of the disease.

  • Visitor safety restrictions to be put in place at all eight Beaumont hospitals.
  • Beaumont Health has launched a Coronavirus Hotline:

Beaumont's hotline is staffed by Beaumont nurses and staff seven days a week. The hotline is a community resource for timely, accurate information about COVID-19 symptoms and virtual screening for people who are experiencing symptoms. The line is open from 8 a.m. to 5 p.m. Monday through Friday. 

​​​​​​​For general information about coronavirus/COVID-19 and how to stay healthy during this evolving situation, please go to   https://www.beaumont.org/health-wellness/coronavirus

Please do not call the hotline unless you or a loved one is experiencing symptoms such as fever, cough and shortness of breath. If you are experiencing life-threatening symptoms, please call 911.

What is coronavirus? 
Coronaviruses are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). They can infect humans and animals and can be transmitted between animals and people. Several coronaviruses can cause respiratory infections. The most prevalant and rapidly spreading contagious virus at this time is Covid-19.
What is COVID-19?
An infectious disease caused by a recently discovered coronavirus. In most people, it causes mild illness. However, a fraction of cases are severe.
How does COVID-19 spread?
COVID-19 spreads through small water droplets from the nose or mouth of people who have the virus. The CDC recommends the following:
  • Avoid close contact with people who are sick
  • Avoid touching your eyes, nose, and mouth
  • Stay home if you are sick
  • Cover your cough or sneeze with a tissue
  • Clean and disinfect frequently touched objects and surfaces (for example: tables, doorknobs, light switches, handles, desks, toilets, faucets, sinks & cell phones)
  • Wash your hands with soap and water frequently and for at least 20 seconds especially after blowing your nose, coughing or sneezing, or having been in a public place.
  • If soap and water are not available, use a hand sanitizer that contains at least 60% alcohol.
  • Wash your hands after touching surfaces in public places.
  • Avoid touching high-touch surfaces in public places–elevator buttons, door handles, handrails, handshaking with people, etc. Use a tissue or your sleeve to cover your hand or finger if you must touch something.
  • Avoid crowds, especially in poorly ventilated spaces. Your risk of exposure to respiratory viruses like COVID-19 may increase in crowded, closed-in settings with little air circulation if there are people in the crowd who are sick.
Watch for symptoms and emergency warning signs:
  • Pay attention for potential COVID-19 symptoms including fever, dry cough and shortness of breath. If you feel like you are developing symptoms, call your doctor.
  • f you develop emergency warning signs for COVID-19 get medical attention immediately. Emergency warning signs include:  Difficulty breathing or shortness of breath, Persistent pain or pressure in the chest, Bluish lips or face, new confusion or inability to rouse.
What should you do if you get sick?
  • Stay home. Going out may infect others. Avoid other household members, too.
  • If possible, wear a face mask and practice good hygiene. Wash your hands often and disinfect surfaces. 
  •  If you need treatment, call ahead. Do not go to the Emergency Room or Urgent Care. Please allow your doctor to prepare for your visit or contact you with advice.
  • If you are experiencing symtptoms or are at risk, so we can minimize the risk to other patients in the office, we are opening up appointment times for virutal visits. Call the office to get more information on how to get access.
And of course consult your health care team for other tips on preventing the spread of COVID-19.

​​​​​​​Meningococcal Meningitis can spread quickly, and teenagers and young adults are at greatest risk.

Is your teen going off to  college soon?  Have they received their Menactra Booster?  As you are busy checking off the dorm supply list make sure to add getting the vaccine to your to-do list.

So what is meningitis? Meningitis is an inflammation of the protective layer around the brain and spinal cord.This inflammation can be caused by a virus, a bacterium, or even a fungus.
  • Viral meningitis is the most common form. It is serious but generally not life threatening, and it usually goes away in 7 to 10 days.
  • Bacterial meningitis is rare, but it is very serious and potentially fatal. It includes meningococcal disease.
Meningococcal disease, can progress quickly. It can make an infant or teenager very sick and may even be life threatening. Meningococcal disease spreads just like the flu, passing from person to person through everyday activities. Some people carrying the bacteria never get sick, so they might pass it to others without knowing.
According to the CDC, teenagers and young adults are most likely to get meningitis. Research has shown that the following activities put teenagers and young adults at greater risk:
  • Living in close quarters, such as college dormitories
  • Being in crowded situations for prolonged periods of time (such as locker rooms)
  • Sharing drinking glasses, water bottles, or eating utensils
  • Kissing
  • Staying out late and having irregular sleeping patterns, which weakens the immune system.
Meningococcal meningitis symptoms
Meningococcal meningitis can be difficult to diagnose because its most common symptoms – fever, headache, and muscle pain – may be similar to those of influenza (flu). The symptoms of meningitis can occur suddenly and include:
  • Headache
  • Fever
  • Stiff neck or other muscle pain
  • Nausea and vomiting
  • Sensitivity to light
  • Confusion
  • Rash
  • Seizures
Meningococcal disease is rare. But just how serious is it? Did you know that:
  • Up to 1 in 5 survivors suffer brain damage, amputations, kidney damage, and more
  • As many as 1 in 8 people who get the disease die from it
  • The disease can kill a child in just 24 hours
If your child has symptoms – especially if they’ve been around someone with meningitis – contact a doctor immediately. When it comes to treating this potentially deadly disease, speed is essential.

Don’t take chances with meningitis. You can’t monitor everything your kids do. But you can help protect your child against meningococcal disease and its potentially deadly complications with Menactra vaccine. Menactra is a safe and effective vaccine that helps protect against meningococcal disease.

Your child should receive their first Menactra vaccination at age 11 through 12 years, with a booster dose at age 16 through 18 years. Talk to your doctor to see if your child has been vaccinated or needs a booster or for any questions you may have.

If you haven’t heard about the risks of HPV-related cancers and disease yet, it’s time you did. HPV (short for human papillomavirus) is a virus that can infect both males and females and cause potentially serious diseases.
As a parent, you know it’s important to have a healthy diet and regular checkups at the doctor’s office, but you may not know that exposure to HPV can put your child at risk for HPV-related cancers and diseases later in life. 
There are approximately 14 million new HPV infections in the United States every year — about 50% of them in 15- to 24-year-olds. For most, HPV clears on its own. But, for others who don’t clear the virus, HPV could cause potentially serious diseases. Unfortunately, there’s no way to predict who will or won’t clear the virus. Understanding HPV and its possible consequences is the first step in helping your child be one less at risk for certain HPV-related cancers and diseases.
Currently, there are about 79 million Americans infected with HPV, according to the Centers for Disease Control and Prevention (CDC). Each year, 14 million new infections occur in the United States and about half of the newly infected people are 15 to 24 years old.
Please speak to your Doctor about getting your teen the Gardasil Vaccine.

 All Adults 50 years and older should receive the vaccine to fight Shingles

What You Need to Know :
Shingles is a painful rash that usually develops on one side of the body, often the face or torso. The rash consists of blisters that typically scab over in 7 to 10 days and clears up within 2 to 4 weeks. Some people describe the pain as an intense burning sensation. For some people, the pain can last for months or even years after the rash goes away. This long-lasting pain is called postherpetic neuralgia (PHN), and it is the most common complication of shingles. Your risk of getting shingles and PHN increases as you get older.

In the U.S., currently 1 million people get shingles every year, and about one out of every three people will get shingles in their lifetime. Shingles, also known as zoster or herpes zoster, is a painful skin rash caused by the varicella zoster virus, the same virus that causes chickenpox.  The virus stays dormant (inactive) in the body and can reactivate years later and cause shingles.
A new shingles vaccine called Shingrix was licensed  by the FDA in 2017. CDC recommends that healthy adults 50 years and older get two doses of Shingrix, 2 to 6 months apart. Shingrix provides strong protection against shingles and PHN. Shingrix is the preferred vaccine, over Zostavax®, a shingles vaccine in use since 2006.

 Even people who have had shingles or previously got Zostavax can be vaccinated with Shingrix to prevent shingles and the complications caused by the disease.
To learn more about Shingles speak to your Doctor
