Background: Maternal to fetal transmission of chikungunya infection is reported in various studies. However, there is no study from India that looked at the pregnancy outcomes in patients infected with chikungunya. Thus, we planned an observational study that looked at the short-term outcomes of chikungunya infection on pregnancy outcomes. Materials and Methods: It was an observational study conducted at a private clinic in New Delhi from August 2016 to October 2016. We recruited 150 consecutive pregnant females from the outpatient that were suspected chikungunya infection and subsequently tested positive for the same. Those patients who fulfill the inclusion and exclusion criteria would be followed till 10 days including the time till fever subsided. Pregnancy outcomes would be noted in these subjects based on history, examination, and investigations. Results: Out of 150 patients, 141 (94%) recovered completely within 10 days of onset of symptoms. Only nine patients had persistent arthralgias. In our study, mean age (years) ± std was 24.52 ± 3.765, mean period of gestation (months) ± std was 25.62 ± 13.475, and mean period of gestation at delivery (months) ± std was 36.36 ± 3.225. Most of our patients, 75 (50%) were in 2nd trimester, 24 (16%) were in first trimester, and 51 (34%) in third trimester. Pregnancy complications were seen in 30 (20%) patients. Preterm delivery (<36 weeks) were seen in 11 (7.33%), premature rupture of membranes were seen in 5 (3.33%), decreased fetal movements in 4 (2.67%), intrauterine deaths in 4 (2.67%), oligohydromnios in 3 (2%), and preterm labor pains 3 (2%). There were six patients who underwent delivery at term. In our study cohort, 30 (20%) developed adverse pregnancy outcomes which were maximum during third trimester –24/30 (80%). Conclusion: Chikungunya infection in pregnancy is associated with increased pregnancy morbidity and fetal mortality.

| Introduction|| |
Chikungunya fever is caused by chikungunya virus (CHIKV) which is an alphavirus of the Togaviridae family; their potential vectors are aedes mosquito (1*). CHIKV has caused numerous epidemics especially in Africa, Indian subcontinent, and countries of Southeast Asia.,, Clinical manifestations of chikungunya fever are fever, headache, myalgia, exanthema, and arthralgia. Arthralgia is its most pronounced symptom which may persists in some patients for months to years and may evolve into disabling chronic arthropathy (2, 3*) Organ involvement as neurological and cardiac is limited to case reports., Chikungunya infection has been reported to affect pregnancy outcomes. CHIKV can be transmitted vertically from mother to fetus. The first case of virus transmission from mother to child at birth was reported in February 2006; from Reunion island., There are reports of spontaneous abortion after an infection by chikungunya virus. It has been found that chikungunya virus produces cytopathic effects in cellular lines as Vero cells, BHK-21, and HeLa.
To the best of our knowledge, there is no study showing the impact of chikungunya infection on pregnancy outcomes from a country like India where this infection occurs as an epidemic. Thus, we decided to carry out this study looking at the short-term outcomes of pregnancy in patients infected with chikungunya virus.
| Materials and Methods|| |
A prospective, observational study shall be conducted at a private rheumatology clinic from August 2016 to October 2016. The study observed the short-term outcome of chikungunya infection on pregnant females. We aimed to study the short-term outcome on pregnancy following chikungunya infection.
Pregnant females who presented to the outpatient clinic with symptoms of fever were included in the study. These patients were screened for the etiology of fever. Those patients with suspected chikungunya fever (fever with arthralgia) were included in the study. A confirmatory serology was sent for case confirmation. A total of 150 consecutive pregnant patients who tested positive for the serology were included in the study. Patients with negative serology were excluded. chikungunya serology was done and immunoglobulin M (IgM) detection assays were done by Euroimmune capture enzyme linked immunosorbent assays.
- Pregnant females with confirmed chikungunya
- Fever etiology other than chikungunya infection
- Pregnant females with other coexisting disease/comorbidity or fetal disease or defect.
Those patients who fulfill the inclusion and exclusion criteria were followed till 10 days including the time till fever subsided. Pregnancy outcomes were noted in these subjects based on history, examination, and investigations.
The results are expressed as mean ± standard deviation. The clinical manifestations and outcomes were expressed as percentages.
| Results|| |
We did an observational study and looked at the short-term outcome (10 days) of the pregnancy in patients who developed chikengunya infection during the gestational period. We included patients who were seropositive for chikungunya. Patients of chikungunya were managed by high fluid intake, paracetamol, nonsteroidal anti-infl ammatory drugs – diclofenac 100 mg twice a day. Baseline characterstics of our cohort has been shown in [Table 1]. Out of 150 patients, 141 (94%) recovered completely within 10 days of onset of symptoms. Only nine patients had persistent arthralgias.

Among the patients recruited in our study, 63 (42%) were primigravida, 50 (33.3%) were second gravida, and third gravid were 37 (24.7%) in number. In our study, most of the women were nullipara, i.e., 52 (34.67%), 44 (29.33%) were para 1; 32 (21.33%) were para 2 and para 4 were 22 (14.87%).
Most of our patients 75 (50%) were in second trimester, 24 (16%) were in fi rst trimester, and 51 (34%) in third trimester.
During this 10-day period Bleeding was not seen in any patient.
Complications of pregnancy were seen in many patients as shown in [Table 2].

Out of 150 patients with chikungunya infection, 30 (20%) developed adverse pregnancy outcomes. Most of the adverse pregnancy outcomes occurred during third trimester – 24/30 (80%), while rest 6 (20%) adverse outcomes occurred during second trimester and none during first trimester.
There were six patients who underwent delivery at term.
Out of the 17 deliveries, 11were caesarian and 6 were normal vaginal deliveries.
| Discussion|| |
Chikungunya infection is a re-emerging infection and is becoming a major public health problem in India. There are a few studies which have shown that chikungunya virus can be transmitted from mother to fetus. Early maternal–fetal transmission of chikungunya virus before 16 weeks of gestation has also been described which has resulted in fetal deaths. There are studies showing that when maternal infection occurs at the end of pregnancy, due to the higher viral concentrations most of the neonates develop complications.
With the above data, we devised a study to find the short-term outcomes of pregnant females who were infected with chikungunya virus. We found that 30 (20%) pregnant females with this infection developed adverse pregnancy outcomes as preterm delivery, premature rupture of membranes, decreased fetal movements, intrauterine death, oligohydramnios, and preterm labor pains.
The effect of chikungunya virus on pregnancy outcomes have been studied in some studies as Done at Re-union island, in the Groupe Hospitalier Sud-Reunion cohort study, CHIMERE (”Chikungunya Mere-Enfant”) cohort study  and 2004–2006 Family Allowance Office (41,665 deliveries) and Mother and Child Welfare (42,259 neonates) records.
There is no convincing evidence that chikungunya virus exposure in the first trimester of gestation is linked to an increased risk for miscarriage or congenital malformation.,
| Conclusion|| |
These results will spread awareness about the possibility of mother-to-child transmission of chikungunya virus and its consequences. Thus, such knowledge may help the specialists to improve its future management.
