    On chikungunya acute infection and chloroquine treatment

    The fever is usually above 39 °C (102 °F) and sometimes reaching 40 °C (104 °F) and may be biphasic—lasting several days, breaking, and then returning. Fever occurs with the onset of viremia, and the level of virus in the blood correlates with the intensity of symptoms in the acute phase.

    Chikungunya infection treatment for acute supportive care include analgesics and antipyretics such as acetaminophen Tylenol® or paracetamol to reduce fever and pain. It is wise to avoid aspirin and NSAIDs until dengue fever has been excluded. In their Review on chikungunya, Gilles Pialoux and colleagues1 quote a Reflection and Reaction commentary previously published by our group2 as the source for the statement that “a clinical trial in South Africa failed to confirm the clinical efficacy of chloroquine on arthralgia”. It is true that chloroquine displays antiviral and anti-inflammatory properties that, in our opinion, merit. Due to the alkalisation of endosomes, chloroquine was an effective in vitro treatment against Chikungunya virus when added to Vero cells prior to virus exposure. The mechanism of inhibition likely involved the prevention of endocytosis and/or rapid elevation of the endosomal pH and abrogation of virus–endosome fusion.

    However, headache, insomnia and an extreme degree of exhaustion remain, usually about five to seven days. When Ig M, an antibody that is a response to the initial exposure to an antigen, appears in the blood, viremia begins to diminish.

    In a nonhuman primate model of CHIKV infection, chloroquine treatment was shown to exacerbate acute fever and delay the cellular immune response, leading to an incomplete viral clearance Roques et al. 2018. If you have chikungunya, prevent mosquito bites for the first week of your illness. During the first week of infection, chikungunya virus can be found in the blood and passed from an infected person to a mosquito through mosquito bites. An infected mosquito can then spread the virus to other people. Treatment for patients with chronic chikungunya arthritis remains investigational. Limited data suggests that immunosuppressive therapies such as methotrexate and TNF alpha inhibitors may be beneficial, though randomized clinical trials are needed.
