At least with monkeypox, it’s not a brand-new virus.”She added, “But the current outbreak has a number of features to it that are different from prior outbreaks.”Signs and symptomsThe incubation period from the time a person is exposed to when symptoms first appear can range from three days to 17 days, according to the Centers for Disease Control and Prevention.The most common symptom is a rash that can appear on the arms, legs, chest or face or on or near the genitals, the health agency said.Lesions start out as dark spots on the skin before progressing to bumps that fill with fluid and/or pus.Finally, the lesions will scab over and eventually fall off. People may be left with scars or skin discoloration, but health officials say a person is no longer infectious once the scabs are gone and a fresh layer of skin has formed.Other symptoms include fever, headache, fatigue, chills, muscle aches, backache and swollen lymph nodes.What treatments are availableMost monkeypox patients recover within two to four weeks without specific treatments and receive “supportive care” such as Tylenol for fever or topical pain relievers for rashes.However, some patients at high risk of severe illness, such as those with weakened immune systems, may benefit from treatment.“We have an antiviral medication we can offer to patients if they need a little more help handling the rash,” Andujar Vasquez said. “But that would be for a subset of patients. Not every patient needs to be on antiviral medication.”Tecovirimat, known under the brand name TPOXX, is a two-week course of pills approved by the U.S. Food and Drug Administration to treat smallpox.However, TPOXX was made available to treat monkeypox under “compassionate use” by the CDC after animal studies showed it can lower the risk of death.Vaccines that can protect against infectionThere are two vaccines that can be used to prevent monkeypox.The only one currently being used is JYNNEOS, which is a two-dose vaccine approved by the FDA to prevent smallpox and monkeypox.“We would give the vaccine ideally by four days from your exposure, but we think it may be still beneficial to do it if it’s been 14 days after you were exposed,” Andujar Vasquez said.Data from Africa has shown two doses of JYNNEOS are at least 85% effective in preventing monkeypox infection.The other vaccine, ACAM2000 — which the U.S. has in a stockpile — is not being used because it has been shown to cause side effects in people with certain conditions, such as those who are immunocompromised.To increase the number of JYNNEOS doses available, health officials announced Tuesday they would be implementing a new strategy to inject the vaccine intradermally, just below the first layer of skin, rather than subcutaneously, or under all the layers of skin.This will allow one vial of vaccine to be given out as five separate doses rather than a single dose.Prevention methodsThe experts say for most Americans, the risk for monkeypox is still low. However, they recommend proper hand hygiene and following CDC guidelines for practicing safer sex.“It’s worth it to pay attention to what’s happening with monkeypox, but I would not worry about shaking hands with people [without monkeypox] or opening doors or touching surfaces,” Justman said.Copyright © 2022, ABC Audio.
