How a Joke About Flying Squirrels Led to an Ailing Woman’s Cure – New York Times

A Hidden Infection?

The doctors at South County werent sure what was going on, either. The patient felt sick: She was tired, her back was killing her and she felt weak all over. She looked sick too: pale and frail. On exam, her temperature was up and her blood pressure was down. She had a faint rash on much of her body, and she was confused. But her white-blood-cell count an indicator of infection wasnt elevated, and the doctors couldnt see any obvious source of infection. Blood tests showed no signs of the most common tick-borne diseases. A chest X-ray was normal. An ultrasound of her abdomen was, too. Blood was also analyzed to see if any bacteria would grow, and she was admitted to the hospital team, under the care of Caroline Jenckes, an experienced nurse practitioner.

Jenckes spent the next few days looking for an infection she was certain was there. She ordered an M.R.I. of the spine in search of an abscess, but found nothing. The patients gallbladder was carefully evaluated; inflammation can trigger a fever and pain that travels to the back. A couple of days in, a CT scan of the patients chest suggested the possibility of pneumonia. Dr. Fred Silverblatt, the infectious-disease doctor Jenckes consulted, didnt think the subtle findings could be the cause of her symptoms. And the patients fever was already coming down. Still, he agreed to start her on broad-spectrum antibiotics.

Finally the medical team saw what seemed significant evidence that the patient was getting better. Her fever came down, and her blood pressure returned to normal. Her back pain was subsiding.

From the sons perspective, his mother was not really recovering. He and his wife had been taking turns staying with her, day and night, and she was nothing like her old self; she still seemed quite sick. Despite the antibiotics, she remained tired, weak and practically speechless. The son called his sister in Maryland and older brother in Missouri to tell them that this might be the end, and the siblings hurried to their hometown.

The frail woman didnt open her eyes when her older son entered the room. He leaned close to give her a kiss and straighten her up in the bed. Did she have flying-squirrel fever, he asked lightly, referring to their effort the autumn before to rid her attic of the pesky rodents. Back then she told him how cute the big-eared babies were, creatures taken out of the attic by the exterminator on their way to relocation. He thought she smiled a bit at his joke, just a whisper of her usual good humor. But as he made the joke, he suddenly had a thought: Could those squirrels have anything to do with this strange illness that no one could figure out?

It was an odd thought but the kind of connection that inspired the son, so he found a computer in the hospital and searched online a bit. The first pages carried mostly ads for services to get rid of the pests. But then he found something: a short article from the Centers for Disease Control and Prevention linking flying squirrels with something called epidemic typhus. Further reading revealed that the symptoms of typhus fever, body aches, rash and confusion resembled those his mother had. But typhus was a rare infection. There had been fewer than 100 cases in the United States reported to the C.D.C. over the past 40 years.

Still, the son printed out the article and went in search of Caroline Jenckes. He explained that his mothers house had been infested with these animals. Jenckes was intrigued with the idea. Certainly all the studies theyd done to find the source of the womans symptoms had been unrevealing. She took the article to Silverblatt. It seemed to him a perfect fit: the symptoms, the exposure, the minimal response to the antibiotics. He read up a little more on the infection before starting the patient on the appropriate antibiotic doxycycline and sending her blood to the C.D.C. for confirmation.

Epidemic typhus is an old disease. Since the Middle Ages, periodic epidemics of this infection killed millions of people. Just after World War I, an outbreak in Russia killed three million. The infection is often transmitted through contact with a body louse. Modern sanitation has significantly reduced the incidence of both infection and carrier. In the United States, most cases of typhus have come from exposure to flying squirrels. Its not clear how the bacteria get from the rodents who harbor the bug to the humans they infect, but the louse once again plays a role. Squirrel lice do not tend to bite humans, so it is thought that exposure occurs when bacteria in lice excrement are inhaled.

After 24 hours on the new antibiotic, the woman was transferred to a rehabilitation facility. Within days she began to act more like herself. She was irritated that she had been placed on the floor designated for the sick and dying. She was certain, she explained to anyone who would listen, that this was not where she belonged. She says she didnt really start to get better until she moved to the floor for healthier patients.

After a few weeks she was well enough to go home. It took almost that long for the test results to come back confirming typhus. While she recovered, her children arranged for an exterminator to get rid of any squirrels that might have returned and to seal up any possible ports of re-entry.

Families are an essential source of information about patients and the world they live in. They dont usually make the diagnosis, but they can provide answers to questions doctors hadnt considered asking. In this case, the knowledge of this womans exposure and its associated infection may have saved her life. Untreated epidemic typhus can kill up to 30 percent of patients, and the very old are at the greatest risk.

All this happened three years ago. If you ask this woman now how shes doing, shell immediately inform you that shes just great because the more shes on her own, the better she feels.
